The glycerol (stream 1) ismixed with water (stream 3) and is vaporized and heated. The mixture is passed through areactor and the resulting product, ethane and CO 2 (stream 8), is sent to the biogas process gasupgrading for CO 2 removal. The process is simpler than the ones suggested above, but a largeramount (40% excess) is needed to get the correct Wobbe-index of the biogas.16
