    • Oxygen and steam are mixed with partially reacted carbonaceous material within a first stage gasification zone to produce synthesis gas. The hot synthesis gas long with additional carbonaceous material is then reacted in a second stage hydropyrolysis zone. The reaction mixture is rapidly quenched and removed from the second stage thereby limiting the total second stage high temperature exposure time from about two milliseconds to about two seconds. The resultant products comprise char, gaseous and liquid hydrocarbons including high yields of benzene, toluene and xylene, and C.sub.1 -C.sub.4 gases. The first and second stages may consist of two separate reactors or two reactors integrated into a single vessel, each utilizing either an upflow or downflow configuration.
    • 在第一级气化区内将氧气和蒸汽与部分反应的碳质材料混合以产生合成气。 然后用另外的碳质材料长的热合成气在第二级加氢热解区中反应。 将反应混合物快速骤冷并从第二阶段除去,从而将总的第二阶段高温暴露时间限制在约2毫秒至约2秒。 所得产物包括炭,气态和液态烃,包括苯,甲苯和二甲苯以及C1-C4气体的高产率。 第一和第二阶段可以由集成到单个容器中的两个单独的反应器或两个反应器组成,每个反应器或两个反应器利用上流或下流构造。
