    Abstract: Catalysts comprising a silica molecular sieve modified by a metal which forms acidic oxides selected from the group consisting of Group VIB and VIIB elements and, a Fischer-Tropsch catalyst wherein the ratio of zeolite to Fischer-Tropsch component is from 0.1 to 10:1 can be employed to produce gasoline quality liquid hydrocarbons from synthesis gas. A process is employed which includes the step of contacting synthesis gas having a ratio of hydrogen to carbon oxides of from 0.1 to 10.0:1 over the foregoing catalyst at a reaction temperature of from 100 . C to 500°C and at a pressure of from one atmosphere (0.1 MPa) to 200 atmospheres (20 MPa) and at a gas hourly space velocity of from 10 to 100,000. A method is also provided for the preparation of the combination catalyst. The liquid hydrocarbon product is highly aromatic, essentially free of external olefins and totally free of detectable oxygenates.

    Abstract: A process of producing a fluid bed oxacylation catalyst for olefins and diolefins having the following formula Pd-M-A where

    M = Ba, Au, Cd, Bi, Cu, Mn, Fe, Co, Ce, U or mixtures thereof,
    A = an alkali metal or mixture thereof, and
    M is present in the range of from 0 to 5 wt%,
    A is present in the range of greater than 0 to 10 wt%,
    comprising milling a fixed bed oxacylation catalyst precursor comprising Pd-M on a fixed support with a fluid bed catalyst binder material to form a uniform slurry, drying the slurry to form microspheroidal particles of solid fluid bed catalyst precursor and optionally impregnating the microspheroidal particles with a solution of alkali metal salt to form the fluid bed catalyst. The catalyst is particularly useful in the manufacture of vinyl acetate from ethylene, acetic acid and oxygen.
