Evaluating Method for Antifoulant of Catalytic Cracking Slurry System

Conditions for antifoulant laboratory evaluation are determined. It has been demonstrated that this evaluating method is feasible in a great deal of experiment with many advantages such as its keen differentiation, its simple equipment, its convenient process and its quickness. The synthesized polyisobutenyl thiophosphonic acids served as slurry antifoulant have antifouling property.
