Embodiment Construction
[0031] Below in conjunction with embodiment the present invention is further described.
[0032] A method for determining the solid content of catalytic cracking oil slurry, comprising the steps of:
[0033] (1) select the plastic centrifuge tube of 50mL for use, and weigh the centrifuge tube;
[0034] (2) Pretreat the catalytically cracked oil slurry, preheat the catalytically cracked oil slurry to 60°C, and stir at a constant temperature for 15 minutes, so that the solids in the oil slurry are evenly distributed in the oil slurry, and avoid particle settling. Particle distribution is uneven.
[0035] (3) Take 10g of the oil slurry treated in step (2) and add it to the weighed centrifuge tube, and add diluent toluene to dilute, the amount of toluene added is the sum of the amount of toluene and oil slurry to reach the 40mL scale line, then stir to make it evenly mixed, put the centrifuge tube into the centrifuge for centrifugation operation, the centrifugation operation con...
