摘要： The present disclosure provides systems and methods for regenerating a hydrogenation catalyst with reduced water consumption and/or shortened overall regeneration time. The method can include contacting a fouled hydrogenation catalyst with a first flushing medium comprising water and a gaseous phase comprising oxygen and optionally a second flushing medium comprising water and a gaseous phase comprising at least 90% nitrogen by volume. The method can further include treating the effluents of the flushing mediums by ion exchange resin to remove impurities in the effluents.

摘要： Paraffin compositions including mainly even carbon number paraffins, and a method for manufacturing the same, is disclosed herein. In one embodiment, the method involves contacting naturally occurring fatty acid/glycerides with hydrogen in a slurry bubble column reactor containing bimetallic catalysts with equivalent particle diameters from about 10 to about 400 micron. The even carbon number compositions are particularly useful as phase change material.

摘要： Processes for producing olefins include integration of steam cracking with a dual catalyst metathesis process. The processes include steam cracking a hydrocarbon feed to form a cracking reaction effluent containing butenes, separating the cracking reaction effluent to produce a cracking C4 effluent including normal butenes, isobutene, and 1,3-butadiene, subjecting the cracking C4 effluent to selective hydrogenation to convert 1,3-butadiene in the cracking C4 effluent to normal butenes, removing isobutene from a hydrogenation effluent to produce a metathesis feed containing normal butenes, and contacting the metathesis feed with a metathesis catalyst and a cracking catalyst directly downstream of the metathesis catalyst to produce a metathesis reaction effluent. Contacting with the metathesis catalyst causes metathesis of normal butenes to produce ethylene, propene, and C5+ olefins, and contacting with the cracking catalyst causes C5+ olefins produced through metathesis to undergo cracking reactions to produce additional propene, ethylene, or both.

摘要： A fluidized bed regenerator, a device for preparing low-carbon olefins, and a use thereof are provided. The fluidized bed regenerator includes a second activation zone, a first activation zone, and a gas-solid separation zone from bottom to top; the second activation zone axially communicates with the gas-solid separation zone; the first activation zone is arranged on a periphery of a junction between the second activation zone and the gas-solid separation zone; the first activation zone is an annular cavity; n baffles are radially arranged in the first activation zone, and the n baffles divide the first activation zone into n first activation zone subzones; and a catalyst circulation hole is formed in each of n−1 of the baffles such that a catalyst entering the first activation zone flows in an annular direction.

摘要： The present invention is directed to a method of preparing a molecular sieve of SWY framework type, denominated STA-30. STA-30 is synthesized using 1,4-diazabicyclo[2.2.2]octane, 1-azabicyclo[2.2.2]octane derivates and combinations thereof as structure directing agents. The resulting molecular sieve is useful as catalysts, particularly when used in combination with exchanged transition metal(s) for the Selective Catalytic Reduction (SCR) of NO
