Mesoporous acidic catalysts synthesis from dual-stage and rising co-current gasification char: application for FAME production from waste cooking oil

The main purpose of this work is to investigate the application options of the char produced from gasification plants. Two promising mesoporous acidic catalysts were synthesized using char as a support material. Two char samples were collected from either a dual-stage or a rising co-current biomass...
