Biogas To Hydrogen Upgrade, Biogas Upgrading, Environmental Low
Cost
The concept of upgrading biogas to hydrogen has been studied for
many years. Biogas is produced by microorganisms in aerobic
digesters and consists mainly of methane and carbon dioxide (CO2).
It is a renewable, clean and economical fuel after desulfurization
treatment.
Methane purification technology of biogas
Biogas is an environmentally friendly, clean, and inexpensive
combustible gas produced by microorganisms in anaerobic
environments, such as livestock manure, agricultural waste,
industrial organic waste, domestic sewage, and municipal solid
waste. The main components are methane, carbon dioxide, and
hydrogen sulfide. Biogas is mainly used for urban gas, automotive
fuel, and hydrogen production.
Ally Hi-Tech has commercialized lots of facilities to process the
biogas into bio-CNG as the supplementary fuel for the logistic
trucks in Guangdong and Shandong.
Technology Characteristics
Mature technology, safe and reliable;
Flexible processing scale, high methane recovery rate, and high
purity;
The process is simple, easy to operate, and has a high degree of
automation control;
Less land occupation, less investment, and short investment payback
period;
Low energy consumption and low product cost.
Technical Process
Biogas is compressed by desulfurization and then purified by
pressure swing adsorption (PSA).
