Production of hydrogen rich bio-oil derived syngas from co-gasification of bio-oil and waste engine oil as feedstock for lower alcohols synthesis in two-stage bed reactor

Hydrogen rich bio-oil-derived syngas with desirable composition (H2/CO > 2.0) was effectively produced by Non-catalytic partial oxidation (NPOX) technology using bio-oil and waste engine oil as gasification feedstock, then lower alcohols was effectively synthesized over the CZA(2.5)//CFCK(2.5) two-stage bed catalyst combination system from the hydrogen rich bio-oil-derived syngas.176
