    摘要: The invention relates to a process for converting oxygenated organic material, to olefins using small pore molecular sieve catalysts. More particularly, the invention relates to a method for converting oxygenated organic material to olefins with improved the olefin yields and decreased yields of methane and other light saturate byproducts. The improved yield slate is achieved by treating the small pore molecular sieve catalyst with a modifier selected from the group consisting of polynuclear aromatic heterocyclic compounds with at least three interconnected ring structures having at least one nitrogen atom as a ring substituent, each ring structure having at least five ring members, decomposed derivatives of said polynuclear aromatic heterocyclic compound, and mixtures thereof.

    摘要: A process for the modification of a small pore molecular sieve catalyst to increase its selectivity to ethylene in the production of light olefins from oxygenated compounds, particularly methanol. The catalyst is modified with phosphorus by incorporating a phosphonitrilic oligomer with the catalyst, and then calcining the catalyst at temperature sufficient to decompose the phosphonitrilic oligomer, and deposit from about 0.001 wt. % to about 50 wt. % phosphorus on the catalyst. This modification provides a novel composition in that it increases the ethylene selectivity of the catalyst in the production of light olefins from oxygenates as contrasted with a small pore molecular sieve catalyst otherwise similar except that it has not been so treated and modified with the phosphonitrilic oligomer.
