| Summary: | Bio-oil nowadays is seriously considered to be one of the favorable, renewable and alternative energy sources to replace fossil fuel and has become a significant energy carrier for transportation, industrial and commercial applications. However, bio-oil comprises of complex mixture of organic compounds with low calorific value and high oxygen content. Hence this work investigates the conversion of major compounds present in bio-oil i.e. aldehyde, ketone, phenol, acetic acid and water, in presence of HZSM-5 at temperatures of 300, 400 and 500ºC, at atmospheric pressure under nitrogen flow. It was observed that the conversion of phenol, aldehyde, and acetic acid were increased when the temperature was increased. The maximum conversion of all the compounds was observed to occur at 500ºC. The degree of deoxygenation of the bio-oil was increased by 27.68 % via catalytic cracking. With the increase in temperature for cracking, the yield of organic liquid product (OLP) decreased, and its H/C ratio of increased with O/C ratio decreased. The OLP was found to have high calorific value and low oxygen content, compared to the bio-oil. The study proved the potential of conversion of model compounds in bio-oil into high-value OLP using HZSM-5.
