Description
Technical Field
The invention relates to the technical field of catalysts, in particular to a catalyst carrier.
Background
With the continuous development of the chemical industry, the industry puts forward higher and higher technical requirements on chemical reactions, and particularly in catalytic reactions, the catalytic reactions are expected to have stronger selectivity and better catalytic activity.
At present, the shapes of catalyst carriers mainly comprise strip shapes, hollow cylindrical shapes and clover shapes. The minimum dimension of the solid shape is 1-1.1mm under the requirement of pressure reduction, while the minimum dimension of the hollow product is 3-4mm due to the limitation of strength. The pressure drop of the bed layer has a relation with the size and the shape of the particles, and the smaller the particles are, the larger the pressure drop is. However, the results are reversed from the viewpoint of catalyst activity.
Under the condition that the total amount of active metal materials and the shape of a carrier are not changed, taking a 1.1mm catalyst as a sample, and setting the activity factor of the catalyst to be 1; according to the research data, the catalyst activity factor of 0.7-0.9mm is 4, the catalyst activity factor of 0.2-0.5mm is 14, and the catalytic activity increases with the reduction of the size. The use of a catalyst with smaller particles can reduce the influence of internal diffusion, and is beneficial to improving the surface utilization rate of the catalyst, thereby improving the activity of the catalyst.
The smaller the particle, the greater the pressure drop and the greater the catalytic activity, which are two contradictory aspects that hinder the improvement of the catalyst efficiency.
