High efficiency reformer for hydrogen production

The increased demand for hydrogen supply at refineries can be met by reforming unconventional sources like still gas. However, processing capabilities are limited based on traditional approaches due to the varying composition of still gas. We propose a simple system for hydrogen recovery from still gas to meet the growing demand of hydrogen in the refinery process without significant capital investment. Statement of how this Problem or Situation is Being Addressed: Use of novel catalyst and reactor technology will allow processing and reforming of still gas over a wide range of composition. Native sulfur from still gas will be effectively removed as H2S, followed by steam reforming for producing H2-rich syngas. H2 is recovered via adsorption to meet Department of Energy targets for hydrogen recovery and efficiency. During Phase I we will demonstrate the concept feasibility with prototype system development in Phase II. Commercial Applications and Other Benefits: Still gases are an attractive feedstock option for H2 generation. By utilizing low value, excess still/refinery gas, refineries can reduce their consumption of costly traditional petrochemical H2 plant feedstocks, such as natural gas, Liquefied Petroleum Gas, butane or naphtha, resulting in significant reduction in operation cost and energy savings.
