Abstract:
1. A method for applying a hydrocarbon protective coating material over a powdered catalyst, the method comprising: a. Combining a hydrocarbon material having a congealing point with a powdered catalyst in a low-shear jacketed blender to form a mixture wherein said catalyst is uniformly dispersed throughout said hydrocarbon, said low-shear jacketed blender being set at a predetermined temperature to maintain said hydrocarbon material in a semi-solid phase; b. Transferring said mixture from said low-shear jacketed blender to a pastillator at a temperature sufficient to maintain said hydrocarbon material in the semi-solid phase; and c. Depositing at a blender end of said pastillator a plurality of drops of said mixture onto a steel belt cooler of predetermined length, and transporting said drops to a discharge end of said pastillator while cooling said drops to a temperature low enough to solidify said hydrocarbon phase to form pastilles.
