Production of bio-fuel from alcohothermal liquefaction of rice straw over sulfated-graphene oxide
The objective of this research is to investigate the parameters for supercritical ethanol liquefaction of rice straw over sulfated graphene oxide. Graphene oxide was synthesized from thermal treatment of humic acid and then treated with different concentration of sulfuric acid using the wet impregna...
