    Crab and cockle shells as heterogeneous catalysts in the production of biodiesel by Maniam, Gaanty Pragas, Boey, Peng-Lim, Abd Hamid, Shafida

    Published 2010
    “…Parametric studies have been investigated and optimal conditions were found to be catalyst amount, 5 wt.% and methanol/oil mass ratio, 0.5:1. The waste catalysts perform equally well as laboratory CaO, thus creating another low-cost catalyst source for producing biodiesel. …”
