摘要： The present disclosure provides a method for regulating a quality of an oil derived from plastic wastes by supercritical hydrothermal liquefaction, including catalyst synthesis, calcination, and supercritical hydrothermal liquefaction. In the present disclosure, a catalyst is prepared by the method, and then applied in regulating the quality of the oil derived from plastic wastes by supercritical hydrothermal liquefaction. This not only reduces cost, but also optimizes a reaction process, such that plastics can be recycled as resources, thereby reducing the carbon emissions and promoting the development of circular economy. The method has strong practicability and functionality, and can be widely used in the technical fields of harmless treatment and resource utilization of plastic waste.

A method of producing a catalyst support, the method including mixing SiC particles of 0.1-20 microns, SiO2 and carbonaceous materials to form an extrusion, under inert atmospheres, heating the extrusion at temperatures of greater than 1400° C., and removing residual carbon from the heated support under temperatures below 1000° C. A catalyst on a carrier, comprising a carrier support having at least about 95% SiC, with a silver solution impregnated thereon comprising silver oxide, ethylenediamine, oxalic acid, monoethanolamine and cesium hydroxide. A process for oxidation reactions (e.g., for the production of ethylene oxide, or oxidation reactions using propane or methane), or for endothermic reactions (e.g., dehydrogenation of paraffins, of ethyl benzene, or cracking and hydrocracking hydrocarbons).

摘要： A process for treating a feed oil in the presence of in situ produced catalyst particles comprising the steps of mixing the supercritical water feed with the pressurized precursor solution in a catalyst mixer to produce a supercritical water stream; withdrawing the supercritical water stream to a process line, where the catalyst precursor is converted to catalyst particles in the process line; mixing the supercritical water stream and the hot oil stream in the mixer to produce a mixed stream; introducing the mixed stream to a reactor; processing the heavy oil in the reactor in the presence of the catalyst particles to produce a reactor effluent; reducing a temperature of the reactor effluent to produce a cooled effluent; reducing a pressure of the cooled effluent to produce a depressurized effluent; and separating the depressurized effluent to produce a product gas, a product oil, and a product water.

摘要： Processes for upgrading a heavy oil or heavy oil-derived feedstock in presence of an ionic liquid are described, and can improve the heavy oil or heavy oil-derived properties such as viscosity and composition, and reduced contaminant content, such as a reduced Total Acid Number (TAN) and a reduced heavy metal content. Processes for upgrading heavy oil or heavy oil-derived in presence of an ionic liquid can include a catalytic cracking treatment carried out under catalytic cracking conditions, and/or a non-catalytic treatment, as well as various separation steps to separate the ionic liquid or a diluent if present in the feedstock. The ionic liquids that can be used in the context of the processes described herein include ionic liquids that are feed-miscible or feed-immiscible.

摘要： Processes and catalyst systems are disclosed for performing Fischer-Tropsch (FT) synthesis to produce C4+ hydrocarbons, such as gasoline boiling-range hydrocarbons and/or diesel boiling-range hydrocarbons. Advantageously, catalyst systems described herein have additional activity (beyond FT activity) for in situ hydroisomerization and/or hydrocracking of wax that is generated according to the distribution of hydrocarbons obtained from the FT synthesis reaction. This not only improves the yield of hydrocarbons (e.g., C4-19 hydrocarbons) that are useful for transportation fuels, but also allows for alternative reactor types, such as a fluidized bed reactor.

摘要： According to at least one aspect of the present disclosure, a method for processing a heavy oil includes introducing the heavy oil to a hydroprocessing unit, the hydroprocessing unit being operable to hydroprocess the heavy oil to form a hydroprocessed effluent by contacting the heavy oil feed with an HDM catalyst, an HDS catalyst, and an HDA catalyst. The hydroprocessed effluent is passed directly to a HS-FCC unit, the HS-FCC unit being operable to crack the hydroprocessed effluent to form a cracked effluent comprising at least one product. The cracked effluent is passed out of the HS-FCC unit. The heavy oil has an API gravity of from 25 degrees to 50 degrees and at least 20 wt. % of the hydroprocessed effluent passed to the HS-FCC unit has a boiling point less than 225 degrees ° C.
