With stricter ecological regulation and reduction of fossil feedstock, the research works have been oriented to renewable resources. Various bio-based molecules have been proposed for replacing the platform chemicals based on crude oil, but there are not yet well-established processes for producing these chemicals at large scale. As a result, in the short to midterm, a main impact will be expected from the production of bio-based bulk chemicals having identical structures as today’s bulk chemicals, including ethylene, which is a key intermediate for the production of platform molecules. The commercial method for producing ethylene is based on steam thermal cracking, but emerging methods using alternative sources (natural gas, coal, biomass) are very promising processes. For example, the high-volume production of ethylene by ethanol dehydration has become an economically feasible application. This perspective summarizes the advances in catalysts, processes, and fundamental understanding of reaction mechanisms in ethylene conversion to other high-value hydrocarbons, including propylene, butenes, and BTX aromatics.

从基于生物的乙烯向平台化学品发展：多相催化剂和工艺

随着更严格的生态法规和化石原料的减少，研究工作已转向可再生资源。已经提出了各种生物基分子来代替基于原油的平台化学品，但是还没有成熟的大规模生产这些化学品的方法。结果，在短期到中期，预计将产生具有与当今的大宗化学品相同结构的生物基大宗化学品的主要影响，包括乙烯，后者是生产平台分子的关键中间体。生产乙烯的商业方法基于蒸汽热裂化，但是使用替代来源（天然气，煤炭，生物质）的新兴方法是非常有前途的方法。例如，通过乙醇脱水大量生产乙烯已成为经济上可行的应用。该观点概述了在乙烯转化为其他高价值烃（包括丙烯，丁烯和BTX芳烃）中催化剂，工艺和对反应机理的基本理解方面的进展。
