摘要:
The present invention involves a catalytic process for purifying a gas stream comprising purifying the gas stream at a temperature from about 250° to 550° C. by removing sulfur compounds and including a gas shift reaction to convert carbon monoxide to carbon dioxide to produce a partially purified gas stream. The warm gas stream purification involves COS hydrolysis and hydrogenation to H2S, the removal of H2S, and a CO gas shift to convert CO to CO2 to produce a partially purified stream. Then the carbon dioxide and other impurities are removed from the partially purified gas stream.

摘要:
Improved processing of an oxygenate-containing feedstock for increased production or yield of light olefins. Such processing involves oxygenate conversion to olefins and subsequent cracking of heavier olefins wherein at least a portion of the products from each of the reactors is elevated in pressure, using a common compressor, prior to being routed to a common product fractionation and recovery section. In one particular embodiment, the cracked product gas can be treated to remove acid gas therefrom. In another embodiment, the olefin cracking reactor is a moving bed reactor.

摘要:
A process for the simultaneous hydroconversion of a first feedstock comprising unsaturated, halogenated organic compounds and a second feedstock comprising saturated, halogenated organic compounds which process comprises: (a) reacting the first feedstock comprising unsaturated, halogenated organic compounds with hydrogen in a first hydrogenation reaction zone operated at hydrogenation conditions selected to minimize the polymerization of unsaturated organic compounds and to produce a first hydrogenated stream comprising hydrocarbonaceous compounds; (b) reacting at least a portion of the first hydrogenated stream comprising hydrocarbonaceous compounds and the second feedstock comprising saturated, halogenated organic compounds with hydrogen in a second hydrogenated reaction zone operated at hydrogenation conditions selected to produce a second hydrogenated stream comprising hydrocarbonaceous compounds and to generate at least one water-soluble inorganic halide compound; (c) contacting the resulting effluent from the second hydrogenation zone containing hydrogenated hydrocarbonaceous compounds and at least one water-soluble inorganic halide compound with a halide-lean aqueous scrubbing solution; and (d) introducing a resulting admixture of the effluent from the second hydrogenation zone and the halide-lean aqueous scrubbing solution into a separation zone to provide a hydrogen-rich gaseous stream, a third hydrogenated stream comprising hydrocarbonaceous compounds and a halide-rich aqueous scrubbing solution containing at least a portion of the water-soluble inorganic halide compound.
摘要:
A process for the production of hydrogenated, distillable hydrocarbonaceous product from a feed comprising hydrocarbonaceous compounds and having a non-distillable component, and a feed comprising halogenated organic compounds by means of contacting the feed comprising hydrocarbonaceous compounds and having a non-distillable component with a hot hydrogen-rich gaseous stream to increase the temperature of this feed stream to vaporize at least a portion of the distillable hydrocarbonaceous compounds thereby producing a distillable hydrocarbonaceous product which is immediately hydrogenated in an integrated hydrogenation zone. The feed comprising halogenated organic compounds is contacted in a second hydrogenated hydrocarbonaceous product and at least one water-soluble inorganic halide compound.

A process for treating a temperature-sensitive hydrocarbonaceous stream containing a non-distillable component to produce a hydrogenated distillable hydrocarbonaceous product while minimizing thermal degradation of the hydrocarbonaceous stream which process comprises the steps of: (a) contacting the hydrocarbonaceous stream with a first hydrogen-rich gaseous stream having a temperature greater than the hydrocarbonaceous stream in a flash zone at flash conditions thereby increasing the temperature of the hydrocarbonaceous stream and vaporizing at least a portion thereof to provide a hydrocarbonaceous vapor stream comprising hydrogen and a heavy stream comprising the non-distillable component; (b) contacting the hydrocarbonaceous vapor stream comprising hydrogen with a hydrogenation catalyst in a hydrogenation reaction zone at hydrogenation conditions to increase the hydrogen content of the hydrocarbonaceous compounds contained in the hydrocarbonaceous vapor stream; (c) condensing at least a portion of the resulting effluent from the hydrogenation reaction zone to provide a second hydrogen-rich gaseous stream and a liquid stream comprising hydrogenated distillable hydrocarbonaceous compounds; (d) recovering a hydrogenated distillable hydrocarbonaceous product from the liquid stream comprising hydrogenated distillable hydrocarbonaceous compounds; and (e) reacting at least a portion of the heavy stream comprising the non-distillable component recovered from step (a) in a thermal coking zone at thermal coking conditions to provide a thermal coking zone effluent.
