Recycling process and recycled product

Abstract

A specific recycling process and recycled products obtained by the recycling process are described herein.

Description

[0001] Waste containing organic contents, such as polymers, can be recycled in several ways, such as through gasification, to obtain chemical materials, such as small molecules or monomers. The chemical materials obtained in this recycling process can be used to produce recycled products, such as recycled polymer products. Even if a particular waste contains a significant amount of desired carbon and hydrogen, it often also contains substantial amounts of contaminants, such as halogenated organic compounds, salts, or metals, compared to fossil feedstocks. These contaminants, especially the volatile ones, are dragged along the recycling process, shortening maintenance intervals of the recycling equipment, damaging or even completely destroying the equipment, and ultimately remaining in the obtained chemical materials. Once present in the recycled chemical materials, separating contaminants from them is extremely complex, and in some cases, the separation effort outweighs the benefits of recycling the chemical materials. However, if contaminants are present in the recycled chemical materials, they can damage mechanical parts, for example, through corrosion. Therefore, contaminants in chemical materials can cause serious damage in downstream production equipment, for example, for producing new polymers and / or polymer compositions. Furthermore, contaminants can cause undesirable side reactions during downstream chemical conversions, resulting in the recycling of end products containing byproducts. Moreover, contaminants may irreversibly embed themselves in the recycled product. Consequently, the recycled product may be unusable. However, the extent of contaminant removal in recycling equipment necessary to obtain high-quality recycled chemical materials has not been adequately investigated.

[0002] Therefore, one object of the present invention is to provide an improved method, particularly wherein the method:

[0003] - Demonstrates improved protection for recirculation equipment; and / or

[0004] - Provide improved chemical materials; and / or

[0005] - Provide chemical materials suitable for downstream processes; and / or

[0006] - Achieve higher productivity.

[0007] The specific methods described herein yield improved chemical materials that can be further converted into polymer compositions and products. Therefore, another object of the present invention is to provide an improved recyclable chemical material, polymer, polymer composition, and / or polymer product, particularly wherein the chemical material, polymer, polymer composition, and / or polymer product:

[0008] - Protect downstream production equipment; and / or

[0009] - Possesses high quality; and / or

[0899] Methods and Definitions

[0900] Unless otherwise specified, the following method is preferred, and definitions apply.

[0901] Content Measurement: Samples (e.g., waste, pyrolysis oil, or syngas) may contain solid, liquid, gaseous contents, or mixtures thereof. Those skilled in the art are familiar with several methods for determining the content of elements in a sample, such as GC / ICP / MS. Content can be determined by any of these methods.

[0902] Preferably, the following method is used:

[0903] The content of one or more contaminants in the starting materials, raw materials, and chemical materials was measured at 25°C and 1013 mbar. Furthermore, unless otherwise specified, the content of one or more contaminants is the average of 10 representative 3 kg samples collected by a person skilled in the art.

[0904] The content (e.g., the content of one or more pollutants) in the gas phase was determined in the headspace at 25°C and 1013 mbar.

[0905] Prior to analysis, all solid or solid-liquid samples are homogenized, for example, by crushing or mixing, preferably to a particle size of about 3 mm or less. The solid and liquid contents are separated by sieving, preferably by a sieve with a pore size of 0.1 mm, and the contents in the liquid and solid phases, such as the content of one or more contaminants, are then determined. Separation is preferably carried out under ambient conditions, preferably 25°C and 1013.25 mbar.

[0906] Preferably, the content is determined according to the standards listed in Tables 1 to 3, for example, the content of one or more pollutants:

[0907] Table 1: Standards for determining the content in solid phases :

[0908]

[0909] Table 2: Standards for determining the content in liquid phase :

[0910]

[0911] *Method C / H: A sample of 4 to 5 mg was combusted in a helium / oxygen atmosphere. After separation of the combustion gases, carbon was identified as CO2 and hydrogen as H2O. Detection and quantification were performed via thermal conductivity (analyzer: Elementar, model Vario MicroCube).

[0912] Table 3: Standards for determining the content in the gas phase :

[0913]

[0914] GC / ICP / MS is gas chromatography-inductively coupled plasma mass spectrometry and is well known to those skilled in the art (e.g., the Agilent 8890 GC with 8900 ICP-MS / MS). Iron, mercury, and silicon in the gas phase were not determined and were set to 0 wt%.

[0915] Preferably, when one or more pollutants consist of each element other than hydrogen (H) and carbon (C), the content of one or more pollutants is preferably determined by determining the content of hydrogen (H) and carbon (C) using the following formula: (content of one or more pollutants) = 100% by weight - ((content of hydrogen (H) in weight%) + (content of carbon (C) in weight%)). If one or more pollutants consist of each element other than hydrogen (H), carbon (C), and oxygen (O), preferably hydrogen (H), carbon (C), oxygen (O), sulfur (S), and nitrogen (N), the content of one or more pollutants is preferably determined in a similar manner.

[0916] In this paper, if the denominator has a value below the detection limit and the numerator has a value above the detection limit, the value obtained in the fraction is 1. For example, if the fraction is cC-CM1 / cC-SM1, and the content of one or more contaminants C-CM1 in the chemical material CM1 is above the detection limit by weight, and the content of one or more contaminants C-SM1 in the starting material SM1 is below the detection limit by weight, then cC-CM1 / cC-SM1 is 1.

