Problems solved by technology

[0004] In addition, there are other similar methods that are used for reference in the measurement of the solid content of oil slurry, such as "GB / T508-91 Determination of Ash Content in Petroleum Products (Gravimetric Method)", which has a cumbersome operation process, long analysis time, and The operating temperature of 800 °C used will damage the microstructure of the catalyst to a certain extent, which is not conducive to the further study of the formation mechanism of the catalyst powder; "GB / T511-88 Determination of mechanical impurities in petroleum products and additives (gravimetric method)", This method consumes a large amount of solvent, the operation process is cumbersome, and the analysis time is long. The main reason is that the coke on the surface of the catalyst cannot be completely washed off by the organic solvent, and the result does not fully represent the content of the catalyst powder in the oil slurry.
[0005] From above-mentioned prior art, because do not have suitable treatment oil slurry charring burning device, make the mensuration of solid content in oil slurry not accurate enough at present, and because the destruction of catalyst microstructure, can't make the formation mechanism of catalyst powder further research

Abstract

An oil slurry burning apparatus for carbonizing it is composed of machine casing, partition, insulating jacket, gas inlet and outlet tubes, insulating layer, heating jacket, heating tube, specimen box, top cover and connecting pipes. Its advantages are no need of solvent, simple operation, and no damage to microscopic structure of catalyst.

Description

Technical field [0001] The invention relates to an oil slurry carbonization burning device and a method of use. Background technique [0002] The oil slurry of the catalytic cracking process contains catalyst powder and trace ash. The content of the catalyst powder in the oil slurry is related to the strength of the catalyst and the separation efficiency of the cyclone separator. With the continuous improvement of petrochemical refining technology, the solid content in the oil slurry, that is, the catalyst powder, has been significantly reduced; at the same time, with the continuous expansion of the use of the oil slurry, the requirements for the solid content of the oil slurry have become more and more stringent. The analysis and determination of pulp solid content also put forward higher requirements. [0003] At present, the commonly used method for determining the solid content of oil slurry is the solvent dilution centrifugal method. This method has a large human error and i...
