摘要： A process for the in situ attrition and break up of an agglomerating, or agglomerated catalyst to maintain and control the fluidization characteristics of a bed wherein low molecular weight hydrocarbons, oxygen and steam are contacted with the bed to produce hydrogen and carbon monoxide via both partial oxidation and steam reforming reactions. The feeds are injected into the reaction zone with mechanical energy input sufficient to balance the intrinsic rate of agglomeration by fracturing and breaking apart in situ the agglomerated catalyst to maintain the fluidization characteristics of the bed throughout the cycle of operation.

摘要： A process for the production of syn gas (hydrogen and carbon monoxide) by reaction at high temperature between low molecular weight hydrocarbons, steam and oxygen in an impurities-containing refractory lined reaction zone. The lined reaction zone is pretreated with steam, or with steam and a reducing gas, e.g. a mixture of steam and hydrogen to leach out, react with, and transport the impurities, i.e., the reaction products of silica, or silica plus phosphorus or sulfur, or silica plus phosphorus and sulfur, from the reaction zone. Steam alone may be used to leach out, convert the silica to gaseous silicic acid, and remove same from the reaction zone; and then the hydrocarbons, steam and oxygen feeds are introduced into the reaction zone to produce syn gas.

摘要： A particulate, precalcined low silica content zirconia, especially one stabilized with yttria, is useful as a catalyst support or as a heat transfer solids component for conducting chemical reactions at high temperature, in oxidizing, reducing or hydrothermal conditions, especially in syn gas operations. An admixture of precalcined particulate low silica content zirconia, particularly a low silica content yttria-stabilized zirconia, is employed in a preferred embodiment as a heat transfer solid, in concentrations ranging generally from about 10 wt. % to about 99.9 wt. %, with a particulate catalyst, notably a nickel-on-alumina catalyst, in concentration ranging generally from about 0.1 wt. % to about 90 wt. %. Such an admixture provides a particularly useful catalytic contact mass in high temperature oxidizing, reducing and hydrothermal environments, notably in conducting synthesis gas generation operations. This type of bed promotes continuous, highly efficient heat and mass transfer within the reacting gas phase. The presence of the heat transfer solid as a bed component maintains excellent bed fluidization characteristics, suppressing the normal tendency of the catalyst to sinter or agglomerate; tendencies which promote defluidization of the bed. Moreover, the heat transfer particles of the bed are highly attrition resistant, and are chemically compatible with the catalyst particles of the admixture.

摘要： A method for removing an acidic component from a gaseous mixture by contacting the gaseous mixture in an absorber with an absorbing solution which removes substantial quantities of the acidic component. The gaseous mixture is then passed through an adsorption zone containing an adsorbent which removes additional quantities of the acidic component. The adsorbent is regenerated by passing regenerating solution through the adsorption zone. In a preferred embodiment, the composition of the regenerating and absorbing solutions are substantially the same and include an amine. This solution may be passed through the adsorption zone to regenerate the adsorbent and then into the absorber to remove acidic components from the gaseous mixture therein.

摘要： An improved process for removing carbon dioxide from a gaseous feed including carbon dioxide is described. The carbon dioxide is removed from a gaseous feed by contacting the feed in a contacting zone with a scrubbing solution comprising a sterically hindered amine and an alkali metal salt or alkali metal hydroxide, which at least partially absorbs the carbon dioxide. The scrubbing solution subsequently is desorbed and separated into a two-phase liquid system, an upper phase relatively rich in sterically hindered amine and having a relatively high ratio of alkali bicarbonate to alkali carbonate and a lower liquid phase having a relatively low ratio of alkali bicarbonate to alkali carbonate. The lower liquid phase is returned to the contacting zone at a location above that at which the upper liquid phase is returned to the contacting zone.

摘要： Hydrogen sulfide and its precursors can be selectively sorbed from gas streams containing the same by contacting the gas stream at elevated temperatures with a regenerable sorbent comprising a steam-treated support composited with a rare earth metal component. Presteaming the support lowers the amount of rare earth metal component needed to achieve a given activity level for hydrogen sulfide removal. Subsequent to sorption, the sorbent composite may be desorbed and regenerated by treatment with steam (desorption) and an oxidizing gas (regeneration). The sorbent capacity may be increased by the use of alkali or alkaline earth metal components as promoters. A preferred sorbent comprises lanthanum composited with presteamed alumina.
