Abstract
The hydroxyl groups of ZSM-5 and dealuminated ZSM-5 zeolites can be determine by FT-IR spectroscopy technique. All zeolites are having three types of hydroxyl group, i.e. terminal silanol and site defect (3744 cm(-1)), non-framework aluminium (3699 cm(-1)), and framework aluminium (3609 cm(-1)). Intensity of 3609 cm(-1), and 3744 cm(-1) bands of dealuminated ZSM-5 zeolites are decreases. Dealumination of ZSM-5 increases ethylene conversion but decreases gasoline selectivity. The amount of aluminium in the zeolite framework and purity of zeolite has a role in the ethylene conversion to liquid hydrocarbons process.
