Embodiment 1
[0023] The iron-based catalyst preparation process is as follows:
[0024] Weigh 10 g of corn cob powder into a crucible, then transfer it to a muffle furnace and roast at 700°C for 3 hours, take it out after cooling to room temperature, and store it for future use. After the roasting treatment, the above-mentioned powder and commercial molten iron (black powder, specific surface area 10m 2 / g) was weighed according to the mass ratio of 5:95, then transferred to a mortar and ground for uniformity, and then pressed into tablets and sieved to obtain a 150-mesh iron-based catalyst.
[0025] The composition of the prepared iron-based catalyst is shown in Table 1. Effective promoters such as K, Ca, Mn, Mg, and Si all exist in the iron-based catalyst. The appearance of iron particles is as figure 2 As shown, the prepared catalyst is mainly composed of uniformly dispersed iron particles of about 20nm. From other chemical analysis, the active phase of iron is mainly composed of ir...

[0033] The iron-based catalyst preparation process is as follows:
[0034] Weigh 10 g of corncob powder into a crucible, then transfer it to a muffle furnace and roast at 600°C for 3 hours, take it out after cooling to room temperature, and store it for future use. After the roasting treatment, the above-mentioned powder and commercial molten iron (black powder, specific surface area 10m 2 / g) was weighed according to the mass ratio of 10:90, then transferred to a mortar and ground for uniformity, and then pressed into tablets and sieved to obtain a 200-mesh iron-based catalyst.
[0035] The composition of the prepared iron-based catalyst is shown in Table 1. Effective promoters such as K, Ca, Mn, Mg, and Si all exist in the iron-based catalyst, and the content of alkali metal promoter K is as high as 3.9%.
