METHOD OF THERMAL DECOMPOSITION OF ORGANIC SUBSTANCE (AS AMENDED)
Provided is a thermal decomposition method that allows efficient thermal decomposition of an organic substance such as a plastic to produce gas and oil with high heating value and with which a large amount of the organic substance can be processed. The method includes mixing the organic substance with an organic substance decomposition catalyst, forming the mixture to produce a composite agglomerated material, and thermally decomposing the organic substance by placing the composite agglomerated material in a thermal decomposition furnace. The maximum catalytic effect can be obtained since the organic substance and the catalyst are close to each other in the composite agglomerated material. Since the catalyst has thermal conductivity higher than that of the organic substance, the temperature rising rate of the organic substance can be increased. As a result, the efficiency of thermal decomposition of the organic substance by the catalyst can be improved, and the rate of thermal decomposition of the organic substance can be effectively increased.
Process and device for producing energy products by catalytic cracking of a hydrocarbon-based solid material without coke formation
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.
Simultaneous pretreatment method of heavy hydrocarbon distillate and lignocellulosic biomass using solvent
A method of reforming a heavy hydrocarbon distillate, which includes treating a heavy hydrocarbon distillate and a lignocellulosic biomass with a solvent, is provided. The method can be useful in maximizing conversion of the heavy hydrocarbon distillate into higher value-added distillate, for example, naphtha and a middle distillate, and allowing a sulfur compound produced by the decomposition of a heavy hydrocarbon distillate to catalyze pretreatment of the lignocellulosic biomass. Also, oxygen, hydroxymethylfurfural (HMF), levulinic acid, formic acid, and sulfuric acid produced by decomposition of the lignocellulosic biomass can catalyze decomposition of a heavy hydrocarbon distillate and lignocellulosic biomass, thereby activating decomposition of a heavy hydrocarbon distillate.
Increasing stability of a pyrolysis product
The present disclosure relates generally to novel biomass pyrolysis processes and systems that decrease entrainment of char and other contaminants with the pyrolysis vapors as a direct consequence of the biomass feedstock comprising particles that are larger than a defined minimum diameter. The biomass feedstock may optionally be compressed to form feedstock pellets that are larger than a defined minimum diameter.

PROCESS FOR POLYMER MIXTURE HYDROCONVERSION
There is a process for the hydroconversion of mixtures of polymers or plastics which comprises the pre-treatment of the mixtures through methods selected from mechanical methods, chemical methods, thermal methods, or combinations thereof forming a pre-treated charge. The pre-treated charge is mixed with a hydrocarbon vacuum residue, optionally pre-heated, to form a reactant mixture. The reactant mixture is fed to a hydroconversion section in slurry phase, together with a catalyst precursor containing Molybdenum, and a stream containing hydrogen, forming a reaction effluent. The effluent is separated into at least one high-pressure and high-temperature separator in a vapour phase and a slurry phase. The separate vapour phase is sent to a gas treatment section with the function of separating a liquid fraction from the gas containing hydrogen and hydrocarbon gases having from 1 to 4 carbon atoms; said liquid fraction comprising naphtha, atmospheric gas oil (AGO), vacuum gas oil (VGO). The slurry phase is then sent to a separation section that has the function of separating the fractions of the Vacuum Gas Oil (VGO), Heavy Vacuum Gas Oil (HVGO), Light Vacuum Gas Oil (LVGO), Atmospheric Gas Oil (AGO), from a stream of heavy organic products which contains asphaltenes, unconverted charge, catalyst and solid formed during the hydroconversion reaction. This stream of heavy organic products is partly recirculated to the hydroconversion section and partly forms a purge stream.
METHOD FOR MODIFYING BIOBASED MATERIALS AND THE RESULTING COMPOSITIONS
A method of modifying a biobased feedstock derived from agricultural resources and specifically from the non-distillate products of fermentation-derived renewable fuel and distilled spirit processes. The pyrolytic modification of biobased feedstocks results in materials that are thermally stable and better suited for subsequent melt processing in a polymer matrix.
PRODUCTION OF LINEAR OLEFINS FROM HEAVY OIL
A process for producing olefins comprising the steps of separating the liquid oil in the fractionator to produce a light oil product; separating the light oil product in the extractor to produce a paraffin fraction stream; increasing a pressure of the paraffin fraction stream in a paraffin pump to produce a pressurized paraffin stream; mixing the pressurized paraffin stream with a pressurized water feed in the water mixer to produce a paraffin-containing water stream; heating the paraffin-containing water stream in the water heater to produce a hot paraffin-water stream, wherein a temperature of the hot paraffin-water stream is greater than 450 deg C, wherein the short chain paraffins are operable to crack at the temperature of the hot paraffin-water stream; mixing the hot paraffin-water stream and the hot feedstock in the feed mixer to produce a mixed feed stream; and introducing the mixed feed stream to the supercritical unit.
