Abstract

Decades of heavy reliance on petroleum refineries for energy have led to perpetual environmental pollution. These emissions include sulfur oxides, nitrogen oxides, carbon monoxide, and C1–C4 light hydrocarbons. Researchers worldwide strive to convert these pollutants into value-added products using catalysts. The current review provides a comprehensive overview of valorization of C4 hydrocarbons into value added chemicals, including methacrolein, methacrylic acid, or methyl methacrylate using a green solid catalyst, Keggin-type heteropolyacids. In this review, structures and properties related to catalytic activities are discussed, with the focus on the advancements of Keggin-type heteropolyacids. The influencing factors of the process design are then discussed and succeeded by mechanistic pathways. It is a timely review to place emphasis on sustainable and green chemistry resolution, meanwhile, advocating Sustainable Development Goals No. 8 Affordable and Clean Energy and No. 12 Responsible Consumption and Production.

通过凯金型杂多酸将 C4 碳氢化合物转化为高附加值化学品:结构特性、反应参数和机理
几十年来,人们严重依赖炼油厂提供能源,导致环境污染长期存在。这些排放物包括硫氧化物、氮氧化物、一氧化碳和 C1-C4 轻烃。全世界的研究人员都在努力利用催化剂将这些污染物转化为高附加值产品。本综述全面概述了利用绿色固体催化剂--凯金型杂多酸--将 C4 碳氢化合物转化为高附加值化学品(包括甲基丙烯醛、甲基丙烯酸或甲基丙烯酸甲酯)的过程。本综述讨论了与催化活性有关的结构和性质,重点是 Keggin 型杂多酸的进展。然后,讨论了工艺设计的影响因素,最后介绍了机制路径。本综述强调可持续和绿色化学决议,同时倡导可持续发展目标第 8 项 "负担得起的清洁能源 "和第 12 项 "负责任的消费和生产",可谓恰逢其时。
