Abstract
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.
