Method of producing gaseous products using a downflow reactor

摘要

Reactor systems and methods are provided for the catalytic conversion of liquid feedstocks to synthesis gases and other noncondensable gaseous products. The reactor systems include a heat exchange reactor configured to allow the liquid feedstock and gas product to flow concurrently in a downflow direction. The reactor systems and methods are particularly useful for producing hydrogen and light hydrocarbons from biomass-derived oxygenated hydrocarbons using aqueous phase reforming. The generated gases may find used as a fuel source for energy generation via PEM fuel cells, solid-oxide fuel cells, internal combustion engines, or gas turbine gensets, or used in other chemical processes to produce additional products. The gaseous products may also be collected for later use or distribution.

主权项

1. A method for the manufacture of noncondensable gas, the method comprising:
reacting a liquid feedstock comprising water and at least one C2+ water soluble oxygenated hydrocarbon using a heterogeneous catalyst comprising one or more Group VIIIB metals, at a temperature between about 80° C. to 300° C. and a reaction pressure suitable to produce the noncondensable gas and an effluent, wherein a pressure gradient provides concurrent downflow of the liquid feedstock, effluent and noncondensable gas.
