    Abstract: Methods are provided for removing CO2 and/or H2S from a gas phase stream, such as a refinery flue gas stream, a coal-fired or petroleum-burning power plant, or a natural gas stream. A gas phase stream containing CO2 and/or H2S can be contacted under effective conditions with an aqueous slurry of supported amine particles. The CO2 and/or H2S can react with the supported amines to form bicarbonates, carbonates, carbamates, sulfide salts, or other species. Because the amine is part of, bonded to, or otherwise supported on a particulate substrate, the reaction product from the amine reaction can also remain bound to the particle. After reacting supported amines with CO2 and/or H2S captured from a gas stream, the supported amines particles can be separated from the aqueous slurry environment for regeneration of the supported amine and release of the CO2 and/or H2S.

    Abstract: A process for dewaxing waxy hydrocarbonaceous materials, such as hydrocarbon fuel and lubricating oil fractions to reduce their cloud and pour points comprises reacting the material with hydrogen in the presence of a dewaxing catalyst comprising at least one metal catalytic component and ferrierite in which at least a portion of its cation exchange positions are occupied by one or more trivalent rare earth metal cations. The rare earth ion exchanged ferrierite catalyst has good selectivity for lubricating oil production, particularly when dewaxing a Fischer-Tropsch wax hydroisomerate. Preferably at least 10% and more preferably at least 15% of the ferreirite cation exchange capacity is occupied by one or more trivalent rare earth metal cations.
