The conversion of canola oil to hydrocarbons using a shape selective zeolite catalyst is reported in this work. Canola oil was passed over HZSM‐5 catalyst in a fixed bed micro‐reactor and the effects of reaction temperature and oil space velocity on the conversion and selectivity were studied using a statistical experimental design. The results show that 60–95 wt% of the canola oil can be converted to hydrocarbons in the gasoline boiling range, light gases and water. The gasoline fraction contained 60–70 wt% of aromatic hydrocarbons and the gases were mostly C3 and C4 paraffins. Furthermore, the spent catalyst could be regenerated completely at 600°C in 1 h with dry air.

Ca lola oil and steam were co‐fed continuously to a 15.5 mm i.d. fixed‐bed reactor loaded with HZSM‐5 catalyst at varying process conditions. The liquid hydrocarbon product contained 60–70 wt% aromatics. The gas product was highly olefinic, while for canola oil alone it was mostly paraffinic. The C2‐C5 olefin selectivity increased with an increase in the steam/canola oil ratio in the feed. In addition, co‐feeding with steam resulted in a two‐fold increase in the catalyst life. Though the exact role of steam in altering the chemistry of the reaction is not known, it is probable that the rates of olefin formation and aromatization reactions are affected by the presence of steam. The product pattern suggests the possibility of propene being the initial olefin in the reaction scheme.

Dried and green aspen poplar wood suspended in water containing alkaline catalysts has been converted completely to an oil, water‐soluble chemicals and gases if heated for one hour in the presence of carbon monoxide in a rocking batch reactor. Within the ranges of parameters studied: temperature (593—633 K), nominal reaction times (0—1 h), water‐to‐wood ratio (0.5:1—5:1), catalyst (Na2CO3, K2CO3, NaOH), amount of catalyst (7.0—12.5 wt %) and initial hydrogen to carbon monoxide ratios (2:1—0:1), the water‐to‐wood ratio was most important. Oil yields of ˜50% with a carbon plus hydrogen content of ˜80% and representing a carbon recovery of ˜66% were obtained. The higher heats of combustion ranged from 32.2 to 36.0 MJ/kg.

. Can. J. Chem. 59,2191Chem. 59, (1981. Some observations are made on the nature of the reactions involved in the conversion of aspen poplar into a variety of chemical products as a result of its interaction with carbon monoxide and water in the presence of sodium carbonate at elevated temperatures and pressures. The original carbon content of the wood is distributed between an oil phase, a complex mixture of highly oxygenated water-soluble products many of which have been identified as low molecular weight aliphatic alcohols, ketones, and acids, and a gaseous phase consisting of mainly hydrogen and carbon dioxide. Using model substances (cellulose, cellobiose, D-glIIcoSe, D-fructose, D-xylose, D-sorbitol, glycerol, and an isolated lignin) information was obtained on the origin of the oil and of the water-soluble products. Studies at temperatures from 160' to 360°C revealed a marked exothermic reaction occurring in the 200-240°C range for wood and cellulose and which was reflected in the nature of the resultingproduct. With increasing temperature there is an increase in the yields of the water-soluble derivatives and also a change in their relative abundance. revCIC que, dans le cas du bois et de la cellulose, il se produit une reaction fortement exothermique dans I'intervalle de 200-240°C et que cette reaction s e reflkte dans la nature des produits obtenus. Une augmentation de la temperature provoque une augmentation des rendements en derives solubles dans I'eau ainsi qu'une evolution dans leur abondance.[Traduit par le journal]

Thermally fractionated components of an oil prepared by the liquefaction of aspen poplar wood have been upgraded using a HZSM-5 zeolite catalyst to yield products rich in benzene, toluene, xylenes and higher molecular weight aromatics. The effect of reactor temperatures on the relative abundance of these products has been studied.On a procCdi a la valorsiation de composCs obtenus par fractionnement thermique d'une huile produite par liquefaction du bois de peuplier faux-tremble, en employant pour catalyseur la ziolithe HZSM-5; on a obtenu des produits riches en benzene, toldne, xylenes et des produits aromatiques de poids molCculaire plus ClevC.
