  has been undertaken with the aim of designing promising noble-metal-free catalysts for efficient hydrodeoxygenation (HDO) of dibenzofuran (DBF) into fuel grade hydrocarbons. For this, various Ni/Al-SBA-15 catalysts with different Si/Al (50, 60, 70 and 80) mole ratios were synthesized and their catalytic performance was tested for HDO of DBF in a batch reactor. The catalysts were systematically characterized

  进行这项工作的目的是设计有前途的无贵金属催化剂，以将二苯并呋喃（DBF）高效加氢脱氧（HDO）转化为燃料级碳氢化合物。为此，合成了具有不同Si / Al（50、60、70和80）摩尔比的各种Ni / Al-SBA-15催化剂，并在间歇反应器中测试了它们的催化性能，以评估DBF的HDO。使用XRD，N 2-吸附-解吸，拉曼，H 2 -TPR，NH 3 -TPD，XRF和FESEM技术对催化剂进行了系统表征。活动结果表明，DBF的HDO通过镍位点上的苯加氢，然后裂解酸性位点上的C-O键，生成不饱和烃。Ni位点上的不饱和烃的进一步氢化得到双环己烷作为主要产物。值得注意的是，除Ni / SBA-15和Ni / Al-SBA-15（80）（Si / Al摩尔比= 80）催化剂外，所有催化剂的DBF转化率均为100％，分别显示97.97％和99.31％ 。在这项研究中注意到的一个重要观察结果是，将Al掺入Ni

  catalytic activity of nickel and cobalt phosphides, with a metal loading of 5 wt.%, supported on silica was investigated in the hydrodeoxygenation reaction (HDO) of dibenzofuran (DBF) as a model oxygenated compound at different contact times, H2 pressures and H2/DBF molar ratios. The aim of the study was to understand the mechanism of the reaction and to study the impact of H2 pressure and H2/DBF molar

• Hydrodesulfurization of dibenzothiophene, 4,6-dimethyldibenzothiophene, and their hydrogenated intermediates over bulk tungsten phosphide

  The kinetics of the hydrodesulfurization (HDS) of dibenzothiophene (DBT), 4,6-dimethyldibenzothiophene (4,6-DMDBT), and their hydrogenated intermediates over bulk tungsten phosphide (WP) was studied. WP possessed high hydrogenation/dehydrogenation activity but was highly sensitive to piperidine inhibition. 4,6-DMDBT reacted faster than DBT, and both DBT and 4,6-DMDBT reacted mainly through the hydrogenation pathway. The methyl groups suppressed the direct desulfurization of 4,6-DMDBT but significantly promoted the hydrogenation of 4,6-DMDBT and the dehydrogenation of 1,2,3,4-tetrahydro-4,6-dimethyldibenzothiophene (TH-4,6-DMDBT) and 1,2,3,4,4a,9b-hexahydro-4,6-dimethyldibenzothiophene, but decreased the rate of hydrogenation of TH-4,6-DMDBT. Piperidine inhibited the HDS of 4,6-DMDBT much more strongly than that of DBT. Substantial dehydrogenation of TH-4,6-DMDBT to 4,6-DMDBT and two of its isomers occurred. The formation of these 4,6-DMDBT isomers in the dehydrogenation of TH-4,6-DMDBT and the hydrocracking of 1-methyl-4-(3-methylcyclohexyl)-benzene, as well as the formation of cyclopentylphenylmethane and (cyclopentylmethyl)cydohexane, is ascribed to the metallic character of WP.
