HYDROGEN SEPARATION FROM SYNTHESIS GAS NEAR STP

摘要

A hydrogen separation system and membrane is described for extracting hydrogen from gasifier streams at near atmospheric pressure and ambient temperature conditions. The system can be inserted between a small gasifier and an internal combustion engine which runs a genset to optionally co-produce hydrogen and electricity.

1. A system for extracting hydrogen from a gas stream between a downdraft gasifier and an associated engine genset, the system comprising:
a bypass valve disposed between the gasifier and the engine genset for routing the gas stream through a hydrogen concentrator; and the hydrogen concentrator for concentrating the gas stream, the hydrogen concentrator comprising a filter for filtering the gas stream, a pump for pumping the gas stream through the hydrogen concentrator, a membrane, and a hydrogen compressor; wherein the membrane comprises a permselective membrane for permeating hydrogen from the gas stream.
