摘要： A rotary drum assembly includes separate agglomerating and hardening drums that are rotated independently of each other. The agglomerating drum has a generally cylindrical configuration with an inner cylindrical wall. A scraper is rotatably positioned within the agglomerating drum in spaced relation to the inner cylindrical wall with its axis spaced from the axis of the drum. The scraper has a tubular body portion with a plurality of parallel rows of blades extending radially therefrom. Each of the rows extends lengthwise along substantially the entire length of the scaper body portion and follow a helical path having a single turn about the axis of the tubular body portion. The rows of blades thus make a single convolution about the scraper body portion. Drive means are provided to synchronously rotate the agglomerating drum and scraper with the scraper arranged to rotate at a preselected and different speed relative to the speed of the drum. Agglomerative material is introduced into the rotating agglomerating drum and forms a layer of agglomerative material on the drum inner cylindrical wall. The scraper is rotated in the same direction as the direction of rotation of the agglomerating drum and at a preselected synchronous speed with the agglomerating drum. The rows of parallel blades on the scraper form a plurality of spaced elongated generally longitudinal ridges and valleys in the layer of agglomerative material on the drum cylindrical wall. The ridges have a slight arcuate configuration and form less than a single convolution throughout the entire length of the agglomerating drum. The spaced elongated ridges in the layer of agglomerative material extend lengthwise in the drum substantially parallel to the axis of the drum and serve as longitudinally extending lifters to mix and agitate other particulate agglomerative materials introduced into the drum by lifting portions of the other particulate agglomerative material from the underside of the bed and depositing the material on the upper surface of the bed. This type of mixing promotes the formation of agglomerates having a preselected relatively narrow size range. The synchronous rotation of the scraper removes agglomerative material deposited on the surface of the elongated ridges and valleys formed in the layer of agglomerative material so that the desired ridge and valley configuration is maintained in the layer of agglomerative material.

摘要： An improved process for making metallurgical coke is provided as follows. An effluent slurry consisting essentially of coal extract, solvent and undissolved coal is obtained from the liquefaction of coal by solvent extraction. Solvent is removed from the slurry by distillation to produce a bottoms product which contains non-distillable extract, undissolved coal and residual solvent. The bottoms product is flowable at elevated temperatures below its carbonizing temperature and solidifiable at lower temperatures. The bottoms product is blended with sufficient finely divided hot coaly solids (unsuitable per se for making metallurgical coke) in a hot blending zone which is maintained at a temperature above the softening point of the non-distillable coal extract and below the coking temperature thereof to produce a solidifiable product which, in particulate solidified state, serves as part or all of the feedstock to a coking zone to produce coke suitable for use in a blast furnace.

摘要： The present invention is an improvement in the known process of making a coking feedstock from non-caking or weakly caking coals for slot-type coke ovens wherein the coal is subjected to solvent extraction; and at least the non-distillable extract in the effluent slurry product, after removal of part or all of the solvent, is mixed with carbonaceous solids to serve as a binder therefor. The improvement resides in the use of fluidizer char (which is produced by the low temperature carbonization of coal in a fluidized bed) as the carbonaceous solids. The fluidizer char is preferably mixed with the coal extract slurry (after removal of solvent) in a liquid state at elevated temperatures under pelletizing and non-carbonizing conditions. The pelletized product, after cooling and crushing, is suitable as part or all of the coking feedstock for coke ovens.

摘要： Formcoke suitable for use in a blast furnace is made from a non-caking or weakly caking coal by converting the coal to an agglomeratable material consisting essentially of a blend of the entire product (without separation of extract and undissolved solids) obtained by solvent extraction of the coal in the presence of hydrogen and a suitable amount of hydrocarbonaceous solids. The agglomeratable material is agglomerated under low temperature carbonizing conditions and the agglomerates are thereafter calcined to produce strong formcoke.
