“…A way to upgrade the quality of biomass pyrolysis oil is hydrocracking on the liquid products using catalyst. Noble metal such as platinum (Pt) and palladium (Pd) can be used as catalyst in hydrocracking process [9][10][11][12] . However, the use of noble metals as catalyst is inefficient due to the cost of the noble metals.…”

Cobalt, Molybdenum, Co-Mo and Mo-Co catalysts supported on mesoporous silica-alumina (MSA) were synthesized in this work. The MSA and catalysts were characterized by FTIR spectrometer, AAS, TEM, SAA and acidity test (pyridine adsorption). Their catalytic activity were investigated on hydrocracking of α-cellulose pyrolysis oil. The MSA had BET specific surface area of 52.01 m 2 /g, total pore volume of 0.64 cm 3 /g and pore diameter of 3.80 nm based on BJH desorption method. The results showed that hydrocracking of α-cellulose pyrolysis oil using Co/MSA, Mo/MSA, Co-Mo/MSA and Mo-Co/MSA catalysts was selective for acetic acid, 1-hydroxy-2-propanone and 2-furancarboxyldehide production. The highest amount of liquid product was obtained by using Co-Mo/MSA catalyst (82.13 wt.%).

“…Nevertheless, it is interesting to understand if the methane produced originates from a small contribution of type D cracking or from a hydrogenolytic route catalyzed by the metal sites alone. Rates of formation of methane can be used to assess the extent of the monofunctional hydrogenolysis mechanism, as we have reported before when comparing platinum and palladium on a similar support [32]. Therefore, we investigated the dependence of the methane yield on palladium loading.…”

“…Our previous work compared amorphous silicaalumina (ASA) catalysts loaded with platinum and palladium in the hydrocracking/ hydroisomerization of n-hexadecane at industrially relevant operating conditions. The study pointed out that on Pd/ASA the paraffin reacts according to the classical scheme of successive isomerization steps followed by cracking, while on Pt/ASA a marked contribution of monofunctional, metal-catalyzed hydrogenolysis was observed [32].…”

“…The reactor system, the analysis system and the experimental procedures have been described in detail in a previous publication [32], and are only briefly presented here. The catalysts were tested on the hydroisomerization/ hydrocracking of n-hexadecane (for synthesis, 99%, Merck 820633) performed in a fixed bed tubular reactor, operated in co-current down flow mode.…”

BackgroundSince the 1980s [1,2], colloidal systems such as microemulsions (ME) have been widely investigated, especially for the synthesis of nanomaterials for various applications. In the field of catalysis, nanoparticles of noble metal or metal oxides, responsible for the catalytic activity and selectivity, are usually involved in the composition of the catalytic material [3]. A catalyst normally consists of metal nanoparticles deposited onto a carrier such as silica or alumina. Ideally, the nanoparticles will present a highly active surface area due to high metal dispersion. In addition, the surface structure of the nanoparticles, which depends on their size and shape, are related to the selectivity of the catalysts, for instance this is important in the case of alkane isomerization, which is a structure sensitive reaction [4].Depending of the size, the nanoparticles will contain various defects, which will correspond to catalytic sites with different selectivities and activities. These active sites correspond to groups of metal atoms placed on the edges, corners, and terraces structures at the surfaces of the metal nanoparticles. These metal atoms will have different coordination states and present different electronic effects, which will consequently result in different catalytic activity and selectivity. This is the reason why the preparation of nanoparticles with well-defined particle size is still of great interest in the field of catalysis. If one is able to obtain well-defined metal nanoparticles, it will be possible to relate the selectivity and activity of the reaction to some specific size and consequently to have a better understanding of the catalytic reaction mechanism. Consequently, by using a well-designed nanomaterial as catalyst, it will be possible to predict its properties regarding its catalytic activity and selectivity.During these last years, it has been shown that nanomaterials obtained from ME present specific properties, especially regarding the catalytic selectivity compared to catalysts prepared from traditional methods. Several catalytic processes have been investigated using these types of catalysts, i.e., high temperature catalytic combustion of methane, electro-catalyst for hydrogen production from methanol, production of polyalcohols from synthesis gas, Diesel production from synthesis gas via Fisher-Tropsch and hydrocracking of waxes, etc. [3][4][5][6][7][8][9][10][11]. These very different processes are associated to a great range of catalytic materials. The microemulsion method, based on water-in-oil, oil-in-water and bicontinuous ME, has shown to be suitable for the preparation of all these different types of materials [12][13][14][15][16][17][18][19][20][21][22].Even though a few valuable efforts were previously done to understand the formation of nanomaterials in ME systems [23][24][25], comprehensive research in this area is still needed to clarify this process, in order to reach a better control of nanoparticle characteristics and to understand why the formed nanopartic...
