Recent studies show that fast hydropyrolysis (i.e., pyrolysis under hydrogen atmosphere operating at a rapid heating rate) is a promising technology for the conversion of biomass into liquid fuels (e.g., bio-oil and C hydrocarbons). This pyrolysis approach is reported to be more effective than conventional fast pyrolysis in producing aromatic hydrocarbons and also lowering the oxygen content of the bio-oil obtained compared to hydrodeoxygenation (a common bio-oil upgrading method). Based on current literature, various non-catalytic and catalytic fast hydropyrolysis processes are reviewed and discussed. Efforts to combine fast hydropyrolysis and hydrotreatment process are also highlighted. Points to be considered for future research into fast hydropyrolysis and pending challenges are also discussed.
近期研究表明，快速加氢热解（即在氢气氛围下以快速加热速率进行的热解）是一种将生物质转化为液体燃料（如生物油和碳氢化合物）的很有前景的技术。据报道，这种热解方法在生产芳烃方面比传统快速热解更有效，并且与加氢脱氧（一种常见的生物油升级方法）相比，还能降低所得生物油的含氧量。基于当前文献，对各种非催化和催化快速加氢热解过程进行了综述和讨论。还强调了将快速加氢热解与加氢处理过程相结合的努力。也讨论了快速加氢热解未来研究需要考虑的要点和悬而未决的挑战。
