摘要
橡胶行业是炭黑的主要用户,90%的炭黑产品为橡胶制品所消耗。通过回收处理副产炭黑使之达到常规炭黑的质量要求,扩展其在石化化工行业的应用范围。本实验是通过以高锰酸钾为氧化剂,对炭黑进行回收处理。探讨氧化剂用量、反应温度、反应时间等因素对氧化处理后炭黑的性能影响。通过正交试验及数据处理,综合分析得出氧化处理后炭黑的最优化条件:每10.00 g炭黑的氧化剂高锰酸钾用量为0.2 g,反应温度为90℃,反应时间为20分钟,在此条件下处理后炭黑的吸油值可到达2.965(g/g)。通过电镜扫描、比表面积测定、灰分测定和筛余物对炭黑处理前后的性能进行表征,表征结果表明氧化的原理是正确可取的。为天然气制乙炔副产物炭黑的资源化利用提供了新思路,为石化化工行业绿色低碳发展助力。
The rubber industry is the main users of carbon black,and consumed 90%of the carbon black products for rubber products.Through the recycling of carbon black to conventional carbon black quality requirements,expand the scope of its application in rubber products.This experiment recycled carbon black by potassium permanganate as oxidant.Effects of dosage of oxidant,reaction temperature,reaction time and other factors impact on the performance of the carbon black after oxidation treatment.Through orthogonal experiment and data processing,comprehensive analysis,and the optimal conditions for carbon black after oxidation treatment is that every 10.00 g of carbon black,the dosage of the oxidant potassium permanganate is 0.2 g,the reaction temperature is 90℃and the reaction time is 20 minutes,under the condition of the processing of carbon black oil absorption value reach 2.965(g/g).By electron microscope scanning,mensuration of specific surface area,ash content and screenings for performance of the carbon black before and after the treatment were characterized,and the characterization results show that the oxidation of the principle is correct.This provides a new idea for the resource utilization of carbon black,a byproduct of natural gas to acetylene production,and contributes to the green and low-carbon development of the petrochemical industry.
