5. Production Technology

6. · Produce hydrogen from coal
Production Technology
· Produce hydrogen from coal
1.High temperature carbonization of coal (Coking of coal)
process:

7. · Produce hydrogen from coal
Production Technology
· Produce hydrogen from coal
1.Gasification of coal
High temperature(>900℃), ordinary or high pressure, coal will react with gasification agent(vapour or oxygen) and generate CO and H2. After turning CO to CO2 and purification, we can get hydrogen.

2.Carbon molecular sieve membrane CMSM（碳分子筛膜）
After carbonization, polymeric membrane will turn to porous membrane.
(Groups' decomposing forms nanopore.)

12. · PSA Pressure Swing Adsorption（变压吸附）
Production Technology
· PSA Pressure Swing Adsorption（变压吸附）
Adsorption capacity-pressure:
The adsorbent has different adsorption capacity to different adsorbate in the same partial pressure. And it has the character selectively adsorting specific component of mixed gas under a specific pressure.（选择吸收）
