Catalytic pyrolysis of waste plastics to produce jet fuel and hydrogen using activated carbon and MgO as catalysts was studied. The effects of catalyst to waste plastics ratio experimental temperature, catalyst placement and activated carbon to MgO ratio on the yields and distributions of pyrolysis products were studied. The placement of catalysts played an important role on the catalytic pyrolysis of LDPE, and the pyrolytic volatiles first flowing through MgO and then biomass-derived activated carbon (BAC) could obtain an excellent result to produce H2 and jet fuel-rich products. The higher pyrolysis temperature converted diesel range alkanes into jet fuel range alkanes and promoted the aromatization of alkanes to generate aromatic hydrocarbons. BAC and MgO as catalysts had excellent performance in catalytic conversion of LDPE to produce hydrogen and jet fuel. 100 area.% jet fuel range products can be obtained in LDPE catalytic pyrolysis under desired experimental conditions. The combination of BAC and MgO as catalysts had a synergy effect on the gaseous product distribution and promoted the production of hydrogen, and up to 94.8 vol% of the obtained gaseous components belonged to hydrogen. This work provided an effective, convenient and economical pathway to produce jet fuel and hydrogen from waste plastics.

废塑料与活性炭和MgO催化热解产生的喷气燃料和氢气。
以活性炭和氧化镁为催化剂，对废塑料进行催化热解制备喷气燃料和氢气。研究了催化剂与废塑料比实验温度，催化剂位置以及活性炭与MgO比对热解产物得率和分布的影响。催化剂的放置在LDPE的催化热解中起着重要作用，热解挥发物先流经MgO，然后从生物质衍生的活性炭（BAC）可获得出色的结果，可生产氢气和富含喷气燃料的产品。较高的热解温度将柴油范围的烷烃转化为喷气燃料范围的烷烃，并促进了烷烃的芳构化以生成芳族烃。BAC和MgO作为催化剂在LDPE催化转化生产氢气和喷气燃料方面具有优异的性能。在所需的实验条件下，可以通过LDPE催化热解获得100面积％的航煤范围产品。BAC和MgO的组合物对气态产物分布具有协同作用，促进了氢的产生，至多94.8vol％的气态成分属于氢。这项工作为从废塑料生产喷气燃料和氢气提供了有效，便捷和经济的途径。所获得的气态组分中至多94.8vol％属于氢。这项工作为从废塑料生产喷气燃料和氢气提供了有效，便捷和经济的途径。所获得的气态组分中至多94.8vol％属于氢。这项工作为从废塑料生产喷气燃料和氢气提供了有效，便捷和经济的途径。
