EFFECT OF C/N RATIO, AND OLR ON FERMENTATIVE H_2 PRODUCTION FROM LEATHER AND MUNICIPAL SOLID WASTES USING BATCH AND CSTR REACTORS

摘要

Hydrogen is potentially one of the major clean fuels of the future. Although it is produced through many technologies, fermentative H_2 production using solid wastes is an attractive renewable energy option for the Clean Developing Mechanism (CDM) and Renewable Obligation Certificates (ROC). The calorific value of H_2 is 142.35kJ.gm~(-1), whereas for CH4 it is only 44kJ.gm~(-1) and it has been estimated that around 0.1m~3.hr~(-1) of H_2 is required to produce 1kW capacity of Proton Exchange Membrane Fuel Cell (PEMFC) (Levin et al., 2004), and 0.4 to 0.5m~3.hr~(-1) of CH_4 is required to produce 1kW of power using a biogas CHP engine.
