A process for converting a reactant composition comprising Hand CO to a product comprising at least one aliphatic hydrocarbon having at least about 5 carbon atoms comprises: flowing the reactant composition through a microchannel reactor in contact with a Fischer-Tropsch catalyst to convert the reactant composition to the product, the microchannel reactor comprising a plurality of process microchannels containing the catalyst; transferring heat from the process microchannels to a heat exchanger; and removing the product from the microchannel reactor; the process producing at least about 0.5 gram of aliphatic hydrocarbon having at least about 5 carbon atoms per gram of catalyst per hour; the selectivity to methane in the product being less than about 25%. A supported catalyst comprises Co, and a microchannel reactor comprises at least one process microchannel and at least one adjacent heat exchange zone.

Fischer-tropsch synthesis using microchannel technology and novel catalyst and microchannel reactor

A process and system are described for the processing of gas associated with crude oil production, i.e. associated gas. A separation complex is used to separate produced fluids produced from a hydrocarbon reservoir into crude oil, liquefied petroleum gas, water, and natural gas. At least a portion of the natural gas is converted into synthesis gas in a synthesis gas generator. A combination of a synthesis gas conversion catalysts and hydroconversion catalysts are used in a synthesis gas reactor to convert the synthesis gas into a liquid effluent stream containing liquefied petroleum gas and a synthetic crude oil. The liquefied petroleum gas and synthetic crude oil from the synthesis gas reactor is sent to the separation complex. Liquefied petroleum gas is separated both from the synthetic crude oil and a natural crude oil obtained from the produced fluids. The system and process permits synthetic crude oil to be blended with the natural crude oil producing a blended stabilized crude oil having 2 wt % or more of the synthetic crude oil and with a pour point of 60&#xb0; C. or less. Use of a common facility for separation operations on the natural crude oil and synthetic crude oil thus reduces capital costs and allows converted associated gases to be shipped with the natural crude oil on a conventional crude oil tanker.

A method is disclosed for converting syngas to Fischer-Tropsch (F-T) hydrocarbon products. A synthesis gas including carbon monoxide and hydrogen gas is provided to a F-T reactor. Also, acetylene is supplied to the F-T reactor. The ratio of the volume of acetylene to the volume of synthesis gas is at least 0.01. The synthesis gas and acetylene are reacted under suitable reaction conditions and in the presence of a catalyst to produce F-T hydrocarbon products. The F-T hydrocarbon products are then recovered from the reactor. The synthesis gas and acetylene may be provided in a combined feed stream or introduced separately into the reactor. The acetylene enhanced syngas conversion in a F-T reactor results in the synthesis of F-T products which have a tighter distribution of intermediate length carbon products than do F-T products synthesized according to conventional methods.
