SBIR Phase I: A New Hydrogen Source From Toxic Hydrogen Sulfide

这个小企业创新研究（SBIR）第一阶段项目的目标是开发一种从有毒硫化氢（H2S）中生产有价值的氢和硫的工艺。目前的商业技术将H2S转化为水和硫，从而失去了宝贵的氢来源。硫聚合机制提出的过程已经确定了使用计算化学。结果，确定了新的硫聚合剂，并将在本工作中进行实验验证。新的催化剂载体也已确定，并将进行评估。用于除硫的氢气消耗量占总氢气需求量的25%至40%。因此，将H2S中的氢气在炼油厂内完全循环利用可以显著降低资本和运营成本。

This Small Business Innovation Research (SBIR) Phase I project will target the development of a process to produce valuable hydrogen and sulfur from toxic hydrogen sulfide (H2S). Current commercial technology converts H2S into water and sulfur, thereby losing a valuable source of hydrogen. Sulfur polymerization mechanisms for the proposed process have determined using computational chemistry. As a result, new sulfur polymerization agents were identified and will be verified experimentally in this work. New catalyst supports have also been identified and will be evaluated. The amount of hydrogen consumption to remove sulfur represents from 25 to 40% of the total hydrogen requirement. Hence, putting the hydrogen in H2S on total recycle within a refinery could significantly reduce capital and operating costs.
