Problems solved by technology

[0008] The existing hydrogen production conversion furnace is filled with a nickel-based catalyst of a certain particle size and shape in the furnace tube, which often causes uneven loading, causing the raw material gas to drift, resulting in a low conversion rate of the raw material, and the catalyst is prone to carbon deposition and deactivation. operating cycle
In addition, the catalyst with smaller particle size is loaded in the furnace tube, although it can increase the loading amount of the catalyst, increase the number of catalyst active centers, and improve the processing capacity and conversion rate of raw materials to a certain extent, the disadvantage is that the smaller the catalyst size, the furnace The larger the pipe pressure drop, the higher the energy consumption of the feed gas compressor
