Hydrogen From Biogas Upgrading, High Purity Hydrogen Production

Biogas is produced in the aerobic fermentation digestor by microorganisms, which is mostly composed of methane and carbon dioxide (CO2). It is a kind of renewable and clean and economical fuel after a sweetening process.

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.

Process Schematic

Process Description

Biogas is compressed and desulfurized, and then it is decarbonized and purified via PSA, afterward, it passes through deoxidation and TSA non-destructive drying as to get the product gas which meets the requirement of automobile fuel gas.
