Examples
Embodiment 1
[0035] use as figure 1 In the process flow shown, the catalyst in the fixed bed is filled with oxide and molecular sieve at a ratio of 1:1, ZnCr oxide in the oxide; the molecular sieve is SAPO-34 molecular sieve, at 400Β°C, 4.0Mpa, 4800h -1 Under the condition of controlling H 2 :CO=1:1, methane content was 10%, reacted for 20 hours, and the reaction product was monitored online by gas chromatography. The reaction results are shown in Table 1.
Embodiment 2
[0037] Adopt the technological process and catalyst packing with embodiment 1; At 400 β, 4.0Mpa, 4800h -1 Under the condition of controlling H 2 :CO=1:1, methane content was 3%, reacted for 20 hours, and the reaction product was monitored online by gas chromatography. The reaction results are shown in Table 1.
