Abstract
Abstract Synthesis of ethanol by CO2 hydrogenation presents an efficient way to convert CO2 into value-added fuels and chemicals. For practical applications, recycling unreacted tail gas as well as CO co-feeding plays a key role to enhance CO2 conversion to ethanol. Thus, it is of great significance to study the effects of recycling unreacted tail gas and CO co-feeding on the chemical equilibrium. Herein, we perform a thermodynamic study to analyze the hydrogenation of CO2 to ethanol using Aspen Plus. The effects of recycling tail gas and CO co-feeding on CO2 conversion and ethanol selectivity at different temperatures and pressures are investigated. Both the optimal recycle ratio and CO/(CO + CO2) ratio in the feed are found to enhance ethanol synthesis from CO2 hydrogenation.
期刊介绍：
Chemical Engineering Communications provides a forum for the publication of manuscripts reporting on results of both basic and applied research in all areas of chemical engineering. The journal''s audience includes researchers and practitioners in academia, industry, and government.
Chemical Engineering Communications publishes full-length research articles dealing with completed research projects on subjects such as experimentation (both techniques and data) and new theoretical models. Critical review papers reporting on the current state of the art in topical areas of chemical engineering are also welcome; submission of these is strongly encouraged.
