Abstract: Attrition resistant bismuth-containing metal/oxygen compositions comprising the infusion and reaction product of an alumina existing in a crystal form selected from the group consisting of .gamma., .delta., .eta., and .chi. crystal forms, and mixtures thereof or that can be transformed by heat to such crystal forms, and characterized by a mean particle size from about 10 .mu.m to about 200 .mu.m, a fractional porosity of at least 0.2, a surface area of at least 150 m.sup.2 /g, and a pore diameter such that at least 10 percent of the pores are less than 55 .ANG., and at least one bismuth oxide, or compound convertible by heat to such bismuth oxide, having a maximum mean particle size of about 100 .mu.m, with the proviso that the alumina/bismuth oxide mean particle size ratio is at least 2, which bismuth oxide is susceptible of undergoing infusion and reaction with the alumina upon being subjected to temperatures of at least 0.4 T.sub.

Abstract: Attrition resistant bismuth-containing metal/oxygen compositions comprising the infusion and reaction product of alumina and at least one bismuth oxide, or compound convertible by heat to such bismuth oxide, which bismuth oxide is susceptible of undergoing infusion and reaction with the alumina, are useful in metal oxide-catalyzed reactions. The compositions are especially useful in reactions which involve reaction conditions of high stress, for example, vapor phase oxidations under fluidized bed conditions.

Abstract: This invention relates to the treatment of carbon-containing materials. In one aspect this invention relates to the treatment of carbon-containing materials, such as coal, coke and hydrocarbons to produce oxides of carbon therefrom. In still another aspect, this invention relates to a process for the production of high purity synthesis gas, a mixture of hydrogen and carbon monoxide, from carbon-containing materials. More specifically, this invention relates to inorganic metal-oxygen containing materials useful as the oxidant, oxygen carrier and supplier, and heat transfer agent for the endothermic oxidative gasification of carbon-containing materials.

Abstract: Carbon-containing materials are gasified to produce synthesis gas, a mixture of hydrogen and carbon monoxide, in a three zone unified system (oxidizer, reducer and gasifier) using a metal oxide as the oxygen and heat source for the gasification with steam and carbon dioxide. Synthesis gas contacts the metal oxide prior to the gasification to release the oxygen and convert the synthesis gas to steam and carbon dioxide as the gasification medium.
