A slurry hydrocarbon synthesis process with reduced catalyst attrition is achieved by injecting a synthesis gas comprising a mixture of H.sub.2 and CO up into the reactive slurry with a gas distribution grid having gas injectors horizontally arrayed across, and vertically extending through, an otherwise gas and liquid impervious plate. The injectors have a throat with a gas pressure reducing orifice at one end, which is the bottom and gas entrance end, and the other end opening into an open cone in which the uprising gas contacts the slurry. Flow diverting means in the injectors prevents slurry from entering the throat and being attrited. The gas injectors do not protrude above the top surface of the plate and flat space is eliminated by means such as angular fillers, to prevent solids accumulation top of the tray.

[ What is claimed is:] [1.] A hydrocarbon synthesis process which comprises:(a) injecting a synthesis gas comprising a mixture of H.sub.2 and CO up into a slurry which comprises a solid, particulate hydrocarbon synthesis catalyst and gas bubbles in a hydrocarbon slurry liquid, wherein said synthesis gas is injected up into the bottom of said slurry by means of a gas distribution grid located at the bottom thereof which comprises a plurality of gas injectors horizontally arrayed across, and extending vertically through, an otherwise gas and liquid impervious plate, said injectors each comprising an elongated, hollow, first gas expansion zone open at both ends and having a pressure reducing bore at one end, which is the entrance end and with the other end opening into the bottom end of an upward and outward extending, hollow second gas expansion zone open at both ends, with a flow diverting means located proximate the junction of said first and second zones for imparting a radially inward flow direction to liquid flowing from said second towards said first zone, and(b) reacting said H.sub.2 and CO in the presence of said catalyst in said slurry at reaction conditions elective to form hydrocarbons, at least a portion of which are liquid at said reaction conditions and wherein said slurry hydrocarbon liquid comprises said synthesized liquid hydrocarbons.
