摘要

研究表明，乙醇蒸汽转化（SRE）或乙醇转化为丙烯（ETP）过程的初始反应途径可能相同，包括脱氢和缩合反应，并形成乙醛和丙酮。与 SRE 不同，ETP 工艺中丙烯和氢气的平衡产率与温度和乙醇浓度的关系不大。根据含碳化合物的选择性，提出了一个确定氢产率的方程式，根据该方程式可以计算出 SRE 和 ETP 工艺产物中的氢浓度。

Thermodynamic and Kinetic Analysis of Catalytic Processes of Bioethanol Conversion for Hydrogen and Propylene Obtaining

It is shown that the initial reaction pathways of the processes of steam reforming of ethanol (SRE) or ethanol to propylene (ETP) conversion can be the same and include dehydrogenation and condensation reactions with the formation of acetaldehyde and acetone. The equilibrium yields of propylene and hydrogen in the ETP process, in contrast to SRE, depend little on both temperature and ethanol concentration. An equation for the determination of hydrogen yield as the function of selectivity of carbon-containing compounds has been proposed, based on which the hydrogen concentration in products of the SRE and ETP processes can be calculated.
