Abstract
The main aim of this research work is to determine the potentials of biogas on groundnut shells and rice husk using heterogeneous catalysts. The result reveals yields produced in both groundnut shell and rice husk without catalyst were (650 cm3) and (608.9 cm3) respectively in comparison to the yield obtained through catalysts influence as (1418 cm3). However, proximate analysis of the substrate to indicates its viability for biogas generation is encouraging as the groundnut shell has moisture content (40.5 ± 0.06 %) while rice husk has (32.0 ± 0.02 %), volatile matter of groundnut shell and rice husk were (80.5 ± 0.45 %) and (71.5 ± 0.031 %) respectively. The result reveals that heterogeneous catalysts ZnO and CaO have little significant effects in biogas generation using both groundnut shell and husk shell as substrates. However, proximate analysis of the substrate indicated its viability for biogas generation is encouraging as the groundnut shell has the highest moisture content fallowed by rice husk. Elemental composition of the substrates proves that the slurry could be used as bio fertilizer as the nitrogen content was (1.16 ± 0.003) which is higher than that of rice husk (1.06 ± 0.05), phosphorus (4.14 ± 0.006) and potassium content for rice husk were higher than that of groundnut shell (16 ± 353), on comprising groundnut shell is more viable as a candidate for biogas generation.
