Why is there a high amount of asphaltenes in the catalytic slurry?
High content of raw material asphaltenes, heavy raw materials, high reaction depth, low agent-to-oil ratio, and poor selectivity
Due to the inherent properties of the raw material, asphaltenes are not easily cracked. The reaction severity is not sufficient.
Is it due to the reaction conditions? Is the reaction depth low? A large reaction depth can easily result in high viscosity of the slurry
