摘要： A process for producing calcined coke agglomerates characterized by having a low reactivity to carbon dioxide. The process includes calcining green coal agglomerates at a temperature within the range of 1700.degree. F. to 1950.degree. F. (927.degree. C. to 1066.degree. C.) in a calciner. The agglomerates are exposed to a gaseous atmosphere which before cracking contains not less than 20% by volume of at least one straight chain aliphatic hydrocarbon gas containing one to four carbon atoms. The gaseous atmosphere is preheated to a temperature within the range of 200.degree. F. to 700.degree. F.(93.degree. C. to 371.degree. C.) prior to being introduced into the calciner. Carbon produced when the hydrocarbon gas is cracked, is deposited as vitreous carbon on the surfaces, in the fissures and in the pores of the agglomerates. The calcined coke aggglomerates discharged from the calciner have a reactivity to carbon dioxide of between 2% to 8%.

摘要翻译： 一种用于生产煅烧焦炭附聚物的方法，其特征在于对二氧化碳具有低反应性。 该方法包括在煅烧炉中在1700°F至1950°F（927℃至1066℃）的温度范围内煅烧绿色煤团聚物。 将附聚物暴露于气体气氛下，其在破裂前含有至少一种含有1-4个碳原子的直链脂族烃气体的体积不小于20体积％。 在引入煅烧炉之前，将气态气体预热至200〜700°F（93〜371℃）的温度。 碳氢化合物气体裂解时产生的碳作为玻璃碳沉积在表面，裂隙和附聚物的孔中。 从煅烧炉排出的煅烧焦炭组合物与二氧化碳的反应性在2％至8％之间。
