Biochar layer boosts hydrogen rich gas yields from corn straw

Tokyo, Japan (SPX) Dec 26, 2025
Biochar can help convert agricultural residues such as corn straw into hydrogen rich gas while limiting carbon deposits on metal catalysts, according to a study in the journal Biochar. Researchers developed a two stage catalytic process in which corn straw vapors first pass through a biochar layer and then over nickel based catalysts, more than doubling hydrogen content in the product gas and sh
