Abstract:
In the process for conversion of particulate carbonaceous material into vaporizable products by first deashing the particulate carbonaceous material by making a vigorously stirred slurry of said material in water, adding 0.5 to 35 weight percent of a hydrophobic free flowing organic oil in order to selectively coat and cause agglomeration of said particulate carbonaceous material leaving it free of particles of ash, separating said agglomerate, dewatering and drying said agglomerates, and feeding said agglomerate to a reaction zone for reaction with reducing gas at a temperature of 600-900.degree. F. and a pressure of 100-5000 psi and residence time of one second to three hours to convert it into vaporizable product,the improvement comprising adding the step of mixing an oil-soluble form of liquefaction catalyst or catalyst precursor selected from compounds of the metals, iron, molybdenum, nickel, cobalt, tin and tungsten, into the above hydrophobic free flowing organic oil that is to be added to the water slurry of the particulate carbonaceous material to coat its surface and cause its agglomeration.
