阐述用硫化氢生产氢、乙烯、丙烯等新技术的基本原理,由于其中涉及元素硫的生产,故可将其作为硫回收总体方案中的一部分。这些工艺的主要优点是,生产每种终端产品时不必输入外部能量,因此燃料消耗大大低于目前采用的氢和烯烃生产工艺。此外,乙烯和丙烯的产率较高,选择性较好。这些技术的另一个重要方面是,在所谓的石油时代以后,由于可用生物质作为有机原料,并用硫磺作为循环方案的最初氧化剂,故它们是可持续的。 Describe the basic principle of hydrogen sulfide, ethylene, propylene and other new technologies for hydrogen sulfide production. Since it involves the production of elemental sulfur, it can be used as a part of the overall sulfur recovery program. The main advantage of these processes is that there is no need to input external energy for the production of each end product and therefore the fuel consumption is substantially lower than the currently used hydrogen and olefin production processes. In addition, the yield of ethylene and propylene is higher and the selectivity is better. Another important aspect of these technologies is that they are sustainable after the so-called petroleum era, thanks to the biomass available as organic feedstock and the use of sulfur as the initial oxidant in recycle programs.
