Hydrogen production from glycerol using copper and nickel loaded zeolite based catalyst

The increasing of the growth rate for vehicles leads to the high production of biodiesel and gives a large amount of glycerol as the by-product via transesterification reaction. Moreover, the limited of the world demand for glycerol makes the glycerol as a waste and abundant substance. For that reas...
