METHOD FOR THE HYDROCONVERSION OF PETROLEUM FEEDSTOCKS VIA A SLURRY TECHNOLOGY ENABLING THE RECOVERY OF METALS FROM THE CATALYST AND FROM THE FEEDSTOCK USING A COKING STEP

摘要

The invention relates to a method for the hydroconversion of heavy petroleum feedstocks, comprising a step of hydroconversion of the feedstock in at least one reactor which contains a catalyst in slurry and enables the recovery of metals in the unconverted residual fraction, in particular those that are not used as catalysts. The method includes a hydroconversion step, a gas/liquid separation step, a coking step, a combustion step, a metal extraction step, and a step of preparing catalytic solutions which are recycled in the hydroconversion step.
