| titleOfInvention | The method that a kind of pair of catalyst carries out ex-situ regeneration |
| abstract | The invention belongs to the methods that catalyst technical field more particularly to a kind of pair of catalyst carry out ex-situ regeneration.Specifically comprise the following steps.Specifically includes the following steps: step 1, preparing catalyst regeneration liquid: weigh 3-5 parts of ammonium acid fluoride in parts by weight, 1-3 parts of citric acid, 1-3 parts of sulfuric acid oxygen molybdenum, 1-3 parts of lanthanum carbonate, 1-2 parts of manganese carbonate, 0.5-0.8 parts of emulsifier, 0.5-1 parts of metatungstic acid sodium；(2) 10 parts of distilled water of part raw material in (1) are mixed, is heated, kept the temperature under stirring condition；Step 2 takes parts by weight for 10-20 parts of catalyst, and the segment of 3-5cm is made, is cleaned 3-5 times with 20-25 parts of solvents, then it is soaked in the regenerated liquid prepared in 30-40 parts of step 1, it is put into water bath with thermostatic control and is heated to 200-300 DEG C, isothermal holding 24-36h, holding temperature is 300 DEG C；Catalyst is taken out, is placed in oven and dried, drying temperature is 200-300 DEG C, drying time 12-16h. |
