SBIR/STTR Phase II: Engineered Zeolite Catalyst for Paraffin Alkylation

这个小企业创新研究第二阶段项目旨在开发一种用于石蜡烷基化生产高辛烷值清洁汽油的逐步淘汰技术。传统的烷基化工艺需要大量的腐蚀性液体酸，这可能会通过皮肤接触或吸入造成严重伤害。新的烷基化工艺将从根本上更安全、更清洁，减少有毒化学品的使用和产生。它使用了一种首创的工程沸石催化剂，这种催化剂对环境无害，消除了与液体酸相关的风险，同时生产出质量相当的烷基化油。这种新的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理问题。工程沸石催化剂可以最有效地用于链烷烃和芳族化合物的液相烷基化，例如生产高辛烷值烷基化物，以及工业上重要的石油化学品，例如异丙苯和异丙基苯。

This Small Business Innovation Research Phase II project aims to develop a step-out technology for paraffin alkylation to produce high-octane clean gasoline. Conventional alkylation processes require large volumes of corrosive liquid acids, which can inflict serious injury via skin contact or inhalation. The new alkylation process will be fundamentally safer and cleaner, reducing the use and generation of toxic chemicals. It uses a first-of-a-kind engineered zeolite catalyst that is environmentally benign and eliminates the risks associated with liquid acids while producing alkylate of comparable quality. The new catalyst promises significantly improved yields and selectivities, minimizing waste by-products and disposal problems associated with liquid acids. The engineered zeolite catalysts can be used most effectively for liquid phase alkylations of paraffins and aromatics, such as the production of high-octane alkylate, and industrially important petrochemicals such as cumene and ethylbenzene.
