SBIR Phase II: Solid Acid Catalyst with Optimally Distributed Active Sites

这个小型企业创新研究（SBIR）二期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，这将是一种经济可行的替代目前使用有毒液体酸（如HF和H2SO4）的烷基化工艺。这项新技术通过使用一种新型多功能固体酸催化剂，在一个简单的固定床反应器中生产高辛烷值超清洁汽油，将显著降低资本成本和运营费用。该多功能固体酸催化剂在催化活性和长期稳定性方面都明显优于传统固体酸催化剂。使用这种新型催化剂得到的烷基化产物的辛烷值大大高于使用传统固体酸催化剂得到的辛烷值。美国50家炼油厂在其烷基化装置中使用氢氟酸（HF）。新的“绿色”异石蜡烷基化技术是一种经济可行的替代HF催化工艺，可以消除有毒液体酸带来的风险。多功能催化剂有望显著提高收率和选择性，最大限度地减少与液体酸相关的废物副产品和处理问题，并减少二氧化碳排放。

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.
