FUEL OIL

Description

/ 4 “FUEL OIL”. From the field of application

[001] This is a viscous hydrophobic fluid that falls within the technical sector of chemically processed substances and products capable of being burned and / or used in the production of energy, generally in the form of heat and / or mechanized work. From the product

[002] More precisely, the product in question refers to a heavy fuel oil derived from petroleum derivatives, produced from the chemical recycling and energy recovery of solid polymeric waste and classified as Styrene Butadiene Rubber (SBR), presenting potential application as an alternative and industrial fuel with high calorific value, in addition to an essential flash point for ignition in industrial processes, also standing out for the fact that it presents differentials and advantages for its production and application, since it promotes sustainability with a circular economy, using polymeric industrial waste that is collected and destined for the production of the oil without the total need for petroleum extraction, also enabling a more adequate treatment for a type of polymeric industrial waste that represents a recognized environmental problem. Regarding the method of obtaining

[003] The fuel oil now disclosed is obtained through the thermal process of pyrolysis, in which the transformation of solid polymeric residues occurs, converting them into Petition 870250116504, dated 12 / 17 / 2025, page 5 / 11 / 4 respective hydrocarbons in a high-value alternative liquid fuel, in addition to generating energy sustainably. Of the existing problems

[004] As is known mainly by those skilled in the art, as well as by all those directly or indirectly involved in this sector, traditional oil requires the extraction of petroleum, bringing the ecological drawback related to the high generation of polymeric industrial waste, among them, SBR, whose major problem lies precisely in the disposal process of these materials, which are often carried out in inappropriate locations, such as the sea, rivers, open dumps (landfills), sanitary landfills or even incinerated, which inevitably causes environmental pollution, considering also the fact that its natural degradation can take billions of years, causing the contamination of water bodies, soil and air by toxic chemical substances. State of the art

[005] Regarding the state of the art, there is no knowledge of the existence of complementary information and / or patent documents that present exactly the same combinations of characteristics revealed in the matter discussed here. From the composition

[006] The oil samples were analyzed by gas chromatography coupled to mass spectrometry (GC-MS), and the composition of the oils obtained from pyrolysis was determined through GC-MS analysis, identified by means of Petition 870250116504, dated 12 / 17 / 2025, page 6 / 11 / 4 chromatograms and their relation to the NIST (National Institute of Standards and Technology) database, with the compounds resulting from the pyrolysis of SBR (styrene-butadiene rubber) and which are part of the now disclosed fuel oil being duly presented in the detailed table below, noting that the peak area in % corresponds to that of the product formed, since the sum of the total area is 99.99:Sequential Identification TR (min) Area (%) Compound Molecular Formula Mass CAS 01 5.63 10.85 Toluene C7H8 92 108-88-3 02 7.74 30.02 Ethylbenzene C8H10 106 100-41-4 03 7.92 2.912 p-Xylene C8H10 106 106-42-3 04 8.40 12.81 Styrene C8H8 104 100-42-5 05 9.16 8.231 Benzene, (1-methylethyl)- C9H12 120 98-82-8 06 9.82 1.497 Benzene, propyl- C9H12 120 103-65-1 07 10.02 2.985 Benzene, 1-ethyl-3-methyl-C9H12 120 620-14-4 08 10.43 5.083 .alpha.Methylstyrene C9H10 118 98-83-9 09 10.70 1.236 Benzene, 1,2,4-trimethyl- C9H12 120 95-63-6 10 11.35 4.878 Benzene, 1-methyl-3-(1-methylethyl)- C10H14 134 535-77-3 11 12.02 1.602 Benzene, butyl- C10H14 134 104-51-8 12 14.00 1.477 Benzene, 2-ethenyl-1,4-dimethyl- C10H12 132 2039-89-6 13 14.72 4.499 Naphthalene C10H8 128 91-20-3 14 16.77 1.547 Naphthalene, 1-methyl- C11H10 142 90-12-0 15 21.07 3.365 Acetic acid, (2-isopropenylcyclopentylidene)-, methyl ester C11H16O 2 180 176753-50-7 16 22.49 3.341 Benzene, 1,1'-(1,3-propanadiyl)bis- C15H16 196 1081-75-0 17 23.07 3.652 Phenol, 2,6-dimethoxy-4(2-propenyl)- C11H140 3 194 6627-88-9.

[007] With regard to the production stages, its raw material (SBR) is received in big-bags, plastic bags and other types of suitable packaging, which remain in appropriate locations, being subsequently directed to a feeder funnel coupled to a pipeline, and conveyed, by means of a helical conveyor, to the interior of the reactor, in which the pyrolysis process will occur, decomposing the aforementioned raw material by subjecting it, for approximately six hours, to a temperature of 6000C, during which period its molecules are broken, releasing and generating gases during the pyrolysis process that are sent to the condensers responsible for cooling and changing from the gaseous to the liquid state, producing pyrolytic oil, subsequently stored in tanks with a capacity of 15,000 liters.