[0917] In this paper, if both the denominator and numerator have values ​​below the detection limit, the value obtained in the fraction is 1. For example, if the fraction is cC-CM1 / cC-SM1, and the content of one or more contaminants C-CM1 in the chemical material CM1 is below the detection limit (by weight), and the content of one or more contaminants C-SM1 in the starting material SM1 is below the detection limit (by weight), then cC-CM1 / cC-SM1 is 1.

[0918] In this paper, if the numerator has a value below the detection limit and the denominator has a value above the detection limit, the value obtained in the fraction is 0. For example, if the fraction is cC-CM1 / cC-SM1, and the content of one or more contaminants C-CM1 in the chemical material CM1 is below the detection limit (by weight), and the content of one or more contaminants C-SM1 in the starting material SM1 is above the detection limit (by weight), then cC-CM1 / cC-SM1 is 0.

[0919] Furthermore, if the value is below the detection limit, it is set to 0. Therefore, if one or more contaminants consist of chlorine, silicon, and mercury, and the values ​​of chlorine and silicon are below the detection limit, and the value of mercury is 5% by weight, then the content of one or more contaminants is 5% by weight.

The treated oil vapors are then passed through a condenser to liquefy the desired hydrocarbons at approximately 45 °C and 1.2 kPa.

[1862] For polar extraction, the following standard method according to WO2023073059 was used: The pyrolysis oil was extracted with NaOH, specifically by introducing (5 L of pyrolysis oil) into a stirred 12 L steel vessel and mixing it with 1.5 L of deionized water. Next, a feed stream containing 0.3 M NaOH solution (3.5 L of 0.3 M NaOH solution) was pumped into the mixing unit (12 L steel vessel) over a 50-minute period while stirring. Once the 3.5 L of NaOH solution was added, the resulting mixture was further stirred for 30 minutes. Mixing was then stopped, allowing the two-phase mixture to settle overnight in the mixing unit. The pH of the aqueous mixture was measured and found to be approximately 8. The entire procedure (i.e., mixing and settling) was carried out at 40°C to dissolve the contained wax. The oil phase was separated from the aqueous phase; the aqueous phase was removed from the mixing / settling unit for wastewater treatment, and the oil phase was removed from the mixing / settling unit for subsequent downstream treatment.

[1863] For steam cracking, the following standard method is used (Ullmann's Encyclopedia of Industrial Chemistry, 2012, Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, https: / / doi.org / 10.1002 / 14356007.a10_045.pub3): The hydrocarbon stream is heated by heat exchange with flue gas in the convection section, mixed with steam, and further heated to the initial cracking temperature (500°C to 680°C, depending on the feedstock). The stream then enters a combustion tubular reactor, where it is heated to 750°C to 875°C kPa and held for 0.1 to 0.5 s under controlled residence time, temperature distribution, and partial pressure. During this short reaction time, the hydrocarbons in the feedstock crack into smaller molecules; ethylene, other olefins, and dienes are the main products. The reaction products exiting the radiant tube at 800°C to 850°C are cooled to 550°C to 650°C within 0.02s to 0.1s. The cracked gas in the delivery line heat exchanger is cooled by vaporization of high-pressure boiler feedwater (BFW, p=6MPa to 12MPa), which is separated in a steam drum and subsequently superheated in the convection section to high-pressure superheated steam (HPSS, 6MPa to 12MPa).

[1864] The following describes how specific waste streams are recycled:

[1865] In the first experiment, waste containing foil, serving as the starting material (SM1) containing contaminant C-SM1, was first pyrolyzed to obtain raw material RM5 containing contaminant C-RM5. Then, raw material RM5 was treated by a polar extraction step to obtain raw material RM6 containing C-RM6. Contaminants in raw material RM6 were removed compared to raw material RM5. Finally, raw material RM6 was steam-cracked to obtain raw material RM4 containing contaminant c-RM4, which was further converted and removed (standard methods: distillation, separation, hydrocracking) to obtain chemical material CM1 containing contaminant C-CM1. The contents of contaminants N, S, and Cl, and the sum of all contaminants, are listed in Table 4 below. If cCM1SM1-1 has the values ​​shown in Table 4, this method provides chemical material CM1 suitable for downstream processes. The yield of raw material RM5 in this method is 60%.

[1866] In the second experiment, paper mill waste, used as starting material SM1, was mixed with foil-containing waste (1:1 [weight:weight]) to obtain raw material RM1 containing contaminant c-RM1. Then, raw material RM1 was pyrolyzed as described above to obtain raw material RM2 containing contaminant C-RM2. Raw material RM2 was then treated by a polar extraction step to obtain raw material RM3 containing C-RM3. Contaminants in raw material RM3 were removed compared to raw material RM2. Finally, the removed raw material RM3 was steam-cracking to obtain chemical material CM1 containing contaminant c-CM1. The contents of contaminants N, S, and Cl, and the sum of all contaminants, are listed in Table 5 below. If cCM1SM1-1 has the values ​​shown in Table 5, the method provides chemical material CM1 suitable for downstream processes. In particular, by diluting the starting material SM1, which contains high levels of sulfur and chlorine, these values ​​are sufficiently reduced during the recycling process, making the method provide chemical material C...
