Patent number: 10864507Abstract: The present invention provides a process for preparing a zeolite by hydrothermal heating of silica precursor and alumina precursor along with a combination of two structure-directing organic templates, N,N-dimethyl formamide and 1,6-diaminohexane in the presence of an alkali. The use of two structure-directing organic templates, not only reduces the crystallization time but also enables the preparation of more catalytically active ZSM-22 of submicron crystallite size. The present invention also provides a process of preparing a noble metal containing zeolite catalyst for hydroisomerization of long chain n-paraffins.Type: GrantFiled: May 10, 2017Date of Patent: December 15, 2020Assignee: BHARAT PETROLEUM CORPORATION LIMITEDInventors: Ananth Kishore Kumar Sontyana, Kuppusamy Munusamy, Sayanti Ghosh, Shivanand Mukund Pai, Lalit Kumar, Mahesh Wamanrao Kasture, Bharat Lakshman Newalkar
