Embodiment 1
[0019] Butanol Oxylation Catalyst Mother Liquor Catalyst Activity of Butanol Oxylation Catalyst of Butyl Octanol Unit Dropped Suddenly, Shown as Operating Load Decreased, At the same time, the partial pressure of propylene, hydrogen and carbon monoxide rose obviously. Catalyst poisoning, after testing the activity of the catalyst in the reactor, it is determined that the activity has been reduced to 26%.
[0020] For above-mentioned situation, adopt following method to butanol oxo synthesis catalyst chemical regeneration:
[0021] (1) remove free state S in butanol oxo synthesis catalyst mother liquor 2- and Cl - , the specific steps are: under the oxo-butanol carbonylation reaction process conditions in the non-production state, the regenerant A is uniformly mixed with the oxo-butanol oxo synthesis catalyst mother liquor, and the free state the S 2- and Cl - Carry out washing, make in the catalyst mother liquor, produce butyl octanol carbonylation catalyst phase and regen...
Embodiment 2
[0027] The catalyst activity of the butanol oxo synthesis catalyst mother liquor in the butanol unit suddenly decreased, which was manifested by a decrease in operating load, and at the same time, the partial pressure of propylene, hydrogen, and carbon monoxide increased significantly. Catalyst poisoning, after testing the activity of the catalyst in the reactor, it is determined that the activity has been reduced to 28%.
[0028] For above-mentioned situation, adopt following method to butanol oxo synthesis catalyst chemical regeneration:
[0029] (1) remove free state S in butanol oxo synthesis catalyst mother liquor 2- and Cl - , the specific steps are: under the oxo-butanol carbonylation reaction process conditions in the non-production state, the regenerant A is uniformly mixed with the oxo-butanol oxo synthesis catalyst mother liquor, and the free state the S 2- and Cl - Carry out washing, make in the catalyst mother liquor, produce butyl octanol carbonylation cataly...
Embodiment 3
[0035] Some elements of the poisoned butanol carbonylation catalyst mother liquor exceeded the standard, including S: 0.137%, Na: 62.79ppm, Ni51.2ppm, Fe: 24.77ppm, S exceeded the standard by 1370 times, and Cl exceeded the standard by 4.5 times.
[0036] For above-mentioned situation, adopt following method to butanol oxo synthesis catalyst chemical regeneration:
[0037] (1) remove free state S in butanol oxo synthesis catalyst mother liquor 2- and Cl - , the specific steps are: under the non-production state oxo-oxo reaction process conditions, the regenerant A is uniformly mixed with the oxo-catalyst mother liquor of octyl-butanol, and the free state the S 2- and Cl - Carry out washing, make in the catalyst mother liquor, produce butyl octanol carbonylation catalyst phase and regeneration agent A phase layering, S 2- and Cl - Transfer to the regeneration agent A phase, retain the butyl-octyl alcohol oxo catalyst phase, and drain the regeneration agent A phase, and the...
