A process for producing liquid and, optionally, gaseous products from gaseous reactants feeds (18), at a low level, gaseous reactants into a slurry bed of solid catalyst particles (14) suspended in a suspension liquid. The gaseous reactants are allowed to react as they pass upwardly through the slurry bed (14), hereby to form liquid and, optionally, gaseous products. The reaction is catalyzed by the catalyst particles. Liquid product is separated from the catalyst particles by passing, in a filtration zone (22) within the slurry bed, liquid product through a filtering medium having a plurality of openings through which the liquid passes. The openings have a controlling dimension of x microns. The proportion of catalyst particles, which have a particle size smaller than x microns, in the slurry bed is less than 18% by volume based on the total volume of the catalyst in the slurry bed.
