催化氧化技术处理橡胶干燥尾气VOCs侧线试验

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16 000 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1 400~1 700 mg/m3的条件下，在2 000 h长周期运行期间，NMHC去除率维持在97.0%以上。

Side-stream test on treatment of VOCs from rubber drying tail gasby catalytic oxidation technology

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 2 000 h long-period operation， under the conditions of dry tail gas volume space velocity of 16 000 h-1， catalyst inlet temperature of about 260 ℃， reaction temperature of 260-290 ℃， and NMHC concentration of 1 400-1 700 mg/m3 .
