Embodiment 1
[0057] In a tubular short-bed multi-stage catalytic reactor (referred to as a fixed-bed reactor), the inner diameter of the reaction tube is 25mm, filled with active components such as oxides of manganese, zinc, and copper provided by the Shanghai Industrial Technology Research Institute. The reaction tube is equipped with a combined member with a height of 150mm composed of wire mesh and porous metal plate, which divides the catalyst filling area into two sections of 100mm and 50mm, and the front and rear sections are also filled with an average equivalent diameter of φ1.5 For the amorphous catalyst, heat transfer oil with an inlet temperature of about 260-280°C is used to enter from the lower part of the fixed-bed reactor in three ways, and flow out from the upper part of the fixed-bed reactor in three ways, and the catalyst in the fixed-bed reactor After the bed temperature rises to the predetermined temperature, the raw material flow preheater is turned on, the main raw mat...

[0059] In a tubular short-bed multi-stage catalytic reactor (referred to as a fixed-bed reactor), the inner diameter of the reaction tube is 25mm, filled with active components such as oxides of manganese, zinc, and copper provided by the Shanghai Industrial Technology Research Institute. The reaction tube is equipped with a combined member with a height of 60mm composed of wire mesh and porous metal plate, which divides the catalyst filling area into two sections of 300mm and 200mm, and the average equivalent diameter of the front and rear sections is φ1.5 and the amorphous catalyst of φ2.25, use heat transfer oil with an inlet temperature of about 260-280°C, enter from the lower part of the fixed bed reactor in three ways, and flow out from the upper part of the fixed bed reactor in three ways, and the fixed bed After the temperature of the catalyst bed in the reactor reaches the predetermined temperature, the raw material flow preheater is turned on, the main raw material is...
Embodiment 3
[0061] In a tubular short-bed multi-stage catalytic reactor (referred to as a fixed-bed reactor), the inner diameter of the reaction tube is 25mm, filled with active components such as oxides of manganese, zinc, and copper provided by the Shanghai Industrial Technology Research Institute. The reaction tube is equipped with a combined member with a height of 200mm composed of wire mesh and metal support packing, which divides the catalyst filling area into two sections of 100mm and 70mm, and the average equivalent diameter of the front and rear sections is φ1.5 The amorphous catalyst and the φ2.25 columnar catalyst use heat transfer oil with an inlet temperature of about 260-280°C, enter from the lower part of the fixed-bed reactor in three ways, and flow out from the upper part of the fixed-bed reactor in three ways After the temperature of the catalyst bed in the fixed-bed reactor reaches the predetermined temperature, the raw material stream preheater is turned on, the main r...
