Discussion on catalyst drying pressure?
Thread Content
The operating guidelines for hydrocracking units state that the water content in fresh catalysts can range from 5% to 10%. With the optimization and improvement of catalyst production processes, transportation conditions, and loading methods, the water content in catalysts has been significantly reduced at present; it is generally said to be no more than 3%. What is the general situation regarding catalyst drying and dehydration in the units everyone is working in, and what are the catalyst models?
FF46, system pressure ≯4.0Mpa
In the hydrocracking unit industry, the catalyst drying pressure is generally 2.0 MPa. The moisture content in current catalysts is very low; in many cases, there is no water at all during the drying process.
I believe； The lower the pressure during catalyst drying, the better (it is generally controlled at 2.0 MPa, with no strict regulations), but the flow rate must reach a certain level.
