A series of zeolite (LaB, CeB, and PrB) containing rare earth metals lanthanum (La), cerium (Ce), and praseodymium (Pr) were used for transalkylation reaction. The modified beta zeolites were characterized by EDS, XRD, BET, FTIR, and TPD. The surface area and acidities of the zeolite samples modified with various rare earth metals are considerably different. The effect of various process parameters...
The industrially important cymene synthesis was carried out by toluene isopropylation over cerium-exchanged NaX zeolite. The modification of NaX zeolite by cerium exchange was found to enhance the catalytic activity of the zeolite to a considerable extent. The reactions were carried out in a fixed-bed flow reactor at atmospheric pressure with nitrogen as the carrier gas. The reaction conditions were...
