SBIR Phase II: Hydrogen Production via Ultra-Rich Superadiabatic Combustion of Hydrogen Sulfide in a Reverse Flow Reactor

本小型企业创新研究（SBIR）二期项目拟开发一种利用超绝热逆流反应器将硫化氢转化为氢并同时回收硫的新工艺。目前，每年产生的七百万吨硫化氢是硫化物与氢反应的副产品，这些硫化氢被克劳斯反应器加工成硫，而更有价值的氢则被氧化浪费掉了。该工艺的成功开发将为通过保留氢来处理硫化氢提供一种经济的方法。一期项目在没有外部能源帮助的情况下获得了有史以来最高的硫化氢产氢量。此外，该项目证明，反应堆在消除二氧化硫的制度下运行。在第一阶段积极成果的基础上；在第二阶段，将建造和测试一个小型试验工厂，为设计最小修改的商业反应堆奠定基础。汽油和天然气的高价格部分是由于在原油精炼过程中提取含硫化合物的成本很高。这种脱硫过程使用氢（主要从天然气中获得）与有机硫反应形成硫化氢。一种可以从硫化氢中生产氢和硫的工艺除了可以降低消费者的汽油、柴油和天然气的成本外，还可以每年为能源行业节省数亿美元。此外，该过程还将消除处理硫化氢过程中产生的数百万吨导致酸雨的二氧化硫。

This Small Business Innovation Research (SBIR) Phase II project proposes to develop a new process employing the superadiabatic reverse flow reactor to reform hydrogen sulfide into hydrogen with the simultaneous recovery of sulfur. Currently, the seven million tons of hydrogen sulfide produced each year as a byproduct of the reaction of sulfurous compounds with hydrogen are processed by Claus reactors into sulfur while wasting the much more valuable hydrogen content through oxidation. The successful development of the process would provide an economical means of dealing with hydrogen sulfide by retaining hydrogen. The Phase I project obtained the highest hydrogen yield ever achieved by a hydrogen sulfide process without the aid of external energy. Furthermore, the project attested that the reactor operates in regimes that eliminate sulfur dioxide. Building on the positive Phase I results; during this Phase II, a small pilot plant will be built and tested forming the basis for designing the commercial reactor with minimal modification. The high price of gasoline and natural gas is partly due to the high cost of extracting sulfurous compounds in the crude oil refining process. This desulphurization process uses hydrogen, obtained mostly from natural gas, to react with the organosulphur species to form hydrogen sulfide. A process that can produce hydrogen as well as sulfur from hydrogen sulfide would save the energy industry hundreds of millions dollars per year in addition to decreasing the cost of gasoline, diesel, and natural gas for consumers. In addition, the process will also eliminate millions of tons of acid-rain-causing sulfur dioxide produced during disposal of hydrogen sulfide.
