摘要: Abstract Hydrogenation of carbon monoxide has been studied over a series Rh Pt bimetallic catalysts supported by ion exchange on HY, DAHY (dealuminated HY), CaY, HM (H Mordenite) and SiO 2 Al O 3 . The best catalyst in terms high CO conversion selectivity for gasoline with respect to C 5 11 hydrocarbons rich branched-chain was RuPtHY zeolite 2% Ru weight HY. optimum at 240°C 1.5 MPa. Alloy formation examined X-ray diffraction, IR spectroscopy chemisorption H CO. branched chain/straight chain (i/n) ratios were far above those predicted thermodynamics, especially short contact times. type used as the support exerted strong effect fraction i/n ratios.
