摘要
应用生物质衍生焦炭对聚丙烯挥发分进行催化重整,分别将Na2CO3、CaO和Fe2O3负载在炭中以实现催化效果的强化。通过对比液相产率、产气率可以看出:生物质炭对聚丙烯挥发分有显著的催化重整效果,温度为750℃时液相产率为11.80%,较无催化时下降了13.60%。Na2CO3作用下随着温度的升高,750℃时液相产率为8.66%,较聚丙烯单独热解时下降了16.74%,产气率最高可达50.86%。负载Fe基的生物质衍生焦炭,在高温阶段对聚丙烯热解挥发分的降解效果不明显,液相产率750℃时为11.64%,产气率为47.91%。添加CaO,随着热解温度的提升液相产率最低可至9.36%,较单独热解时下降了16.04%,产气率最高可达50.18%。在本实验条件下,生物质炭中负载Na基对聚丙烯挥发分催化重整效果最为明显。
Biomass-derived coke was used to catalyze and crack polypropylene volatile matter.Na2CO3,CaO and Fe2O3 were respectively loaded in carbon to enhance the catalytic effect.By comparing the liquid phase yield and gas production rate,it can be seen that the biomass charcoal has a significant catalytic reforming effect on polypropylene volatile.The liquid phase yield is 11.80%at 750℃,which is 13.60%lower than that without catalysis.With the increase of temperature under the action of Na2CO3,the liquid phase yield at 750℃was 8.66%,16.74%lower than that of polypropylene pyrolysis alone,and the highest gas production rate was 50.86%.The degradation effect of Fe-based biomass-derived coke on polypropylene pyrolysis volatile is not obvious at high temperature.The liquid phase yield is 11.64%at 750℃and the gas production rate is 47.91%.When CaO is added,the liquid phase yield can reach 9.36%with the increase of pyrolysis temperature,which is 16.04%lower than that of pyrolysis alone,and the highest gas production rate can reach 50.18%.Under the experimental conditions,the effect of Na-based additives loaded in biomass char on catalytic reforming of polypropylene volatile matter is the most obvious.
