Process for the conversion of lignin to liquid hydro-carbons comprising: subjecting the lignin to hydrogenolysis in the presence of at least one hydrogenolysis catalyst, at a temperature ranging from 250° C. to 350° C., preferably ranging from 290° C. to 320 ° C., so as to obtain depolymerized lignin; subjecting said depolymerized lignin to hydrotreating so as to obtain a mixture of liquid hydrocarbons. Said liquid hydrocarbons can be used as such (biofuels) for the production of reformulated gasolines, or they can be used for the production of gasolines or of gas oils through conventional refining processes.
将木质素转化为液态烃的过程包括:在至少一种氢解催化剂的存在下,将木质素暴露于氢解作用,温度范围在250°C至350°C之间,最好在290°C至320°C之间,以获得降解的木质素;将所述降解的木质素进行加氢处理,以获得液态烃的混合物。这些液态烃可以直接用作生物燃料(生物燃料),用于生产改性汽油,或者可以通过传统的精炼工艺用于生产汽油或柴油。
