    摘要： A process for increasing the selectivity of an alkanolamine absorption process for selectively removing hydrogen sulfide (H2S) from a gas mixture which also contains carbon dioxide (CO2) and possibly other acidic gases such as COS, HCN, CS2 and sulfur derivatives of C1 to C4 hydrocarbons, comprises contacting the gas mixture with a liquid absorbent which is a severely sterically hindered capped alkanolamine or more basic sterically hindered secondary and tertiary amine. The improvement in selectivity is achieved at the high(er) pressures, typically least about 10 bara at conditions nearing the H2S/CO2 equilibrium at which CO2 begins to displace absorbed hydrosulfide species from the absorbent solution.

    摘要： Promoter amines are used to enhance CO2 uptake by sterically hindered or tertiary amines. The promoter amines can be cyclic amines, including aromatic cyclic amines or bridged cyclic amines. The combination of a promoter amine plus a sterically hindered or tertiary amines allows for improved uptake kinetics while reducing or minimizing the amount of formation of carbamate salts. The promoted sterically hindered or tertiary amines can be used as part of a CO2 capture and release system that involves a phase transition from a solution of amine-CO2 products to a slurry of amine-CO2 precipitate solids.

    摘要： The feeding of coal slurries into a gasifier for the production of synthesis gas is improved by modifying the rheological properties of the coal particles so that conventional liquid transfer equipment can be used in the feed transfer process to the gasifier. The coal particle surface modification is accomplished by adsorbing asphaltenes derived from petroleum onto the surfaces of coal particles prior to and/or during contact with the slurry liquid. The coal particles with their surfaces thus modified exhibit lower particle-particle interaction in the liquid slurries to form a shear independent Newtonian fluid or a weakly shear thickening pseudoplastic fluid. The rheological properties of the slurries permit them to be transported reliably into a pressurized, entrained feed gasifier vessel using convention slurry pumps with a low potential expenditure of energy.

    摘要翻译： 通过改变煤粒子的流变性能，可以将煤浆料送入用于生产合成气体的气化器中，从而可以将传统的液体输送设备用于进料到气化器的进料转移过程。 煤颗粒表面改性是通过在与浆料液体接触之前和/或与其接触期间将来自石油的沥青质吸附在煤颗粒表面上来实现的。 具有如此改性的其表面的煤颗粒在液体浆料中表现出较低的颗粒 - 颗粒相互作用，以形成剪切无关的牛顿流体或弱剪切增稠假塑性流体。 浆料的流变性使其能够使用具有低潜在能量消耗的常规浆料泵将其可靠地运输到加压夹带的进料气化器容器中。
