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.

该小型企业创新研究（SBIR）第二阶段项目提出开发一种新工艺，该工艺采用超绝热逆流反应器将硫化氢改革为氢气，同时回收硫。目前，每年产生的700万吨硫化氢作为含硫化合物与氢气反应的副产品，通过克劳斯反应器加工成硫，同时通过氧化浪费更有价值的氢气含量。该工艺的成功开发将提供一种通过保留氢气来处理硫化氢的经济手段。第一阶段项目获得了硫化氢工艺在没有外部能源帮助的情况下所获得的最高氢气产量。此外，该项目证明，该反应堆在消除二氧化硫的制度下运行。在积极的第一阶段结果的基础上，在第二阶段，将建造一个小型中试工厂并进行测试，为设计商业反应堆提供基础，并进行最小的修改。汽油和天然气价格高的部分原因是在原油精炼过程中提取含硫化合物的成本高。这种脱硫工艺使用主要从天然气中获得的氢气与有机硫物质反应形成硫化氢。一种可以从硫化氢中生产氢气和硫的工艺，除了降低汽油、柴油和天然气的成本外，每年还将为能源行业节省数亿美元。此外，该工艺还将消除在处理硫化氢过程中产生的数百万吨引起酸雨的二氧化硫。
