ABSTRACT:
The invention is for a two phase gas and liquid mixture reacting in an improved fixed bed reactor having at least one auxiliary bed disposed above the main bed. The auxiliary beds each have separate liquid and gas bypasses comprising hollow tubing of relatively different lengths extending through the auxiliary bed. The gas bypass tubing projects to a greater height above the auxiliary bed than the liquid bypass tubing. This tubing bypass arrangement allows for a low pressure drop bypass of the auxiliary bed to the main bed by the liquid and gas when the auxiliary bed becomes fouled.
