Abstract: A method includes maintaining a gas atmosphere at the cracking pressure through gas-exchange communication between the gas atmosphere of a cracking reactor and the gas atmosphere of a device, referred to as a thermochemical vacuum pump. A change of state of the condensation oil from the expanded gas state to the condensed liquid state is brought about in the thermochemical vacuum pump in a gas-exchange communication with the gas atmosphere of the cracking reactor, and the condensation oil is chosen so that its state-change temperature is at the level of the cracking temperature at the cracking pressure.

Abstract: A method is provided for producing at least one energy product by catalytically cracking, at a low temperature, a fragmented solid material, without the formation of coke, dioxins and/or furans. A gas atmosphere is maintained at the cracking pressure through gas-exchange communication between the gas atmosphere of the cracking reactor and the gas atmosphere of a device, referred to as a thermochemical vacuum pump, that generates a vacuum pressure formed, by way of a change of state, from an expanded gas state to a condensed liquid state. A second inert oil, referred to as a condensation oil is refluxed at a temperature higher than the evaporating temperature of the condensation oil at the cracking pressure in the thermochemical vacuum pump.

Abstract: 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.

Abstract: A method for treating garbage or waste in which the garbage or refuse is subjected to at least one compression step (14) under conditions enabling the separation thereof into a putrescible fraction (15) in the form of a moist pulp, and into a dry fraction (16) with a relative moisture of less than 20%, then the putrescible fraction is subjected to a treatment (17) by anaerobic fermentation producing a biogas (18), characterized in that the resulting dry fraction (16) is subjected to an endothermic gasification treatment (19).

Abstract: A method for treating waste involves (a) compressing the waste at a pressure of over 800 bars under conditions resulting in separation of the wet fermentable fraction and the solid combustible fraction; (b) exploiting each of these two fractions separately by means of, for the fermentable fraction, specific treatment to take advantage of its biomass nature and, for the combustible fraction, burning to produce energy. The method allows the waste to be exploited with high profitability. The invention also describes an improved press for compression in two successive phases: a precompression phase up to an intermediate pressure (200 to 300 bars) and final compression up to a final pressure of over 800 bars.
