Abstract: A process in which lumps of sub-bituminous or lower rank coal are heated to pyrolysis temperatures of up to about 1,000* F. by contact, preferably countercurrent, with an inert hydrogen-poor hydrocarbonaceous heat transfer fluid, preferably a coal-derived oil, thereby transforming the coal to a char product in lump form of upgraded calorific value, such product, moreover, being less pyrophoric than a char product produced by pyrolysis at the same temperatures in an inert gaseous (nitrogen) atmosphere.

Abstract: 1. A PROCESS FOR THE PREPARATION OF LIQUID PRODUCTS FROM COAL WHICH COMPRISES: (A) PREPARING A SLURRY OF FINELY DIVIDED COAL PARTICLES IN A HYDROGENATED AROMATIC HYDROGEN-DONOR SOLVENT HAVING A BOILING POINT IN THE RANGE BETWEEN ABOUT 350*F. AND ABOUT 800*F. IN A SLURRY PREPARATION ZONE; (B) INTRODUCING SAID SLURRY FROM SAID SLURRY PREPARATION ZONE INTO A FLUIDIZED BED COKING UNIT REACTION ZONE; (C) WITHDRAWING OVERHEAD PRODUCTS FROM SAID FLUIDIZED BED COKING UNIT REACTION ZONE AND RECOVERING AN INTERMEDIATE FRACTION BOILING IN THE RANGE BETWEEN ABOUT 350*F. AND ABOUT 800*F. (D) HYDROGENATING SAID INTERMEDIATE FRACTION AND INTRODUCING AT LEAST PART OF THE HYDROGENATED PRODUCT INTO SAID SLURRY PREPARATION ZONE; (E) TRANSFERRING SOLIDS FROM SAID FLUIDIZED BED COKING UNIT TO A BURNER AND BURNING A PORTION OF THE SOLIDS TO PROVIDE HEAT FOR THE PROCESSL AND (F) RECYCLING HOT SOLIDS FROM SAID BURNER TO SAID FLUIDIZED BED COKING UNIT REACTION ZONE.

Abstract: First and second slurries of a particulate coal are formed with low and high boiling fractions of a coal-derived solvent boiling within the range from 300* to 1,000* F., the cut point of the two fractions being from about 500* F. to about 600* F. The slurries are separately liquefied, producing a higher total cylcohexane conversion of the coal than if the coal had been slurried instead in the total coal-derived solvent and liquefied under like conditions.

Abstract: A hydrotreated liquid product from coal is obtained by a process in which liquefaction and hydrotreating zones are operated at essentially the same moderate pressures (1000-2000 psig). Without prior cooling, all the overhead vapor from the liquefaction reactor is admixed with a portion of a light liquid fraction (700* F.) recovered from the liquefaction liquid product, giving a hydrotreating feed having a temperature within a predetermined range. The remaining portion of the light liquid fraction of the liquefaction product is fed to the hydrotreating zone at quench points in the hydrotreating zone downstream from the point of introduction for the admixture, thus utilizing the heats of reaction in the hydrotreating zone to heat the remaining liquid portions (which provide quench to the hydrotreating zone).
Abstract translation: 通过液化和加氢处理区以基本相同的中等压力（1000-2000psig）操作的方法获得来自煤的加氢处理的液体产物。 在没有预先冷却的情况下，来自液化反应器的所有顶部蒸气与从液化产物回收的部分轻液体馏分（700°F）混合，得到温度在预定范围内的加氢处理进料。 液化产物的轻液体部分的剩余部分在加氢处理区域的加氢处理区域的加氢处理区域进料到加料装置的引入点下游，从而利用加氢处理区域中的反应热量来加热剩余的液体 部分（为加氢处理区提供淬火）。
