Abstract
A continuous catalytic process for converting ethene-rich olefinic feedstock containing reducing gas to heavier liquid hydrocarbon product, comprising the steps of PA0 contacting the ethene-rich feedstock at elevated temperature in a catalytic reaction zone with a zeolite catalyst comprising a nickel-ethene oligomerization component and a shape-selective medium pore acid zeolite oligomerization component to convert at least a portion of the lower olefinic components to heavier olefinic hydrocarbons; and PA0 feeding water with the feedstock in sufficient amount to prevent substantial reduction of the nickel component.
