摘要： This invention concerns a process for cooling the crude coke oven gas drawn from a gas collecting main at a gas temperature of below 20.degree. C. after separating a collecting main flushing liquid fed to a tar separator. To prevent deposists of naphthalene on the cooling tubes of a precooler, the invention provides that the crude coke oven gas is treated before the precooler with tar or a tar-water mixture withdrawn from the tar separator. This effects a partial evaporation of the more volatile components, and the remaining tar or tar-water mixture is again withdrawn before the precooler. A flushing liquid from the edge zone of the tar separator that has definite proportions of low-solids and lighter tar is used in particular and it is fed in parallel with the cooling crude gas in the precooler.

摘要： A method of removing ash components from coals, particularly high-ash content coals, comprises grinding the coal into ground particles and suspending the ground coals in an aqueous alkali carbonate solution. The solution is maintained in a reactor for 45 to 120 minutes at a temperature range of from 250.degree. to 280.degree. C and under a pressure of from 50 to 80 atm in order to cause the CO.sub.2 to be set free by dissociation. The CO.sub.2 is discharged from the reactor by directing an inert gas stream through the reactor and discharging the CO.sub.2 with the gas stream. The suspension is stirred and agitated at elevated temperatures and increased pressures in order to fuse the ashes. The aqueous solution containing the dissolved ash components is then separated from the coal. The removed carbon dioxide is introduced into a solution for reforming the alkali carbonate in order to cause the contents of the solution to become insoluble and separated and the alkali solution to become regenerated. The regenerated solution is then used to continue the operation by forming a further aqueous alkali carbonate solution and ground coal suspension.
摘要翻译：从煤，特别是高灰分煤中去除灰分的方法包括将煤磨成磨碎的颗粒并将研磨的煤悬浮在碱性碳酸碱水溶液中。将溶液在250〜280℃的温度范围和50〜80atm的压力下保持在反应器中45〜120分钟，以通过解离使CO 2释放。通过将惰性气流引导通过反应器并用气流排出CO 2，将CO 2从反应器排出。将悬浮液在升高的温度下搅拌并搅拌并增加压力以使灰烬融合。然后将含有溶解的灰成分的水溶液与煤分离。将去除的二氧化碳引入用于重整碱金属碳酸盐的溶液中，以使溶液的内容物变得不溶解和分离，并使碱溶液再生。然后再生的溶液通过形成另外的碱性碳酸碱水溶液和研磨煤悬浮液来继续操作。
