The invention discloses a preparation method of a catalyst for removing a small amount of H2 from industrial CO gas. The catalyst is prepared by an impregnation method, nickel is taken as an active ingredient, transition metal is taken as an auxiliary agent, and active alumina is taken as a carrier. The catalyst prepared by the method has the advantages that: the preparation method is simple, the active ingredient is uniformly loaded, the obtained catalyst has high catalytic property, and CO and the H2 in the industrial CO gas can be subjected to methanation reaction, so that the content of the H2 in reaction tail gas is less than 400ppm, and the problem of purifying the CO gas in the carbonyl synthesis industry can be effectively solved.

The invention relates to a method for regenerating a loaded detergent (6, 7) from a physical gas scrubbing (T1) process comprises regenerating the detergent removed from a first scrubbing step depending on the remaining amount of loaded detergent to selectively remove the gas components from the raw gas (1). An independent claim is also included for a device for regenerating a loaded detergent from a physical gas scrubbing process comprising a regenerating unit (T2a).

The invention relates to a method for preparing activated carbon by pyrolysis of organic matters, comprising a pyrolyzing device, a reforming device, a drying device, a purifying device, a gas storage device and a high-temperature heat-storage combustion device, wherein pyrolysis reaction is carried out on organic matters by the pyrolyzing device so as to generate combustible gas, tar and coke, the combustible gas enters the drying device after passing through the reforming device so as to dry the organic matters, a part of the purified combustible gas combusts in the direction of a combustion passage of the high-temperature heat-storage burning device so as to generate combustion heat, and simultaneously, the other part of the combustible gas exchanges heat by the heat-storage combustiondevice in the direction of a heat-exchange passage, and then enters the pyrolyzing device for pyrolysis and activation reaction as pyrolyzing and activating medium. In the process of pyrolysis, the coke forms the activated carbon by activation of the combustible gas. The combustible gas generated by pyrolysis is dried by the drying device, and then sensible heat in the gas is fully released; a part of the combustible gas combusts to release heat as the energy source needed in the process of pyrolysis, and the combustible gas is a pyrolysis medium, and is also an activating agent in the process that the coke generates the activated carbon.
