CATALYTIC COMPOSITION (OPTIONS) AND A OLEFIN CONVERSION PROCESS INVOLVING IT Russian patent published in 2005 - IPC

FIELD: petrochemical process catalysts.

SUBSTANCE: invention is dealing with catalyst applicable in saturated hydrocarbon ammoxidation process resulting in corresponding unsaturated nitrile. Catalyst composition of invention comprises complex of catalytic oxides of iron, bismuth, molybdenum, cobalt, cerium, antimony, at least one of nickel and magnesium, and at least one of lithium, sodium, potassium, rubidium, and thallium and is described by following empirical formula: A_aB_bC_cFe_dBi_eCo_fCe_gSb_hMo_mO_x, wherein A represents at least one of Cr, P, Sn, Te, B, Ge, Zn, In, Mn, Ca, W, and mixtures thereof; B represents at least one of Li, Na, K, Rb, Cs, Ti, and mixtures thereof; C represents at least one of Ni, Mg, and mixtures thereof; a varies from 0 to 4.0, b from 0.01 to 1.5, c from 1.0 to 10.0, d from 0.1 to 5.0, e from 0.1 to 2.0, f from 0.1 to 10.0, g from 0.1 to 2.0, h from 0.1 to 2.0, m from 12.0 to 18.0, and m is a number determined by requirements of valences of other elements present. Ammoxidation processes for propylene, ethylene, or their mixtures to produce, respectively, acrylonitrile, methacrylonitrile, or their mixtures in presence of above-defined catalytic composition is likewise described.

EFFECT: increased olefin conversion.
