研究了废轮胎裂解油在工业Ni-Mo/Al 2 O3催化剂上加氢处理的最佳工艺方案，以生产高品质的汽油、喷气燃料、柴油和船用燃料等替代运输燃料组分。尽管热解油中烯烃、芳烃、硫和氮的初始含量高，但在360 °C和IOMPa下加氢处理后通过再蒸馏获得的燃料组分满足大多数标准燃料规格。尽管石脑油馏分的辛烷值较低，但该馏分可以直接或催化重整后作为汽油池的组分。渣油馏分经轻度加氢处理或与加氢处理后的酯和脂肪酸（HEFA）调合以降低芳烃含量后可用作喷气燃料。柴油馏分可以与加氢处理的植物油（HVO）混合以满足密度和十六烷指数规格。底渣可用作海上运输的低硫燃料油组分。
The hydrotreating of scrap tires pyrolysis oil over commercial Ni-Mo/Al2O3catalyst was researched for the best processing scheme allowing the production of high-quality alternative transportation fuels components of gasoline, jet, diesel, and marine fuel. Despite the initial high content of olefins, aromatics, sulfur, and nitrogen in pyrolysis oil, fuel components obtained by redistillation after the hydrotreating at 360 °C and 10 MPa met the majority of standard fuel specifications. Although the octane number of the naphtha fraction was lower, this fraction can be used as a component of the gasoline pool directly or after the catalytic reforming. Kerosene fraction can be utilized as jet fuel after the additional mild hydrotreatment or blending with hydroprocessed esters and fatty acids (HEFA) to decrease aromatics content. Diesel fraction can be blended with hydrotreated vegetable oils (HVO) to fulfill the density and cetane index specification. The bottom residue can be utilized as a low-sulfur fuel oil component in marine transportation.
