[0034] Catalyst preparation: according to the mass ratio of 1:(1~20), weigh the main catalyst component and the carbon-based material respectively, and load the main catalyst component on the carbon-based material or with the carbon-based material by traditional impregnation or mechanical mixing The carbon-based material is mixed evenly to form the target catalyst;
[0035] Step 2, catalytic reaction process: under the action of the target catalyst, feed the gaseous raw material into the fixed bed or fluidized bed reactor, and control the reaction parameters as follows: the reaction pressure is normal pressure or micro positive pressure (less than 2kPa), the reaction temperature 750~950℃, reaction space velocity 5~100L / (g cat h), carrying out a constant temperature reaction for 1 to 10 hours in a fixed bed or fluidized bed reactor;
[0036] Step 3. Collection or separation of reaction products: the gas produced in step 2 is collected as synthesis gas; the catalyst reacted in st...
Embodiment 1
[0042] Step 1. Select high-purity methane and CO 2 As gas feedstock, control of methane and CO 2 The feed ratio (in terms of volume flow ratio) of the two is 15:1.
[0043] choose K 2 CO 3 (Analytical pure) as the main component of the catalyst, activated carbon (Gongyi Yuanjie Water Purification Material Co., Ltd., ground and sieved to 100-150 μm particles) as the carbon-based material, weighed and prepared according to the mass ratio of 1:1, and then passed The traditional dipping method will K 2 CO 3 Mix it with activated carbon evenly, dry it at 110°C and use it as the target catalyst.
[0044] Step 2. Under the action of the target catalyst, feed the gaseous raw material into the fixed-bed reactor, and control the reaction parameters as follows: the reaction pressure is normal pressure, the reaction temperature is 850°C, and the reaction space velocity is 15L / (g cat · h), carry out the constant temperature reaction of 5h in the traditional fixed-bed reactor.

Embodiment 2
[0048] The difference from Example 1 is that K in Step 1 of Example 1 2 CO 3 (analytical pure) replaced by Na 2 CO 3 (Analytical pure) as the main component of the catalyst, replace activated carbon with coal pyrolysis semi-coke (big semi-coke from Shenmu County Wuzhou Coal Chemical Co., Ltd., ground and screened to 100-150 μm particles) as carbon-based materials, and other contents are the same as The content of Embodiment 1 is the same, and the effect similar to that of Embodiment 1 can also be achieved.
