Abstract: A method for producing methanol includes feeding a synthesis gas stream to a methanol production assembly; feeding an off gas stream including hydrogen to the methanol production assembly; feeding a CO2 stream to the methanol production assembly; and reacting the synthesis gas stream and the CO2 stream in the methanol production assembly to produce methanol, wherein the method further includes reacting the off gas stream with the synthesis gas stream and the CO2 stream in the methanol production assembly to produce methanol, or feeding a reforming feed stream and the off gas stream including hydrogen to a reforming portion of the methanol production assembly to form the synthesis gas stream.

Abstract: Methods to produce propylene oxide are described. One method can include providing a propene feedstream, an oxygen feed stream and, optionally, a hydrogen feed stream to a reaction zone, and maintaining, in a reaction zone during the reaction, at least 50 vol. % propene and 1 to 15 vol. % O2 by gradually introducing a feed stream that includes the O2 over the length of the catalytic bed or the length of the reaction zone and/or a feed stream that includes the H2 over the length of the catalytic bed or the length of the reaction zone.
