摘要: A fixed bed containing a particulate catalyst or sorbent material (10) subject to operation at high temperature having a shaped boundary member (16) inclined to the direction of fluid flow through the bed that maintains the depth of said catalyst or sorbent at the boundary of the bed through a series of thermal expansion-thermal contraction cycles is described. By maintaining bed depth, the shaped boundary member (16) can prevent bypass of, e.g. ammonia through a bed of particulate ammonia oxidation catalyst.

摘要: Ammonia synthesis gas production having a shift reaction stage employing a copper-based catalyst wherein the air supplied to the process is passed through an absorber that removes sulfur and/or halide contaminants, is described. The absorber has a support carrying an absorbent for sulfur compounds and/or absorbent for halide compounds. The removal of the contaminants improves the lifetime e.g. copper-zinc low temperature shift catalysts.
