“…40%, it is also possible that an H 2 molecule is generated in-situ by the catalytic reforming of glycerol. Masuda's group has conducted a series of works on glycerol conversion into useful chemicals containing allyl alcohol and propylene [152,[160][161][162].…”

Applications of renewable biomass provide facile routes to alleviate the shortage of fossil fuels as well as to reduce the emission of CO 2. Glycerol, which is currently produced as a waste in the biodiesel production, is one of the most attractive biomass resources. In the past decade, the conversion of glycerol into useful chemicals has attracted much attention, and glycerol is mainly converted by steam reforming, hydrogenolysis, oxidation, dehydration, esterification, carboxylation, acetalization, and chlorination. In this review, we focused on the catalytic hydrogenolysis of glycerol into C3 chemicals, which contain many industrially important products such as 1,2-propanediol, 1,3-propanediol, allyl alcohol, 1-propanol and propylene. In the hydrogenolysis of glycerol into propanediols, advantages and disadvantages of liquid-and vapor-phase reactions are compared. In addition, recent studies on catalysts, reaction conditions, and proposed pathways are primarily summarized and discussed. Furthermore, new research trends are introduced in connection with the hydrogenolysis of glycerol into allyl alcohol, propanols and propylene.

“…The molecular weight distributions of the bitumen and oil product from HPLC were converted into carbon number distributions by assuming the unit structure of heavy oil as _ CH2 _ . The product yield was divided into three groups according to the carbon number: gas oil (Gas Oil, carbon numbers 14-20), vacuum gas oil (VGO, [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] and vacuum residual oil (VR, 41). Carbonaceous solid deposited on the reactor wall was designated as residue, and coke deposited on the surface of the catalyst was analyzed with an elemental analyzer.…”

Our recent studies of the application of iron-based oxide catalysts to upgrading of heavy oils under sub-/supercritical water conditions are reviewed. The effect of reaction parameters on the product yields were investigated for the reaction of bitumen over iron-based oxide catalyst. Reaction pressure greatly affected the product yield, indicating that formation of carbonaceous solid product, called coke, decreased with increase in pressure, and the yield of lighter component (Gas Oil and VGO) was the highest under sub-critical water conditions using both batch and flow type reactors. Kinetic analysis and reaction paths for the decomposition of bitumen were investigated. The decomposition reaction of VR (vacuum residual oil) in bitumen was assumed as second order kinetics, and the activation energy was calculated as 132 kJ/mol. Reaction kinetics were analyzed in details using the Lumping Model. The assigned reaction rate constant for each lump revealed that VR was consecutively converted into VGO, Gas Oil, and Gas, and coke formation was suppressed under sub-critical water conditions, as compared with the main reaction path. Therefore, the reaction process using iron-based oxide catalyst can be applied for the on-site upgrading of heavy oil including bitumen derived from the SAGD (Steam Assisted Gravity Drainage) method, in which bitumen is mined with water under high temperature and pressure.

“…On the basis of the development of catalysts composed of ceria (CeO 2 ), zirconia (ZrO 2 ), and alumina (Al 2 O 3 ) supported on iron oxides (CeO 2 –ZrO 2 –Al 2 O 3 –FeO x , herein referred to as the FeO x -based catalyst), our group previously obtained good results of creating lighter fuel from atmospheric residual oil (AR) by catalytic decomposition under a steam atmosphere and subcritical conditions. ,,− Such iron oxide-based catalysts have also been used to decompose glycerol, − Theobroma cacao husk, pyroligneous acid, lignin, − and ethanol fermentation waste into valuable substances. As stated above, water is required during the post-mining treatment of heavy oil to improve its flow properties, and the addition of water is also an effective means of upgrading this same oil.…”

The behavior of a CeO 2 −ZrO 2 −Al 2 O 3 −FeO x catalyst typically employed during heavy oil decomposition was investigated in conjunction with the addition of H 2 O, as a means of improving the upgrading activity and suppressing coke formation on the catalyst. The upgrading of oil sand bitumen diluted with benzene was examined with this catalyst at various F H 2 O /F bitumen ratios [where F H 2 O is the water flow rate (g h −1 ) and F bitumen is the bitumen feedstock flow rate (g h −1 )] in a fixedbed flow-type reactor. Under optimal conditions (F H 2 O /F bitumen equal to approximately 20) and at a reaction temperature of 693 K, effective catalytic decomposition of the bitumen was observed with the lighter component (gas oil and vacuum gas oil) yield reaching 71 mol % C. In addition, the formation of coke on the catalyst was decreased to less than 14 mol % C. Analyses using quadrupole mass spectrometry determined that this catalyst upgrades the heavy oil through oxidation reactions, in which the lattice oxygen of the iron oxide is consumed and, subsequently, regenerated by the decomposition of water molecules over the catalyst.
