Abstract
Described herein are processes and related devices and systems for the conversion of higher hydrocarbons, such as in the form of waste plastics, petroleum sludge, slope oil, vegetable oil, and so forth, into lower hydrocarbons, which can be used as fuels or raw materials for a variety of industrial and domestic uses.
Claims11
A process for converting higher hydrocarbons comprising at least 25 carbon atoms into lower hydrocarbons comprising 2-25 carbon atoms, said process comprising:
- providing a feedstock comprising at least one solid waste raw material and at least one liquid waste raw material;
- heating the feedstock into at least one of a liquid and a liquid slurry;
- providing a first set of catalysts in a thin-film cracking device;
- passing the liquid or liquid slurry to the thin-film cracking device, wherein a thin film of the liquid or liquid slurry is wiped onto a heat transfer surface and cracked at a temperature in the range of 275° C. to 500° C. to produce a gaseous product, and conveying uncracked residues to a bottom of the thin-film device;
- restructuring the gaseous product, in the presence of a second set of catalysts, to produce a restructured gaseous product;
- and
- condensing the restructured gaseous product to produce a desired end product comprising lower hydrocarbons.
