Example Embodiment
[0060] Example 1
[0061] In this embodiment, the method for preparing methanol synthesis gas and compressed natural gas using coke oven gas and coal as raw materials includes the following main steps: coke oven gas undergoes purification treatment, shift treatment, desulfurization and decarbonization, pressure swing adsorption separation of methane and hydrogen, and methane-rich gas It is pressurized into compressed natural gas, and the coal undergoes coal gasification reaction and purification treatment, mixed with hydrogen, and refined desulfurization treatment to obtain methanol synthesis gas. The schematic block diagram of the process is as follows figure 1 As shown, the specific processing methods for each step are as follows:
[0062] (1) Pretreatment of coke oven gas (i.e. figure 1 Pretreatment of coke oven gas in)
[0063] Adopting the dry purification temperature swing adsorption method, the raw coke oven gas is processed through three stages of rough removal, fine remov...
