Used date pits biomass as a green carbon catalysts is of increasing interest as inexpensive feedstock for biodiesel production. In this work, an efficient utilization of waste date pits biomass for synthesizing green carbon catalyst as well as production of biodiesel were investigated. This method is used an applicable technology for recovery of energy and resources during waste treatment. The green carbon catalyst was modified by KOH and characterized by scanning electron microscopy (SEM). study the effect of several process parameters such as reaction temperature, time, catalysts type and methanol to oil ratio, on the yield of the produced biodiesel. The optimized yield obtained was 93.2% when the process temperature was 65oC, with 5wt.% of catalyst (6wt% KOH on carbon) within 90min and with 1:7 methanol to oil ratio. Waste date pits biomass can be a promising platform for the production of green carbon catalysts as well as biodiesel production.
