Increasing energy demand, world has generated significant interest in using renewable, sustainable and environmental friendly fuels simultaneously diminishing fossil fuels concerns that are known to deplete in future and lead to environmental issues. Renewable energy is taking path for sure to replace fossil fuels. Bio oil is considered to be potential candidate which obtain from various renewable resources. Bio oils are very complex mixtures of short and long chain oxygenated compounds. In order to make use of the available bio-oil, the relatively longer carbon chain of bio-oil will be cracked to smaller carbon compounds. Equilibrium thermodynamic analysis of light olefins production from bio-oil model compound has been recently conducted using total Gibbs free energy minimization technique. The co-cracking of ethyl acetate as bio-oil model compound has not been studied for the light hydrocarbon production. The following parameter range was used to compute the thermodynamic equilibrium compositions for co-cracking of ethyl acetate: temperature (300 - 1,200 °C); ethyl acetate/methanol ratio (EAMR) and ethyl acetate/ethanol ratio (EAER) of 1:12, 1:6, 1:3, 1:1, 2:1 and pressure (1 bar). Hydrogen, carbon monoxide, carbon dioxide and coke are among the products that are formed alongside the light hydrocarbon through literature review. According to equilibrium studies, ethylene production is low in proportion to syngas such as hydrogen and carbon monoxide. Nevertheless, optimum conditions for the production of ethylene are EAMR ratio 2:1, at 1,200 °C and 1 bar, and EAER ratio 2:1, at 1,200 °C and 1 bar.
