Patent ID: 8188153

Claim:
A process for conducting a Fischer-Tropsch reaction in a microchannel reactor, the microchannel reactor comprising a plurality of process microchannels and a plurality of heat exchange channels, the heat exchange channels extending lengthwise at right angles relative to the lengthwise direction of the process microchannels, the process comprising: flowing reactants comprising CO and H 2 in the process microchannels in contact with a Fischer-Tropsch catalyst to form a reaction product comprising one or more aliphatic hydrocarbons, the catalyst comprising cobalt supported on an alumina support and being in the form of particulate solids, the cobalt loading being at least about 28% by weight; exchanging heat between the process microchannels and a heat exchange fluid in the heat exchange channels, the heat exchange fluid undergoing a phase change in the heat exchange channels.
