摘要： A process and apparatus are disclosed for the operation of a compact water gas shift reactor for use in conjunction with fuel cell to generate electric power from a feed stream comprising a hydrocarbon or an alcohol. The fuel cell comprises a proton exchange membrane which produces electric power from a hydrogen product stream which comprises essentially no carbon monoxide. The hydrogen product stream may produced from the feed stream in a steam reforming of autothermal reforming zone. The compact water gas shift reactor comprises a vertically aligned vessel having a top end, a bottom end opposite, which defines an interior space. The interior space contains a first water spray zone for contacting a reforming effluent stream comprising hydrogen with a first water stream. A first dispersion zone is disposed below the first water spray zone and above a high temperature shift zone. The high temperature shift zone contains a high temperature shift catalyst to produce a high temperature shift effluent stream. A second water spray zone is disposed below the high temperature shift zone and above a second dispersion zone. A low temperature shift zone is disposed below the second dispersion zone. The low temperature shift zone contains a low temperature shift catalyst to produce a water saturated hydrogen product stream which comprises less than 50 ppm-mol carbon monoxide. The water dispersion zones simplify the overall shift reaction zone and provide protection for the shift catalysts from temperature shock.

摘要： A process and apparatus are disclosed for the operation of a fuel cell to generate electric power from a feed stream comprising a hydrocarbon or an alcohol. The fuel cell comprises a proton exchange membrane which produces electric power from a hydrogen product stream which comprises essentially no carbon monoxide. The hydrogen product stream is produced from the feed stream in a novel steam reforming zone containing a steam reforming catalyst disposed in a bell-shaped catalyst zone. The bell-shaped catalyst zone is disposed over a combustion zone such that the exhaust gas from the combustion flows around the bell-shaped catalyst zone to heat the catalyst from the inside and the outside of the catalyst zone. Furthermore, the bell-shaped catalyst zone maintains a high inlet and a high outlet temperature to avoid methane slippage in the steam reforming zone. Heat for the steam reforming zone is provided by a fuel stream and at least a portion of the anode waste gas stream from the fuel cell.

摘要： A process and system for separating and saturating benzene from a reforming reactor effluent begins with introducing the reforming reactor effluent to a combined stabilizer and naphtha splitter. An overhead stream comprising light ends, a sidecut stream comprising C4− C5 compounds, a bottoms stream comprising C7+ compounds and a heart cut stream comprising C4, C5, C6 compounds including benzene are all removed from the combined stabilizer and naphtha splitter. The heart cut stream is introduced to a side stripper to produce a side stripper overhead stream reduced in benzene and a side stripper bottoms stream enriched in benzene. At least a portion of the side stripper bottoms stream enriched in benzene is introduced into a hydrogenation zone to saturate benzene and generate a hydrogenation zone effluent reduced in benzene. The side stripper overhead stream may be recycled to the combined stabilizer and naphtha splitter.
