Description: A method at a high temperature modulated by varying the pressure of the acid catalyst is distributed belongs preparation, modification and application of the catalyst art.By varying the pressure to a high temperature under an acid catalyst distribution modulation. The present invention under high-temperature conditions by varying the pressure distribution of an acid catalyst to achieve modulation, specifically: in the range of 0.1 ~ 10MPa pressure, a certain size of the molecular sieve catalyst, in an inert gas at a temperature of 200 ~ 800 ℃ Treatment 1 ~ 4h, a pressure modulation by varying the amount of acid and the acid strength of the catalyst. Beneficial effects and benefits of the present invention is achieved, the modulation amount of acid catalyst and acid strength, just at a certain temperature heat treatment can be achieved by changing the pressure, with time-consuming short, simple, easy, effective and environmental friendliness. Mainly suitable for fine chemicals and oil.
