A method for introducing fine and coarse additives for the hydroconversion of heavy hydrocarbons

摘要

A procedure for hydrocracking in suspension of a heavy Hydrocarbon feedstock in a reactor of hydrocracking in suspensionUnderstanding the procedure: introduce a First Additive in the raw material upstream of a preheating Heat exchanger to form a raw material Loaded Fine,Understanding the Additive of Fine particles with a distribution of Particle sizes less than 500 micrometers.Separately introduce a Second Additive raw material charged down a fine current charge Pump Power and upstream of the Reactor of hydrocracking in suspension phaseThe Second Additive comprising Coarse particles having a median particle sizes between 400 and 2 micrometers.000 micrometres, and withdraw The reaction products in the Reactor of hydrocracking in suspension phase.
