摘　　要：采用纳米涂层技术和活性组分分散技术制备出挥发性有机物(VOCs)催化氧化催化剂。以10万t/a丁苯橡胶装置干燥尾气为研究对象,利用集成的侧线试验评价装置对该催化剂进行了催化性能、工况适应性、非甲烷总烃(NMHC)去除率的评价,以及长周期运行试验。结果表明:在干燥尾气体积空速为16000 h^(-1),催化剂入口温度约为260℃,反应温度为260~290℃,NMHC质量浓度为1400~1700 mg/m^(3)的条件下,在2000 h长周期运行期间,NMHC去除率维持在97.0%以上。The volatile organic compounds(VOCs)catalytic oxidation catalysts were prepared by adopting nano-coating technology and active component dispersion technology.The catalytic performance,adaptability to operating conditions,non-methane hydrocarbon(NMHC)removal rate and long-period operation tests of the catalyst were evaluated by using the integrated side-stream test evaluation device with the dry tail gas of a 100 kt/a styrene-butadiene rubber unit.The results showed that the NMHC removal rate could be maintained above 97.0%during the 2000 h long-period operation,under the conditions of dry tail gas volume space velocity of 16000 h^(-1),catalyst inlet temperature of about 260℃,reaction temperature of 260-290℃,and NMHC concentration of 1400-1700 mg/m^(3).
