    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 process for cogelling a smectite with an inorganic metal oxide which is unstable with respect to retaining a high surface area, to produce a cogel of high surface area which has good retention of surface area at high temperatures. Suitable smectites for the practice of this invention are hectorite, chlorite, montmorillionite, beidellite, or admixtures of two or more of these materials with each other or with other materials, or the like. Exemplary of inorganic oxide gels suitable for the practice of this invention are the Group IV-B metal oxides, especially titanium oxide, and other metal oxides such as the oxides of thorium, uranium, silicon, aluminum, and the like.

    摘要: A novel catalyst precursor which comprises a Group IV-B transition metal oxide deposited on the surface of an inorganic metal oxide support, preferably alumina; especially where the Group IV-B transition metal oxide is deposited on the support surface as discrete areas separated by areas of support surface which contain little, if any, of said Group IV-B transition metal oxide; and a catalyst composition comprised of a cluster of a Group IV-B transition metal oxide and a Group VIII metal preferably a Group VIII noble metal, deposited on an inorganic metal oxide support, particularly an alumina support, especially where the clusters are deposited on the surface of the support, as discrete clusters separated by areas of support surface which contain little, if any, of said Group VI-B transition metal oxide, or clusters of said Group IV-B and Group VIII metals. The catalyst precursor is prepared by forming a nonaqueous solution of a compound, or compounds, of the Group IV-B metal, contacting and impregnating the desired support with said solution, to deposit said compound, or compounds, of the Group IV-B metal, drying and then calcining said support in a moist atmosphere to form said Group IV-B transition metal oxide upon the support surface, preferably as discrete areas upon the support surface between which there are areas of support surface which contain little, if any, of the transition metal oxide. Such supports can then be impregnated with a solution of a Group VIII noble metal, dried and then calcined to form clusters of said Group IV-B transition metal oxides and said Group VIII noble metals, particularly clusters of such type which are separated by areas devoid of such clusters.
