Patent number: 11066491Abstract: According to one or more embodiments, cationic polymers may be produced which include one or more monomers containing cations. Such cationic polymers may be utilized as structure directing agents to for mesoporous zeolites. The mesoporous zeolites may include micropores as well as mesopores, and may have a surface area of greater than 350 m2/g and a pore volume of greater than 0.3 cm3/g. Also described are core/shell zeolites, where at least the shell portion includes a mesoporous zeolite material.Type: GrantFiled: July 21, 2020Date of Patent: July 20, 2021Assignees: Saudi Arabian Oil Company, King Abdullah University of Science and TechnologyInventors: Yu Han, Qiwei Tian, Xinglong Dong, Zhaohui Liu, Jean-Marie Basset, Youssef Saih, Miao Sun, Sohel Shaikh, Wei Xu
