摘要： A catalyst for use in a process for the removal of nitrogen oxides from exhaust gases contaminated with dust in which the process uses ammonia. The catalyst is made of a material which is easily disposable. Furthermore, the catalyst should be completely used up in the catalysis. The catalyst comprises individual ceramic bricks with a porous surface, and passages therethrough for the flow of the exhaust gases. The bricks exhibit a resistance to abrasion which is designed so that the dust of the exhaust gas which flows through the passages erodes the catalyst surface, thereby reactivating the catalyst. The exhaust gas carries the dust and the eroded material along with it.

摘要： A structure made from catalyst for use in the separation of nitrogen oxides from combustion exhaust gases which contain dust. The catalytic structure has plates with spaces therebetween to carry a flow of the exhaust gas therethrough. The catalyst is constructed of individual ceramic plates. The abrasion or wear resistance of the plates is chosen such that the dust in the exhaust gases flowing through the spaces abrades the plate surface at a rate which is at least equivalent to the deactivation of the catalyst surface by action of the nitrogen oxides, which constantly provides a fresh catalyst surface for reaction with the nitrogen oxides. The movement of the exhaust gas through the catalytic structure carries the dust and abraded material along with it and out of the structure.

摘要： A process and apparatus for the dry cooling of coke involves the provision of a vessel having therein first and second zones in full communication with each other. Hot coke from a coking operation is introduced into the first zone and is passed through the first and second zones. Raw coke oven gas from the coking operation is introduced into the first zone, thereby reducing the temperature of the coke, while cleaning the raw coke oven gas to form cleaned coke oven gas. The cleaned coke oven gas is removed from the first zone, cooled, and then directly or indirectly utilized as a heat carrier gas introduced into the second zone to therein further reduce the temperature of the coke. The thereby further cooled coke is removed from the second zone.

摘要： Coke is produced from coal by coking the coal, and optionally by drying and/or preheating the coal prior to coking, and further optionally by dry cooling the coke subsequent to coking. At least the coking step is achieved in a pressure tight container which may be a transportable or tippable container. The coking step is performed in the container by conducting a gas through the container in direct or indirect heat exchange relationship with the coal and forming coke. The coking step includes a phase of lump coke formation achieved by heating the coal in a temperature range of between approximately 250.degree. and 600.degree. C. by indirect heat exchange only.

摘要： Apparatus for the production of ammonia synthesis gas by the catalytic cracking of coke oven gas in the presence of water vapor and air is disclosed. The apparatus includes concentric inner and outer pipes, a first annular reaction zone between the pipes and a second reaction zone inside the inner pipe, both zones containing a catalyst. The purified coke oven gas along with air and water vapor is introduced into the interior of the outer pipe, i.e., into the first reaction zone at one end. The gas flows along the length of the pipes and then into the inner pipe, i.e., the second reaction zone, through a number of openings in the end of the inner pipe opposite the end of the outer pipe where the coke oven gas was initially introduced. The gas then flows along the length of the inner pipe to the opposite end where the cracked gas is removed.

摘要： Flue gas discharged from a recuperator or regenerator of a coke oven battery has the steam thereof removed by means of a direct or indirect cooling and condensation operation. After the steam is removed from the flue gas it is then passed through a coke dry cooling plant in direct contact with hot coke therein to form dry cooled coke while simultaneously increasing the temperature of the flue gas. The flue gas is then passed through a coal preheating plant to directly contact and dry and preheat moist coking coal contained therein. The entire system is open, such that a given quantity of the flue gas passes only once through the system. When the temperature of the flue gas as received from a coke oven battery is extremely high, then the flue gas may be subjected to a partial cooling operation prior to the cooling and condensation operation. Further, a portion of the heat of the flue gas, after the discharge thereof from the coke dry cooling plant and prior to the introduction thereof into the coal preheating plant, may be used to generate steam and/or electricity.

摘要： A heat carrier gas is passed through a coke dry cooling plant in direct contact with hot coke therein to form dry cooled coke while simultaneously increasing the temperature of the heat carrier gas. The heat carrier gas is then passed through a coal preheating plant to directly contact and dry and preheat moist coking coal contained therein. The entire system is open, such that a given quantity of the heat carrier gas passes only once through the dry cooling plant and the coal drying and preheating plant. The heat carrier gas may be a flue gas which is passed directly to the coke dry cooling plant without any preliminary pretreatment, and preferably is a flue gas which is supplied directly from a regenerator or recuperator of a coke oven battery. Alternatively, the heat carrier gas may be in the form of a fuel gas which is inert with respect to the hot coke, for example a waste gas or stack gas supplied from an adjacent metallurgical installation, such as a steel mill.
