摘　　要：三聚氯氰的合成主要采用氯氰单体在催化剂活性炭作用下高温聚合反应而得。探究三聚氯氰制备过程中,活性炭催化剂的失活机理,对延长催化剂反应周期、提高生产效率具有重要意义。准备SPTGA型分析仪等实验设备,通过设置干燥脱水时间以及N_(2)流量条件等10项测试条件,完成三聚氯氰制备过程中活性炭催化剂失活机理实验。测试表明,三聚氯氰制备过程中活性炭催化剂的失活与其表面微孔孔径、制备环境酸碱度、金属物质含量存在直接关系,需要控制这些因素才能发挥活性炭催化剂在三聚氯氰制备过程中的更高效能。The synthesis of cyanuric chloride is mainly achieved by high-temperature polymerization of cyanuric chloride monomer under the action of catalyst activated carbon.Exploring the deactivation mechanism of activated carbon catalysts in the preparation process of cyanuric chloride is of great significance for prolonging the catalyst reaction cycle and improving production efficiency.Prepare experimental equipment such as SPTGA analyzer,and complete the deactivation mechanism experiment of activated carbon catalyst during the preparation of melamine by setting 10 test conditions such as drying and dehydration time and N_(2)flow rate.Tests have shown that the deactivation of activated carbon catalysts during the preparation of melamine is directly related to their surface micropores,preparation environment acidity,and metal content.It is necessary to control these factors in order to fully utilize the more efficient performance of activated carbon catalysts in the preparation of melamine.
