Abstract

Pyrolysis of glycerol has been identified as a possible route for producing high added value fuels like renewable hydrogen (H 2 ). Crude glycerol (CG) is the main byproduct of biodiesel industry and without purification it is a low added value material due to the presence of impurities. Co-pyrolysis of CG with biomass may improve the efficiency of the process and as a primary step of gasification give important information concerning the maximization of H 2 concentration in the produced gas. Moreover, the thermochemical treatment of crude glycerol-biomass mixtures may offer several economic and environmental advantages in biodiesel industry and reduce the cost of biodiesel production. A mixture of CG with olive kernel (OK) was used as pyrolysis feed material. Pyrolysis of a 25 wt% mixture of CG with OK at high temperature (T = 720°C) seemed to promote steam reforming reactions leading to an increase of H 2 concentration of 11.6 vv% in the pyrolysis gas in comparison to H 2 in gas obtained by low temperature pyrolysis (T = 520°C). © 2012 Elsevier B.V.
