This Small Business Innovation Research (SBIR) Phase II project aims to develop a practical, cost-effective solid-acid catalyst alkylation technology, which will be an economically viable replacement for current alkylation processes, which use toxic liquid acids such as HF and H2SO4. The new technology will significantly reduce capital cost and operating expenses by using a novel multifunctional solid-acid catalyst that produces high-octane ultra-clean gasoline in a simple fixed-bed reactor. The multifunctional solid-acid catalyst significantly outperforms conventional solid-acid catalyst both in terms of catalyst activity and long-term stability. The octane number of the alkylate product obtained using this new catalyst is substantially higher than that obtained using a conventional solid-acid catalyst. Fifty refineries in the US use hydrofluoric acid (HF) in their alkylation units. The new "green" iso-paraffin alkylation technology is an economically viable alternative to HF catalyzed processes, which would eliminate such risks posed by toxic liquid acids. The multifunctional catalyst promises significantly improves yields and selectivities, minimizing waste by-products and disposal problems associated with liquid acids, and reduces CO2 emissions.

该小型企业创新研究（SBIR）第二阶段项目旨在开发一种实用的、具有成本效益的固体酸催化剂烷基化技术，该技术将成为目前使用有毒液体酸（如HF和H2SO4）的烷基化工艺的经济可行的替代品。这项新技术将通过使用一种新型多功能固体酸催化剂，在简单的固定床反应器中生产高辛烷值超清洁汽油，大大降低资本成本和运营费用。该多功能固体酸催化剂在催化剂活性和长期稳定性方面均显著优于常规固体酸催化剂。使用这种新催化剂获得的烷基化产物的辛烷值显著高于使用常规固体酸催化剂获得的辛烷值。 美国有50家炼油厂在其烷基化装置中使用氢氟酸（HF）。 新的“绿色”异链烷烃烷基化技术是HF催化工艺的经济可行的替代方案，它将消除有毒液体酸带来的风险。该多功能催化剂有望显著提高产率和选择性，最大限度地减少与液体酸相关的废弃副产物和处置问题，并减少CO2排放。
