Process and device for producing energy products by catalytic cracking of a hydrocarbon-based solid material without coke formation

A process for producing energy products by catalytic cracking of a hydrocarbon solid material, in which a dispersion, named cracking dispersion, is heated, said dispersion comprising:

• a solid material in divided form containing at least one hydrocarbon-based compound;
• at least one catalytic cracking catalyst;
• at least one alkaline compound;
• and
• an inert liquid with respect to catalytic cracking;
• such that said cracking dispersion reaches a temperature, named cracking temperature, between 240° C. and 340° C. which is suitable to allow catalytic cracking of the at least one hydrocarbon-based compound of said cracking dispersion, leading to a production of hydrocarbons, named short-chain hydrocarbons, of lower molecular mass than said hydrocarbon-based compound;
• wherein said cracking temperature is reached by mixing an amount of said cracking dispersion and an amount of said inert liquid which is substantially free of solid material in divided form and of catalyst, the inert liquid being brought to a temperature below 360° C. and above said cracking temperature, said mixing being performed such that the mixture of said cracking dispersion and of an amount of said inert liquid that is substantially free of solid material in divided state and substantially free of catalytic cracking catalyst, reaches a temperature at least equal to said cracking temperature and below a temperature sufficient for coke formation under conditions of said catalytic cracking of the hydrocarbon-based compound, and in that an amount of an oxygenated gaseous composition capable of bringing about an exothermic reaction with at least a portion of dihydrogen produced during the catalytic cracking is supplied to said cracking dispersion at said cracking temperature.
