摘要:
Provided 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%.
