摘要： Normal olefins such as n-butene can be converted to branched species by skeletal isomerization over catalysts containing solid acids prepared by sulfating catalyst precursors containing hydrous metal oxides--e.g., aluminas, silica-aluminas or clays treated with sulfuric acid, metal sulfates, sulfur trioxide or organic sulfates. The catalyst precursors are sulfated sufficiently to produce the desired skeletal isomerization without substantial cracking under suitable isomerization conditions.

摘要： The selective conversion by skeletal isomerization over steam pretreated ferrierite zeolite-based catalysts having pore sizes of at least about 4.2 Angstroms and a pore structure characterized by intersecting 10-MR and 8-MR channels. The steam pretreated ferrierite zeolite-based catalysts have sufficient acidity to catalyze the skeletal isomerization of normal olefins. The catalysts can be used to produce isoolefins for reaction with alcohols in integrated processes to produce tertiary amyl methyl ethers such as TAME.

摘要： Method and apparatus for forming a coating material, and for depositing the material onto the surface of an article or a substrate. The apparatus includes a tank within which the coating composition is formed together with a residual amount of gas. The tank and the internal support members are electrically segregated from a perforated container with reactant material held on the internal support to avoid the formation of gas bubbles on the surfaces of the tank and support which are immersed into the coating composition.
