摘要:
The invention relates to a method for producing shaped, activated charcoal. According to the method, after being ground, carbon-bearing material, or a mixture of several carbon-bearing materials are rendered homogenous with a binding agent which contains water, or a mixture of several binding agents, at least one of which contains water. The mixture of carbon-bearing material and binding agent is then formed into shaped bodies. According to the invention, in order to consolidate the grain formation, these are dried until they exhibit a maximum total water content of 3% by wt. in relation to the shaped body. The shaped bodies which have been formed and dried in this manner are then subjected to a carbonization and subsequently a gas activation process.
摘要:
A granulation water control apparatus for a granulating machine used in a granular fertilizer production process and its granulation water control method. A particle size weight distribution of a semi-fabricated fertilizer discharged from the granulating machine is calculated, and a central particle size of the particle size weight distribution is calculated. The calculated central particle size and a previously set target central particle size are compared, and if they do not agree, a quantity of the granulation water to be charged into the granulating machine is calculated in accordance with a difference between the calculated central particle size and the target central particle size and the past statistical data.
摘要:
An improved process is provided for the manufacture of a catalytically-active carbonaceous char capable of rapidly decomposing hydrogen peroxide in aqueous solutions. The process of the invention uses a low temperature carbonization and extensive oxidation of a bituminous coal or bituminous coal-like material followed by exposure to a nitrogen-containing compound at high temperatures during the initial calcination and/or activation. The resultant catalytically-active chars have the ability to rapidly decompose aqueous solutions of hydrogen peroxide and are useful for catalytic conversion of H.sub.2 S, SO.sub.x, NO.sub.x, chloramines, and/or peroxides in liquid and/or gaseous streams.
摘要:
Carbon black reactor effluent is quenched and is then passed to a carbon black preagglomeration zone prior to being passed through the tubes of a shell-tube in direct heat exchange zone. The preagglomeration zone produces larger particles of carbon black, thereby minimizing deposits of carbon on the inner peripheries of the tubes of the heat exchange zone so as to maintain the desired high heat transfer efficiency.
摘要:
In a furnace system for producing carbon black, a primary quench fluid is injected into the combustion products from the furnace to produce effluent. The effluent is passed through a trim quench chamber containing a tubular member. The tubular member has an internal flow path therethrough and is positioned in the housing defining the quench chamber to form an outer flow path therebetween. Part of the effluent flowing through the quench chamber passes through the internal flow path while the remainder passes through the outer flow path. Quench liquid is introduced into the quench chamber for initial contact with substantially only the portion of the effluent passing through the internal flow path.
