Other AbstractProvided are the preparation of a metal lattice-doping catalyst in an amorphous molten state, and the process of catalyzing methane to prepare olefins, aromatics, and hydrogen using the catalyst under oxygen-free, continuous flowing conditions. Such a process has little coke deposition and realizes atom-economic conversion. Under the conditions encountered in a fixed bed reactor (i.e. reaction temperature: 750-1200 °C; reaction pressure: atmospheric pressure; the weight hourly space velocity of feed gas: 1000-30000 ml/g/h; and fixed bed), the conversion of methane is 8-50%. The selectivity of olefins is 30-90%. And the selectivity of aromatics is 10-70%. | 本发明涉及制备一种金属元素晶格掺杂的熔融态无定形催化剂,及其在无氧连续流动条件下催化甲烷制备烯烃、芳烃和氢气的方法,该过程实现了甲烷的零积碳和原子经济转化。在固定床反应模式下,反应温度为反应温度为750-1200℃;反应压力为常压;甲烷的质量空速为1000-30000ml/g/h。甲烷的转化率为8-50%;烯烃选择性为30-90%;芳烃选择性为10-70%;零积碳。该方法具有催化剂寿命长(>100h)、催化剂高温下氧化还原和水热稳定性好、产物选择性高、零积碳、产物易于分离、过程重复性好、操作安全可靠等特点,具有广阔的工业应用前景。
