Problems solved by technology

Some materials also have secondary pollution and disposal problems of waste adsorbents
In addition, most of the existing desulfurizers use activated carbon, ZSM-5 and other materials, and clay is rarely used due to its own structure.

Embodiment 1

[0017] In the embodiment of the present invention, a clay desulfurizer is composed of the following raw materials in parts by weight: 28 parts of clay, 1 part of pectin, 3 parts of perillaldehyde, and 11 parts of acetic acid.

[0018] Acetic acid solution is prepared by mixing acetic acid with 6.8 times its mass of ethanol with a volume concentration of 65%. Mix and grind the clay and pectin for 1.5h, then add acetic acid solution, raise the temperature to 69°C and seal and stir at this temperature for 1.9h, then raise the temperature to 83°C and add perillaldehyde dropwise, after the dropwise addition is completed, at this temperature Ultrasonic treatment for 22 minutes, the ultrasonic power is 1000W, and then stirred at a temperature of 99 ° C until dry, and then calcined in a muffle furnace at 440 ° C for 4.3 hours to obtain the desulfurizer.

Embodiment 2

[0020] In the embodiment of the present invention, a clay desulfurizer is composed of the following raw materials in parts by weight: 36 parts of clay, 5 parts of pectin, 7 parts of perillaldehyde, and 19 parts of acetic acid.

[0021] Mix acetic acid with 6.8 times its mass of 65% ethanol to prepare an acetic acid solution. Mix and grind clay and pectin for 1.6h, then add acetic acid solution, raise the temperature to 69°C and seal and stir at this temperature for 1.9h, then raise the temperature to 83°C and add perillaldehyde dropwise. Ultrasonic treatment for 22 minutes, the ultrasonic power is 1000W, and then stirred at a temperature of 101 ° C until dry, and then calcined in a muffle furnace at 440 ° C for 4.3 hours to obtain the desulfurization agent.

Embodiment 3

[0023] In the embodiment of the present invention, a clay desulfurizer is composed of the following raw materials in parts by weight: 30 parts of clay, 2 parts of pectin, 4 parts of perillaldehyde, and 13 parts of acetic acid.

[0024] Mix acetic acid with 6.8 times its mass of 65% ethanol to prepare an acetic acid solution. Mix and grind clay and pectin for 1.55 hours, then add acetic acid solution, raise the temperature to 69°C and seal and stir at this temperature for 1.9 hours, then raise the temperature to 83°C and add perillaldehyde dropwise, after the dropwise addition is completed, under this temperature Ultrasonic treatment for 22 minutes, the ultrasonic power is 1000W, and then stirred at a temperature of 100 ° C until dry, and then calcined in a muffle furnace at 440 ° C for 4.3 hours to obtain the desulfurization agent.

Abstract

The invention discloses a clay desulfurizer as well as a preparation method and an application thereof. The desulfurizer is prepared from raw materials in parts by weight as follows: 28-36 parts of clay, 1-5 parts of pectin, 3-7 parts of perillaldehyde and 11-19 parts of acetic acid. The clay is taken as a raw material and mixed with the pectin, the mixture is ground and then treated with acetic acid and perillaldehyde, and the desulfurizer is prepared. Gasoline with ultralow sulfur content being 6 mu g / g or below can be obtained under the condition that RON (research octane number) loss is lower than 2.0. The desulfurizer has good sulfur selectivity and high desulfurization degree, and the octane number loss caused by olefin hydrogenation saturation can be avoided while a sulfur-containing compound in gasoline is deeply removed. The desulfurizer is long in service life and environment-friendly, causes no secondary pollution and is good in regeneration performance. A preparation process is simple, easy to operate and control, stable in performance, low in production cost and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of gasoline, in particular to a clay desulfurizer and its preparation method and application. Background technique [0002] The ultra-deep desulfurization of gasoline has become an important problem to be solved worldwide. The combustion of sulfur in gasoline produces sulfur oxides (SOx), which is one of the main pollutants in the atmosphere. When it is discharged into the air, it will form acid rain and damage the ecological environment. In addition, sulfur oxides can also corrode and damage engine components, poison motor vehicle exhaust gas treatment catalysts, reduce their catalytic activity, increase the emission of particulate pollutants, and aggravate urban environmental pollution. Therefore, limiting the sulfur content is an important indicator in the standard of motor gasoline, and also a key factor in evaluating the cleanliness of gasoline. Only 34% of foreign gasoline blending components are cat...
