Abstract:
1. A process for removing tars from synthesis gas, comprising the steps of treating synthesis gas containing a first amount of tars that impede utilization with glycerol to produce a first stream of synthesis gas containing a second amount of tars less than the first amount and a second stream containing a rich glycerol and tars solution wherein the glycerol used in said treatment step is obtained by combining the crude glycerol from a biodiesel process and the rich glycerol and tars solution from said treatment step to make a combined solution; and conditioning the combined solution to obtain conditioned glycerol wherein said conditioning step includes stripping the glycerol and tars from the combined solution to produce a first stream containing steam and tars and a second stream containing conditioned glycerol.
