摘要
第二代生物燃料和化学品可采用加氢转化、加热裂化或催化裂化、生物质气化和合成气转化等几种方法生产。石油炼制厂商在考虑采用生物原料时,面临着产品"能量密度"、生物质原料是否为废料或非人畜食物来源,以及如何充分利用现有设施等问题。采用加氢转化和加热裂化或催化裂化工艺,可在石油炼制过程中以动物脂肪和植物油为原料,生产可与石油相容的生物燃料,同时使炼厂降低碳排放。应实现生物炼制能力与石油炼制操作的一体化,从而使生物炼制业和传统石油炼制业都实现可持续发展。
The second-generation bio-fuels and chemicals can be produced using several methods such as hydroconversion,thermal or catalytic cracking,biomass gasification and syngas conversion.Specific goals and challenges exist for petroleum refiners considering the use of biofeeds ,such as producing products with high energy densities ,whether or not the biofeeds are otherwise wastes or sources of food for humans and animals and how use of existing facilities can be maximized.Hydroconversion and thermal or catalytic cracking tech- nologies utilize animal fats and vegetable oils in refinery operations.These processes can produce petroleumcompatible renewable fuels while simultaneously allowing refineries to achieve the ultimate goal of reducing their carbon footprints.Bio-refining and petroleum refining operations should be integrated to enhance the sustainability of both bio-refining and conventional refining.
