A steam-hydrocarbon reforming process utilizing a prereformer where a portion of the effluent from the prereformer is conditioned and the C2+ hydrocarbon content in the conditioned effluent measured. The molar flow rate of steam to the prereformer is increased or decreased responsive to measuring the C2+ hydrocarbon content of the conditioned effluent.

Steam-hydrocarbon reforming process

A method to reduce the cycle time in a pressure swing adsorption process by reducing the required pressure equalization time in a cycle, thereby reducing the overall cycle time and increasing product recovery per unit of adsorbent used. This reduces the amount of adsorbent required in the beds for a given feed rate while continuing to provide product at an acceptable product purity, and has the desirable effect of reducing the capital cost of the process equipment required for a given volumetric production rate.
