摘要: 以硅胶为载体,利用等体积浸渍法负载杂多酸制备3种不同负载型杂多酸吸附剂,采用傅里叶红外光谱和氮气吸附-脱附法对吸附剂负载状态进行了表征。将制备的负载型吸附剂用于焦化蜡油中碱性氮化物的脱除,考察了负载量、反应时间、反应温度和剂油质量比对焦化蜡油脱氮率的影响。结果表明,磷钨酸负载质量分数为40%、反应温度为50℃、反应时间为50min、剂油质量比为1:4的条件下,负载型杂多酸吸附剂能有效脱除焦化蜡油中的碱性氮化物,脱氮率达到89.07%,脱氮油收率达95.54%.

Abstract: Three different heteropoly acid adsorbents were prepared with silica gel as support by impregnation method and characterized by infrared spectrum and N2 adsorption-desorption methods. The supported adsorbents were used for the removal of basic nitrogen compounds in CGO. The optimum conditions for denitrification of CGO were studied by examining the effect of reaction time,reaction temperature,oil ratio and loading mass. It was shown that when phosphotungstic acid loading mass was 40%,the reaction temperature was 50℃,the reaction time was 50min and mass ratio of adsorbent to oil was 1:4,Best performance of the adsorbent was observed,with a denitrification rate of 89.07% and a denitrification oil yield of 95.54%.

Key words: support, heteropoly acid, adsorption, basic nitrogen compounds
