| Abstract: | The process on the nitrogen removal by static absorption of caustic nitrides from CGO with W-SBA-15 molecular sieve absorbent in PetroChina Fushun No.2 Refinery was tested,and the impact of process conditions on the denitrification was studied.The results showed that,at the conditions of 140 ℃C ab sorption temperature,40 minutes absorption time and 0.05 oil to absorbent ratio,the optimum denitrification rate is 45.1％,the static absorption capacity is 8.13 mg/g.The nitrogen removal rate of the mesoporous molecular sieves after regeneration is higher than 38％. |
