英文摘要	the carbon chain extension and hydrodeoxygenation steps play critical roles in the high-energy-density hydrocarbons production. in this paper, a systematic study had been carried out to investigate one-pot aqueous phase catalytic conversion of sorbitol to gasoline (stg) over bifunctional ni-based catalysts. characterization technologies of n-2 physisorption, x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem) and nh3 temperature-programmed desorption (nh3-tpd) were used to study the textural properties, phase compositions, acid behavior and morphologies of the catalysts. the catalytic performances were tested in a fixed bed reactor. it was found that the physically mixed ni/hzsm-5 and ni/silica-gel (mesoporous sg) catalyst realized the carbon chain extension and exhibited excellent performances on hydrodeoxygenation (hdo) reaction (46.9% of gasoline (c5-c12) yield and 45.5% of c7-c12 hydrocarbons in the gasoline products). especially, the temperature of stg (553-593 k) was lower obviously than that of the traditional methanol to gasoline (mtg) process (623-773 k). it provided a novel transformation of sorbitol to long-chain alkanes by one-pot process over the bifunctional catalyst (ni@hzsm-5/sg), wherein hydrodeoxygenation, ketonization and aldol condensation steps were integrated.
