Membrane for Hydrogen Recovery from Streams Containing Hydrogen Sulfide


Description of Technology:

This technology is a membrane for hydrogen recovery from streams containing hydrogen sulfide. The membrane comprises a substrate, a hydrogen permeable first membrane layer deposited on the substrate, and a second membrane layer deposited on the first layer. The second layer contains sulfides to transition metals and positioned on a feed side of the hydrogen sulfide stream. This technology also includes a method for the direct decomposition of hydrogen sulfide to hydrogen and sulfur.


This technology is meant to be a viable alternative to the Claus process for H2S treatment where complete H2S conversion can be obtained without the need for expensive tail gas clean up steps.

Features and Benefits:

The Membranes for Hydrogen Recovery have the following advantages: they are simple to synthesize using chemical vapor deposition, electrolytic plating and other chemical synthesis routes; they are effective for permeation and removal of hydrogen from reaction zones wherein H2S from process streams undergoes decomposition; and they are effective for permeation and removal of hydrogen from reaction zones, involving synthesis or treatment of hydrocarbon and other process streams, wherein the fluid stream contains H2S.
