Incorporation of a coprocessing additive into coal/oil agglomerates

摘要: One method of coprocessing coal and heavy oil uses iron sulphate as a catalyst precursor which, upon decomposition to elemental subsequent transformation pyrite/pyrotite, assists hydrogenation the slurry suppresses coke formation. For high process performance should be dispersed finely possible throughout reactant mixture. In present invention, sulfate is added in form an aqueous wash solution agglomerates after separation ash from agglomerated coal. As remain continuous water phase, good dispersion agglomerate matrix occurs. At this stage unexpectedly strong adsorption FeII ions onto surfaces occurs without any adverse effects on integrity ability separate it selectively by floatation. Furthermore, also results over 94% being transferred agglomerates. This manner addition has been shown elevate advantageously lowest temperature at which formation during coprocessing.
