The invention relates to a process for producing energy products, notably fuel, by catalytic cracking of a hydrocarbon-based solid material without coke formation, in which a cracking dispersion (40) is heated, said dispersion comprising: a solid material (1) in divided form containing at least one hydrocarbon-based compound; a liquid (30) which is inert with respect to catalytic cracking; so that the cracking dispersion (40) reaches a temperature suitable for allowing catalytic cracking of at least one hydrocarbon-based compound; characterized in that the cracking temperature is reached by mixing an amount of cracking dispersion (40) and an amount of inert liquid (30) brought to a temperature above the cracking temperature, such that the mixture formed reaches a temperature above the cracking temperature and below the temperature for formation of coke, dioxin and furan. The invention also relates to a device for performing such a process.
