摘要：Among various environmental concerns, a common one in agricultural countries is open air burning of crop residues to eliminate left-over after harvest. It causes serious health and environmental problems by causing higher NOx concentration and greenhouse gases emission. On the other hand, conversion of biomass owns promising potential for clean energy because it provides a carbon neutral resource of energy which is highly and diversely adaptable. Biomass energy can help energy-starved countries curb energy crisis without adding to their carbon emissions. In this study, Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) was applied to identify the product distribution of Pakistani agricultural residues (cotton stalk and bagasse) under 400-650°C pyrolysis temperature. The decomposition of cotton stalk and bagasse started at low temperature while the maximum desired pyrolytic products favorable to produce biooil and other valuable chemicals were achieved at 500°C. Based on the results, the effect of pyrolysis temperature on pyrolytic product distribution, generation of important products and the possible pyrolytic pathway were discussed to achieve valuable chemicals and bio-oil. The study showed encouraging results indicating utility of biomass to produce chemicals and bio-oil not only to curtail energy crisis and increase the share of renewables but also diminish the practice of open-air burning of this valuable waste to save the environment.
