| 英文摘要 | direct hdo process for difurfurylidene acetone dimer (f2a) conversion to liquid alkanes (c8 c14) at 260 degrees c in a batch reactor was investigated over different material supported 1 wt%pt catalysts, including sapo-11, hzsm-5, sio2-al2o3, mcm-22, and home-made sio2-zro2. cs-cm alkanes of 55.8% was obtained over the optimized i wt%pt/sio2-zro2 due to its proper pore size of 9.0 nm and moderate acidic centers, together with more than 10% carbon yield of the oxygenated hydrocarbons, including c11-c13 chain alcohols 82 ketones and the hydrogenated f(2)a dimers with furan ring (h-f(2)a dimers). to improve the liquid alkane yield, a two-step process for f(2)a conversion was also investigated, which included low-temperature hydrogenation at 50 c over raney ni catalyst in a batch reactor and the subsequent high-temperature hydrodeoxygenation (hdo) at 280 degrees c over 1 wt%pt/sio2 zro2 in a fixed-bed reactor. the selectivity of 1,5-di(tetrahydro-2-furany1)-3-pentanol (ii-c) was the highest of 83.0% among the hydrogenated intermediates of h-f2a dimers due to the protonation effect of methanol as the solvent and the hydrogenation of c=c bonds by ni active centers. in the same time, the high content of this saturated alcohol h-dimer of ii-c increased the solubility and stability of the intermediates in methanol solvent. high carbon yield of c-8-c-14 alkanes of 82.9%(mol) was obtained after oxygen atom removal from h-f(2)a dimers via, the second-step hdo reaction. long time operation showed the stability of 1 wt%pt/sio2-zro2 as hdo catalyst, deduced from the steady phase structure, acidity of sio2 zro2 support and pt active centers by catalyst characterization.
