Methanol is one of the clean burning fuel with versatile applications. As a combustion fuel, it provides extremely low emissions. Methanol can also be used as a primary transporation fuel or a fuel additive and expecially as a raw metalial for methyl t-butyl ether. Methanol synthesis from synthetic gas was carried out in the Ru-CuO/ZnO/Al2O3 catalytic system. The influence of various factors, such as the reaction temperature, the concentration of ruthenium (Ru) and the reaction pressure was discussed, respectively, and the most preferred condition were obtained. The results showed that metanol synthesis could be prepared from carbon monoxide and hydrogen under reaction conditions. The reaction of Ru-CuO/ZnO/Al2O3 catalyst (E-catalyst) was operated most preferably at 160oC and 40 bar.

Numerical study is conducted to predict effects of radiative heat loss and fuel composition in synthetic gas diffusion flame diluted with CO₂. The existing reaction models in synthetic gas flames diluted with CO₂ are evaluated. Numerical simulations with and without gas radiation, based on an optical thin model, are also performed to concrete impacts on effects of radiative heat loss in flame characteristics. Importantly contributing reaction steps to heat release rate are compared for synthetic gas flames with and without CO₂ dilution. It is also addressed that the composition of synthetic gas mixtures and their radiative heat losses through the addition of CO₂ modify the reaction pathways of oxidation diluted with CO₂.
