    • Briquettes made from bituminous or sub-bituminous coal or peat are produced by grinding the coal, mixing it with a binder and compacting the mixture. They are then carbonized in a continuous process in a shaft oven. The coal may be predried and the finished briquettes may be preheated, with a subsequent drying and hardening. The carbonization is effected in two stages in an indirectly heated shaft oven, with the evolved gas being taken off about at the mid-height of the oven shaft, processed, and used for heating in the second, high-temperature stage. The flue gases from this high-temperature stage are used for heating in the first stage and for preheating. The second or high-temperature stage is followed by a cooling stage where the gases evolved in the second stage, and mainly comprising hydrogen are used and circulated. The evolved gas in excess is continuously removed from the cooling circuit.
    • 由沥青或次烟煤或泥炭制成的团块通过研磨煤,与粘合剂混合并压实混合物来生产。 然后将它们在轴烘箱中以连续的方法碳化。 煤可以预干燥,并且可以预热完成的团块,随后进行干燥和硬化。 在间接加热的竖炉中分两步进行碳化,放出的气体在烘箱轴的中间高度处被取出,进行处理,并用于第二高温阶段的加热。 来自该高温阶段的烟气用于第一阶段的加热和预热。 第二或高温阶段之后是冷却阶段,其中在第二阶段中放出的气体和主要包含氢的气体被使用和循环。 过量的放出气体从冷却回路连续地移出。

    • Thermally shock-resistant chemically bonded agglomerates suitable for use as a combustible fuel or in a gasification process are produced by:(a) mixing particulate organic material comprising particulate carbonaceous fuel and/or animal excrement (such as dewatered comminuted sewage sludge) with a lignosulfonate, in the presence of water, with application of heat sufficient to maintain the lignosulfonate in fluid form, so as to deposit a film of lignosulfonate over the surface of the particulate material;(b) oxidatively conditioning the lignosulfonate coated particulate material under conditions permitting escape of water present in the mixed particulate material, the conditioning either being in the presence of calcium ions or being followed by mixing the conditioned particulate material with lime; and(c) shaping the resulting free-flowing plastic mixture under pressure, to form the thermally shock-resistant agglomerates.

    • Dry, random size, mine run coal fines are mixed with a concentrated liquor by-product (e.g. ammonium lignin sulfonate liquor, 40-60% solids by weight) of a sulfite paper making process of an amount sufficient to merely wet the coal fines such that they will hold shape when compressed. The wet coal fines are formed into large shapes (e.g. cylindrical logs or rectangular blocks) and the shapes are compressed. The wet coal fines are hopper fed into mold cavities and within the mold cavities are subjected to pressures within the range of 2,000-3,000 psi. The dried shapes are coated with a wax substance.
