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).
