    摘要: A process for the hydroconversion of heavy oil products includes the following steps where heavy oil products and hydrogen are supplied to a slurry hydroconversion section having a molybdenum-based catalyst: separating the reaction effluent into a vapour phase and a slurry phase; and sending the slurry phase to a separation section having the function of separating the Vacuum Gas Oil, Heavy Vacuum Gas Oil, Light Vacuum Gas Oil, and Atmospheric Gas Oil fractions, from a stream of heavy organic products which contains asphaltenes, unconverted feed, catalyst, and solid formed during the hydroconversion reaction. This stream is partly sent to the reaction section and partly forms a purge stream, which is heated and made fluid between 185° C.-220° C., and subjected to a static settling unit up to at least 100° C. From the settling unit two new products, clarified component and cake, are obtained. The clarified component is recycled to the hydroconversion reaction section.

    摘要: A process for producing syngas and olefins includes the steps of feeding a catalytic partial oxidation (CPO) reactant mixture having oxygen, first hydrocarbons, and optionally steam to a CPO reaction zone having a CPO catalyst such that at least a portion of the CPO reactant mixture reacts, via an exothermic CPO reaction, to produce syngas having hydrogen (H2), carbon monoxide (CO), carbon dioxide (CO2), water, and unreacted first hydrocarbons. The syngas is characterized by a molar ratio M defined as (H2−CO2)/(CO+CO2). The method further includes feeding a cracking zone feed having second hydrocarbons to a cracking zone such that at least a portion of the second hydrocarbons undergoes an endothermic cracking reaction to produce a cracking zone product stream having olefins, hydrogen, and unreacted second hydrocarbons; and cooling the CPO reaction zone by heating the cracking zone while cooling the CPO reaction zone via heat transfer between the CPO reaction zone and the cracking zone.

    摘要: A process for producing syngas and olefins including the steps of feeding a catalytic partial oxidation (CPO) reactant mixture (oxygen, first hydrocarbons, steam) to a CPO reactor (CPO catalyst); wherein the CPO reactant mixture reacts, via CPO reaction, in CPO reactor to produce a CPO reactor effluent (H2, CO, CO2, water, unreacted first hydrocarbons). The process further includes feeding a cracking unit feed (second hydrocarbons) to a cracking unit to produce a cracking unit product (olefins), a hydrogen-rich stream (hydrogen, CH4), and a hydrocarbon recovery stream (C4+ hydrocarbons); wherein the first and the second hydrocarbons are the same or different; recovering a hydrogen-enriched stream (hydrogen) and a hydrocarbon-enriched stream (CH4) from the hydrogen-rich stream; and contacting the CPO reactor effluent with the hydrogen-enriched stream to yield hydrogen-enriched syngas, and wherein the M ratio ((H2—CO2)/(CO+CO2)) of the hydrogen-enriched syngas is greater than the M ratio of the CPO reactor effluent.

    摘要: There is a process for the selective recovery of transition metals from an organic stream containing transition metals. The organic stream and possibly a first extractor if solid, are melted up to the liquid state. The extractor consists of an ionic liquid or a mixture of two or more ionic liquids and the ionic liquid contains an ammonium salt as cation and as anion an anion with chelating properties. A melted organic stream and a first extractor, optionally melted, are fed to a first liquid-liquid extraction unit working at a temperature of at least 150° C. where the liquid-liquid extraction is carried out obtaining a liquid mixture containing an ionic liquid, or a mixture of two or more ionic liquids, and metals. After extraction, the liquid mixture is cooled at a temperature between 0° C. and 70° C. and becomes biphasic; then the cooled mixture is sent to a first separation unit, to separate a liquid phase that contains ionic liquids and metals, and a metal-depleted solid phase. After the first separation, the separated metal-depleted solid phase is optionally sent to a washing unit to which a solvent is fed, so as to eliminate the residual ionic liquid by transferring it into the solvent and obtaining a metal-depleted solid phase. Then the separate liquid phase containing ionic liquids and metals is sent into a liquid-liquid precipitation and separation unit, adding a counter-solvent, thereby obtaining a solid phase containing the metals and a liquid stream containing counter-solvent and ionic liquids.
