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。
- Abstract:
-
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 .
