Abstract
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. The hydrogen is used in a number of important industrial processes.

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;
- and
- wherein the extracted hydrogen is reacted with non-renewable chemicals or combined with carbon, oxygen, or nitrogen in the presence of heat to produce renewable chemicals.
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 formed from a bulk carbon which is compressed and held in form by sintered PTFE, and a hydrogen compressor;
- wherein the membrane comprises a permselective membrane for permeating hydrogen from the gas stream;
- and
- wherein the extracted hydrogen is stored, compressed and used in a fuel cell vehicle.
