METHOD AND DEVICE FOR PRODUCING ENERGY PRODUCTS BY CATALYTIC CRACKING OF A SOLID HYDROCARBON MATERIAL WITHOUT COKE FORMATION

摘要

The invention relates to a method for producing an energy product (51) by catalytic cracking of a solid hydrocarbon material without coke formation, wherein a flow of a composition, called oxygenated cracking dispersion composition (52), is formed by mixing: - a flow of a composition, called hydrocarbon dispersion composition (40), comprising: + a liquid (30, 32) that is inert in relation to catalytic cracking; + a solid material (1) in the divided state containing at least one hydrocarbon compound; + at least one catalytic cracking catalyst (10); and + at least one alkaline compound (20); and - a flow of a composition, called oxygenated composition (23), able to introduce gaseous dioxygen (O₂) into said hydrocarbon dispersion (40); then heating said oxygenated cracking dispersion (52) to a temperature between 260°C and 360°C, greater than the cracking temperature of at least one hydrocarbon compound of the solid material (1) in the divided state, by which at least one gaseous hydrocarbon (50) and gaseous dihydrogen (H₂) are formed due to the catalytic cracking, characterised in that said hydrocarbon dispersion (40) is at a temperature below the cracking temperature of each hydrocarbon compound of the solid material in the divided state when it is mixed with said oxygenated composition (23). The invention relates to such a method for producing energy products such as fuels, gaseous dihydrogen (H₂) and/or synthesis reagents of synthetic polymers. The invention also relates to a device for producing an energy product for implementing this method.
