We selected four dispersants with di erent molecule weight and structure to do parallel experiment and compare their wetting and dispersing e ect and storage stability to solve the problems of ooding and oating in blue automobile nish; and theoretically explained the reason why the e ect is di erent.

The method for the determination of the wetting efficiency of the catalyst in trickle bed reactors is presented.
