摘要： A process and system for preparing C2 to C5 hydrocarbons includes introducing a feed stream containing hydrogen gas and a carbon-containing gas selected from carbon monoxide, carbon dioxide, and mixtures thereof into a first reaction zone, contacting the feed stream and a hybrid catalyst in the first reaction zone, introducing a reaction zone product stream into a water removal zone that is downstream from the first reaction zone, and introducing a product stream from the water removal zone into a second reaction zone, resulting in a final stream comprising C2 to C5 hydrocarbons. The hybrid catalyst includes a methanol synthesis component and a microporous solid acid component; the microporous solid acid component is a molecular sieve having 8-MR access. The water removal zone removes at least a portion of water from the reaction zone product stream.

摘要： A process for dehydrogenating alkane or alkylaromatic compounds comprising contacting the given compound and a dehydrogenation catalyst in a fluidized bed. The dehydrogenation catalyst is prepared from an at least partially deactivated platinum/gallium catalyst on an alumina-based support that is reconstituted by impregnating it with a platinum salt solution, then calcining it at a temperature from 400° C. to 1000° C., under conditions such that it has a platinum content ranging from 1 to 500 ppm, based on weight of catalyst; a gallium content ranging from 0.2 to 2.0 wt %; and a platinum to gallium ratio ranging from 1:20,000 to 1:4. It also has a Pt retention that is equal to or greater than that of a fresh catalyst being used in a same or similar catalytic process.

摘要： Increase propane dehydrogenation activity of a partially deactivated dehydrogenation catalyst by heating the partially deactivated catalyst to a temperature of at least 660° C., conditioning the heated catalyst in an oxygen-containing atmosphere and, optionally, stripping molecular oxygen from the conditioned catalyst.

摘要： The present invention is a method comprising depositing a metal oxide layer as part of the production of an optoelectrically active device and exposing the metal oxide layer to a reactive agent to form a relatively hydrophobic surface. The invention also includes device so made, preferably a photovoltaic device, which shows improved stability as compared to devices not subject to the treatment.
