摘要：
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.
