摘要:
A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.

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.

A process for removing a nitrogen compound from a fuel feed, such as vacuum gas oil or diesel fuel, wherein the process includes contacting the fuel feed comprising the nitrogen compound with a fuel-immiscible caprolactamium ionic liquid to produce a fuel and fuel-immiscible caprolactamium ionic liquid mixture, and separating the mixture to produce a vacuum gas oil or a diesel effluent having a reduced nitrogen content relative to the vacuum gas oil or diesel feed. The invention provides an alternate use for caprolactamium ionic liquid that is produced in large quantities for the manufacture of caprolactam.

A process for de-acidifying a hydrocarbon feed includes contacting the hydrocarbon feed containing an organic acid with a feed-immiscible phosphonium ionic liquid to produce a hydrocarbon and feed-immiscible phosphonium ionic liquid mixture; and separating the mixture to produce a hydrocarbon effluent having a reduced organic acid content relative to the hydrocarbon feed. Optionally, a de-emulsifier is added to at least one of the contacting and separating steps.

A process for removing a metal from a crude oil includes contacting the crude oil containing the metal with a crude-immiscible ionic liquid to produce a crude oil and crude-immiscible ionic liquid mixture, and separating the mixture to produce a crude oil effluent having a reduced metal content relative to the crude oil feed. Optionally, a de-emulsifier is added to at least one of the contacting and separating steps.
摘要:
A process for removing a sulfur compound from a vacuum gas oil feed includes contacting the vacuum gas oil feed comprising the sulfur compound with a VGO-immiscible ionic liquid to produce a vacuum gas oil and VGO-immiscible ionic liquid mixture, and separating the mixture to produce a vacuum gas oil effluent having a reduced sulfur content relative to the vacuum gas oil feed.

The present invention involves a process and materials for desulfurization of a gaseous stream comprising contacting the gas stream with a manganese aluminate catalyst. The manganese aluminate catalyst is preferably selected from the group consisting of Mn2xAl2O2x+3, Mn(2−y)(MnO)yAl2O(5−y), Mn(4−y)(MnO)yAl2O(7−y), Mn(6−y)(MnO)yAl2O(9−y), Mn(1−z)(MnO)zAlO(3−z) and intermediates thereof, wherein x≧0.5, 0≦y≦2 and 0≦z≦1. Preferably, x is between 1 and 3.

One exemplary embodiment can be an apparatus for treating a hydrocarbon stream having one or more compounds with a boiling point of about 140-about 450° C. The apparatus can include an extraction zone and a regeneration zone. The extraction zone can include at least one settler. Each settler can have a height and a length. Typically the length is greater than the height. Also, the settler can form a boot, which can be adapted to receive a feed at one end. The regeneration zone may include a regenerator for an ionic liquid. The regenerator can include a column adapted to provide a regenerated ionic liquid to the extraction zone.
