| 英文摘要 | synthesis of liquefied petroleum gas (lpg) via dimethyl ether (dme) from syngas was carried out in a two-stage reaction system, where syngas was transformed to dme in the first stage over the cu-zn-al/zsm-5 catalyst and then to hydrocarbons in the second stage over the pd-y catalyst. co conversion and lpg selectivity were dominated by the first and second stage, respectively. co conversion could be kept at a high level through the gradual increase of reaction temperature of the first stage, although there was a slight deactivation for the cu-zn-al/zsm-5 catalyst. lpg selectivity in hydrocarbons was more than 75% due to the proper pore size of y zeolite and the presence of hydrogen. coke deposition on y zeolite was the reason for the decrease of lpg selectivity, but fortunately the selectivity of lpg could be recovered to a great extent by coke burning.
