A recently granted patent (Publication Number: US11872544B2) discloses a modified HZSM-5 catalyst with increased mesopore volume, produced through a specific method. The process involves treating an NaZSM-5 zeolite with alkaline and acidic solutions, followed by drying and calcining to create the modified catalyst. This modified catalyst shows enhanced mesopore volume compared to untreated HZSM-5 catalysts, with mesopores ranging from 2 to 50 nm in diameter. Additionally, the modified catalyst can be formed into extrudates, improving crush resistance, attrition resistance, and mechanical strength when combined with binder materials.
Furthermore, the patent details a method for converting ethylene into larger hydrocarbons using the modified HZSM-5 catalyst extrudate. By contacting a feed stream containing ethylene with the catalyst at specific conditions, over 85% of the ethylene can be converted into products suitable as blend stock for liquid transportation fuel. The feed stream predominantly consists of olefins and alkanes with 2-3 carbon atoms, derived from the cracking of light alkanes through thermal or catalytic cracking processes. The method also includes hydrotreating the resulting products to enhance their quality as blend stock for liquid transportation fuel. Overall, the patent highlights a novel catalyst and method for efficiently converting ethylene into valuable hydrocarbon products for various industrial applications.
