负载型杂多酸脱除焦化蜡油中碱性氮化物
Removal of basic nitrogen compounds in coker gas oil by supported heteropoly acid
摘要
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 inCGO. 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%.关键词
