Application of modified β zeolite in the direct synthesis of LPG from syngas
The application of Pd-β in the LPG (Liquefied Petroleum Gas) synthesis from syngas has been investigated, the results showed that there exists an synergistic effect between Pd-β and Pd-Zn-Cr in the LPG synthesis from syngas, the SiO2/Al2O3 ratio of Pd-β has an largely influence on the stability of Pd-Zn-Cr/Pd-β catalysts for syngas to LPG. As the SiO2/Al2O3 ratio increasing from 37 to 300, CO conversion decreases from 78.7% to 72.2%; however, the catalytic stability of Pd-Zn-Cr/Pd-β catalysts is largely improved. The reaction of LPG synthesis from synthesis gas over Pd-β/Pd-Zn-Cr hybrid catalyst follows the route: synthesis gas to LPG via methanol or DME.
