Hydrogen Production via Aqueous Phase Reforming of Glycerol

Glycerol is a waste by-product obtained during the production of biodiesel. The mass production of biodiesel has causes the market price for this crude glycerol to crash. Since it is often costly to refine the glycerol for industrial use, study is done to solve the glycerol glut problem by convertin...
