Supercritical catalytic cracking of n -decane over microwave-synthesized hierarchical core–shell nano-Beta@SBA-15 composite zeolite

Key Points

• The aim is to evaluate the efficiency of microwave-synthesized core–shell zeolite in supercritical n-decane cracking.
• Used microwave-synthesized hierarchical core-shell nano-Beta@SBA-15 composite zeolite.
• Conducted supercritical catalytic cracking of n-decane over 15 hours.
• Measured activity, coke formation, and conversion loss.
• Achieved 14.9% higher activity compared to conventional methods.
• Reduced coke formation by 39.7%.
• Maintained only 25.4% conversion loss during the cracking process.
