Pyrolysis of agricultural waste: effect of temperature and heating rate

Due to the depleting of non-renewable source energy (fossil fuel) and increases of environmental pollution, a search of sustainable alternative has gained significant attention. This involves the conversion of biomass from palm waste which are empty fruit bunch (EFB) and palm oil fiber (POF) to prod...
