摘要： Organic hydrocarbons which comprise useful compounds may be obtained in a two-step process utilizing methane as a feedstock. The desired compounds are prepared by treating said methane with a halogenating agent such as chlorine, followed by contacting the methyl halide with a conversion catalyst comprising a silicalite. The silicalite which is employed is a silica polymorph consisting of crystalline silica which, after calcination in air at a temperature of 600.degree. C. for 1 hour, has a mean refractory index of 1.39.+-.0.01 and a specific gravity at 25.degree. C. of 1.70.+-.0.05 g/cc.

摘要： An alkylation-transalkylation process for the production of a monoalkylated aromatic compound is disclosed which maximizes the production of desirable monoalkylaromatic compounds, while limiting transalkylation catalyst deactivation. The process entails the combination of an alkylation reaction zone, a first seperation zone, a second separation zone, and a transalkylation reaction zone wherein the alkylation catalyst and transalkylation catalyst are dissimilar and where the alkylation catalyst is comprised of phosphoric acid material and the transalkylation catalyst is comprised of a crystalline aluminosilicate material. The transalkylation catalyst deactivation is reduced by transalkylating only dialkylated aromatic compounds. Additionally, the transalkylation catalyst is regenerable utilizing a hot liquid hydrocarbon wash.

摘要： Catalyst particles which are employed in reactions involving the conversion of organic compounds should possess a desired configuration in order to maintain a desired voidage which will permit passage of the feedstock through the catalyst bed during the conversion reaction. Solid phosphoric acid catalysts which comprise an admixture of an acid of phosphorus and a solid binder such as a siliceous material may be formed into polylobular, tubular, ridged, fluted, or channeled cylindrical particles which will permit a sufficient amount of voidage in the catalyst bed to be maintained even though the catalyst particles will swell during the reaction due to the formation of coke on the surface thereof.

摘要： A catalyst for converting methanol to light olefins and the process for making and using the catalyst are disclosed and claimed. SAPO-34 is a specific catalyst that benefits from its preparation in accordance with this invention. A seed material is used in making the catalyst that has a higher content of the EL metal than is found in the principal part of the catalyst. The molecular sieve has predominantly a roughly rectangular parallelepiped morphology crystal structure with a lower fault density and a better selectivity for light olefins.
