Thermodynamic and Experimental Study on Alcohol Made by Synthesis Gas

First C₁-C₅ alcohols which were very important in practical application were analyzed, and the thermodynamic analysis for the synthesis of C₁-C₅ alcohols can guide the experiment in praxis. In the article the equilibrium constants were used to analyze the thermodynamic of the synthesis of C₁-C₅ alcohols and verified the calculation results in line with the trends of theoretical analysis. Reducing temperature and raising the pressure is useful for CO conversion rate and the generation of C1-C5 alcohols, as well as different molar ratio of H₂/CO influence CO conversion rate. Eventually the optimum condition was confirmed. A new type of catalyst was developed, which can increase the yield of alcohols, then the theoretical analysis's correctness are verified by the experimental data.

I. Introduction

With the decrease of oil resource and enhancement of environmental consciousness, the synthesis of alcohols from coal, natural gas and organic waste has become one of the important research contents of chemical. The main application of liquid fuel represented by alcohols is used as pure gasoline additives alcohols, as we define it here, is mainly based on ethanol and partly based on alcohol) and a kind of clean fuel alone[1].
