Le procede d'extraction est mis en œuvre en utilisant un agent fluidisant pour fluidiser des particules de sable petrolifere a l'interieur d'une zone de contact dans laquelle l'agent fluidisant entre en contact avec le sable petrolifere et maintient le sable petrolifere dans l'etat fluidise. Au moins une majorite de l'agent fluidisant est dans un etat vapeur ou supercritique a l'interieur de la zone de contact.

Cette composition d'ester comprend le produit de reaction, d'une part, d'un alcool lineaire ou ramifie de formule generale R(OH)n ou R est un groupe aliphatique ou cyclo-aliphatique possedant environ de 2 a 20 atomes de carbone et n est au moins egal a 2, et, d'autre part, d'au moins un acide monocarboxylique ramifie dont le nombre d'atomes de carbone se situe dans une plage allant de C5 a C13. La composition d'ester synthetique contient environ 5 % a 35 % de groupes hydroxyle non convertis en fonction de la quantite totale de groupes hydroxyle dans l'alcool lineaire ou ramifie.

Nuclear magnetic resonance (NMR) was used to study a suite of such guests which were either deuterated or fluorinated, while electron spin resonance (ESR) was used to examine paramagnetic TEMPOL

Nonetheless, agencies, including the EIA, forecast that demand for hydrocarbons will continue to dominate the energy world and by 2050 are expected to supply around 75% of all the BTUs consumed worldwide. Therefore, it is incumbent for scientists and engineers to innovate and provide means to mitigate the environmental impact of the burning of fossil fuels. The use of natural gas to replace coal in power plants is one application already underway. Major opportunities toward sustainability are needed as we continue to use fossil fuels. Data is presented to show that an alkane-based solvent can be used to extract a deasphalted bitumen oil (DBO) from oil sands. This water free process also generates a product stream much lower in metals and asphaltenes, richer in desirable hydrogen content, and with characteristics similar to those of a refinery deasphalted oil (DAO). Based on a suite of analyses, representative structures for propane-extracted DBOs are presented. From this information, it is demonstrated that transportation fuel components can be produced by direct catalytic cracking of the DBOs with the option to pretreat using low-severity hydroprocessing. Thus, in contrast to high-severity processing required to upgrade water-extracted bitumen from oil sands, DBO can be used as a direct feedstock to a variety of relatively low-severity downstream upgrading (refining) units and upgraded to high-quality transportation fuels at substantially reduced greenhouse gas (GHG) emissions levels.

They cleave homolytically at the C-H alkyl bond to produce phenols and they cleave homolytically at the C-H alkyl bond, and rearrange to an aryloxy radical leading to carbonyl compounds and ultimately to other products. Results obtained with the methyl ethers of 1- and 2-naphthol and with anisole show clearly that relative kinetics for these pathways differ for different substrates. Unimolecular decomposition rates at 400C and at 450C show that 1-methoxy naphthalene decomposes faster than 2-methoxy naphthalene which in turn is more thermally reactive than anisole.
