Syngas conversion to ethane over metal-zeolite catalysts

Abstract Synthesis gas is selectively converted to ethane over a dual-functional catalyst comprised of HZSM-5 zeolite ( SiO 2 Al 2 O 3 = 70 ) containing Cr, Zn, and Al in the atomic ratios 1:1:1 (zeolitic Al) at 343–482 °C, 100 atm, and 500 hr−1 GHSV. Ethane selectivities as high as 83 wt% were obtained. The roles of metal and zeolite are defined and the reaction path is elucidated.
