摘要:
Organic compounds, particularly hydrocarbons, are oxidatively dehydrogenated to more unsaturated compounds by contact, under reaction conditions, with air, steam and a calcined solid catalyst composition comprising titanium, at least one component selected from the group consisting of tungsten or molybdenum, and at least one component selected from the group consisting of phosphorus, bismuth, lead, antimony or arsenic. Representative of such oxidative dehydrogenation processes is the conversion of butane to butenes and butadienes.
摘要:
A desulfurization system employing a system of fluidizable and circulatable solid particles to desulfurize a hydrocarbon-containing fluid in a fluidized bed reactor. The solid particulate system includes solid sorbent particles operable to remove sulfur from the hydrocarbon-containing fluid stream and solid catalyst particles operable to enhance the octane of the resulting desulfurized hydrocarbon-containing fluid stream. The solid particulate system can be circulated between a reactor, regenerator, and reducer, to thereby allow for substantially continuous desulfurization in the reactor.
摘要:
Particulate sorbent compositions comprising a mixture of zinc oxide, silica, alumina and a substantially reduced valence nickel are provided for the desulfurization of a feedstream of cracked-gasoline or diesel fuels in a desulfurization zone by a process which comprises the contacting of such feedstreams in a desulfurization zone followed by separation of the resulting low sulfur-containing stream and sulfurized-sorbent and thereafter regenerating and activating the separated sorbent before recycle of same to the desulfurization zone.
摘要:
A new composition of matter comprises nickel phosphate and titanium phosphate, prepared by coprecipitation. A process for removing metals from a hydrocarbon-containing feed stream, in particular a heavy oil, comprises hydrotreatment in the presence of a solid catalyst composition comprising coprecipitated nickel phosphate and titanium phosphate.
摘要:
A process for removing metals from a hydrocarbon-containing feed stream comprises hydrotreatment in the presence of a solid catalyst composition comprising aluminum phosphate, zirconium phosphate and copper phosphate (preferably coprecipitated).
摘要:
A novel cracking catalyst, a method of preparing same, and an improved hydrocarbon cracking process are provided wherein the adverse effects of metals such as nickel, vanadium, iron, copper, and cobalt on the cracking catalys are reduced by contacting the cracking catalyst with a sufficient amount of at least one indium modifier selected from the group consisting of elemental indium and indium compounds free of the element antimony.
摘要:
A used hydrocarbon cracking catalyst is treated with an antimony carbonate to passivate contaminating metals thereon, e.g., vanadium, iron and/or nickel. A process for cracking a hydrocarbon in the presence of the passivated catalyst is also disclosed.
摘要:
A used petroleum or hydrocarbon conversion or cracking catalyst having metal contaminants thereon which are leachable by water therefrom is treated with tin and/or indium and/or a compound of tin and/or a compound of indium to reduce leachability of said metal therefrom rendering the thus treated contact mass or catalyst more safe to be disposed of at a landfill.
