Drying and dehydration of catalysts
Thread Content
Process conditions for drying the catalyst inside the reactor: Medium used for catalyst drying: nitrogen. Operating pressure: 0.5–2.5 MPa. Volume of gas circulated: full capacity of the circulation compressor. Rate of temperature increase: ≤20°C/h. Bed temperature: 200–250°C. Drying is carried out under these conditions until the water release rate per hour reaches a certain level
