N2 - Modified ZSM-22 (TON) zeolites with better stability in the catalytic cracking of n-alkanes are described. The zeolite has 10-membered-rings consisting of pores with a diameter of 0.46 x 0.57 nm. Aluminum was distributed mostly on the outer crystals of TON rods. ZSM-22 was fabricated using microwave-assisted hydrothermal synthesis. The TON zeolites were then treated by silane deposition using the catalytic cracking method. For conventional ZSM-22, the results show high olefin yield with a propylene/ethylene ratio higher than 1.5. However, the conventional catalyst was deactivated strongly after about 150 mins. The modified ZSM-22 shows far better stability with minor deactivation rate ≤ 500 min. This high stability of modified ZSM-22 zeolites can improve the stability of zeolite catalysts in catalytic cracking and in related refining processes such as isomerization and alkylation. This is an abstract of a paper presented at the 23rd Annual Saudi-Japan Symposium on Catalysts in Petroleum Refining and Petrochemicals 2013 (Dhahran, Saudi Arabia 12/2-3/2013).
