摘要： Light hydrocarbons, e.g., methane are converted to synthesis gas at elevated temperatures and pressures in the presence of a particulate catalyst, e.g., Ni/Al.sub.2 O.sub.3. The conversion of feed to synthesis gas is preserved by rapidly cooling the reaction production to a temperature below that which favors the back reaction of carbon monoxide and hydrogen to form methane.

摘要： An alkaline absorbent composition comprising a severely hindered amino compound and an amine salt is provided. A process for the removal of H.sub.2 S from fluid mixtures using this absorbent composition to produce a very low level of H.sub.2 S in the treated fluid is also provided. The process is also suited for the selective removal of H.sub.2 S from fluid mixtures comprising H.sub.2 S and CO.sub.2.

摘要： A cyclic urea reaction product forms as a by-product of a hindered amine acid gas scrubbing process and results in an ultimate buildup of the material in the circulating amine scrubbing solution. The buildup of this material has a deleterious effect on acid gas removal rates and accordingly, results in inefficient acid gas removal. In the process of the present invention, the cyclic urea degradation product is removed from the circulating solution by employing a selective precipitation of the cyclic urea followed by filtration. The selective precipitation is carried out by cooling the circulating solution to a particular temperature level such that the cyclic urea comes out of solution while the other components remain in solution.

摘要： A soluble HF/TaF.sub.5 catalyst is prepared in the absence of an organic solvent according to the steps of:(1) contacting tantalum metal with substantially anhydrous liquid HF to form soluble TaF.sub.5, the amount of HF being sufficient to maintain the TaF.sub.5 thus formed as a homogeneous substantially liquid phase catalyst at a temperature ranging from about 0.degree. to 150.degree. C.,(2) contacting the catalyst thus formed with a hydrocarbon feedstock in a hydrocarbon conversion process to form an acid catalyst phase and a hydrocarbon product phase,(3) stripping HF from said catalyst phase with a gas containing molecular hydrogen thereby reducing the mole ratio of HF to TaF.sub.5, and(4) passing the stripped acid catalyst phase from step (3) to the hydrocarbon conversion process, thereby maintaining the mole ratio of HF to TaF.sub.5 within said process at a level between that obtained in step (1) and step (3).

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.

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.
