Composition including peptization agent
A composition is provided for use in solid catalyst manufacture including an inorganic oxide and a peptization agent, for forming solid catalyst materials having improved structural properties are provided. The peptization agent includes one or more oxidized disulfide oil (“ODSO”) compounds. These ODSO compounds as peptization agents serve to improve the adhesion characteristics of the binder material, and as a result increase the particle strength of the final catalyst particles.
