Production of biolubricant from Jatropha curcas seed oil

Extracted Jatropha oil was analyzed for their chemical and physical properties such as density, acid value, % FFA, saponification value as well as viscosities at 40 and 100oC and viscosity index. The result of the analyses of the Jatropha oil reveals that it has a very high %FFA (14.6%). Reduction was achieved by esterification with methanol (to 0.44%). The method employed for the production of biolubricant...

BOD5 removal from tannery wastewater over ZnO-ZnFe2O4 composite photocatalyst supported on activated carbon

Tannery wastewater with high biological oxygen demand (BOD5) was treated with ZnO-ZnFe2O4composite photocatalyst supported on activated carbon under visible light irradiation. Only 9% of BOD5 in the raw effluent were removed via adsorption on the surface of the photocatalyst in the dark for two hours. Photocatalysis with ZnO-ZnFe2O4 composite photocatalyst on activated carbon support removed 90% of...
