Production Technology

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

· 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.

· Produce hydrogen from coal Production Technology · Produce hydrogen from coal key: Gasification technology of coal √ reaction rate · Design of reacting furnace · Gasification process · Heat source · Gasification methed

· Produce hydrogen from coal Production Technology · Produce hydrogen from coal key: Gas(H2 and CO2) separation √ energy conservation and Eco-Friendly · Membrane separation · PSA Pressure Swing Adsorption（变压吸附）

· Gas separation membrane Production Technology · Gas separation membrane porous inorganic membrane（无机多孔膜） 1.Zeolite membrane（分子筛膜） Alumino-silicate(SiO4 and AlO4 tetrahedron) Chemical constitution

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

· 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）

· From nature gas and vapour Production Technology · From nature gas and vapour Catalyst : Ni Q: separation and purification of hydrogen?

· From methyl alcohol（甲醇催化重整） Production Technology · From methyl alcohol（甲醇催化重整） reaction mechanism：

· Industrial waste gas 1.Chlor-alkali chlorine alkali industry（氯碱工业）： Production Technology · Industrial waste gas 1.Chlor-alkali chlorine alkali industry（氯碱工业）： In 2003, there are more than 200 Chlor-alkali plant in China. Production of NaOH is more than 11,000,000 tons H2 240,000 2.Synthetic ammonia industry（合成氨工业）

· Electrolysis of water Production Technology · Electrolysis of water High purity but low energy efficiency · Biological production of hydrogen（生物制氢） Trough fermentation, turn biology polysaccharide to hydrogen.

Storage

· Physical hydrogenous storage 1.High pressure vessel ~700atm（标准大气压） 2.Lower temperature liquefaction boiling point: 20.3K ~high energy consumption 3.Physical absorption material with high specific surface area（高比表面积材料）:Activated carbon, CNT Carbon Nano Tube and so on.

· Chemical hydrogenous storage 1. Metal: pure metal: Pd, Mg, Ti, rare earth 2. Organics: some arene
