Carbon dioxide emissions havebecome the subject of much government incentives and sparked major clean-up process initiatives throughout the motoring world. Although CO2 emissions are not solely from transportation, this sector contributes the most, with gasoline being the major sub-division.\u00a0 The development of electric and hydrogen cars have provided evidence that vehicles can be manufactured to achieve low emissions, while still providing the car with sufficient power. The combination of the Zero Emission Petrol Vehicle (ZEPV) concept, catalytic hydrogenation of CO2 and methanol to gasoline (MTG) process gasoline is not only zero emission but also sustainable through the use of carbon recycling, via renewable energy sources. However the low methanol yields, both selectivity and conversion, is the main problem in the methanol synthesis.\u00a0 The research showed that Molecular Sieve 4A could increase the CO2 conversion significantly.\u00a0 The objectives of this research are to develop a mathematical model for representing the effect of Molecular Sieve 4A on methanol synthesis and to analyse the feasibility study for re-syn fuel refinery from recycled CO2.<\/p>\n
