    • A process for producing carbon black by a furnace method wherein carbon black is produced in a reaction system comprising a first zone where a mixture of a fuel hydrocarbon and an oxygen-containing gas is burned to form a high temperature combustion gas atmosphere, and a starting oil material is continuously supplied to the high temperature combustion gas atmosphere, and a second zone, as a down-stream zone subsequent to the first zone, where a carbon black-suspended hot gas formed in the first zone flows in and is rapidly cooled, characterized in that carbon dioxide or carbon dioxide and steam are supplied to the first zone and/or the second zone to bring the carbon dioxide concentration in the second zone within a range of from 15 to 70% by volume, and the retention time of the carbon black-suspended hot gas in the second zone is at least 0.2 second.
    • 一种通过炉法生产炭黑的方法,其中在包括燃料烃和含氧气体的混合物的第一区域的反应系统中产生炭黑以形成高温燃烧气体气氛,以及起始 将油料连续供给到高温燃烧气体气氛中,第二区域作为在第一区域之后的下游区域,其中形成在第一区域中的炭黑悬浮的热气体流入并被快速冷却, 其特征在于,将二氧化碳或二氧化碳和蒸汽供应到第一区域和/或第二区域以使第二区域中的二氧化碳浓度在15体积%至70体积%的范围内,并且保留时间 第二区域中的炭黑悬浮的热气体为至少0.2秒。
