Download or read book Experimental Study of In situ Upgrading for Heavy Oil Using Hydrogen Donors and Catalyst Under Steam Injection Condition written by Zhiyong Zhang and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research is a study of the in-situ upgrading of Jobo crude oil using steam, tetralin or decalin, and catalyst (Fe(acac)3) at temperatures of 250 °C, 275 °C and 300 °C for 24 hours, 48 hours and 72 hours using an autoclave. Viscosity, API gravity and compositional changes were investigated. We found that tetralin and decalin alone were good solvents for heavy oil recovery. Tetralin or decalin at concentrations of 9% (weight basis) could reduce the Jobo crude oil viscosity measured at 50 °C by 44±2% and 39±3%. Steam alone had some upgrading effects. It could reduce the oil viscosity by 10% after 48 hours of contact at 300°C. Tetralin, decalin or catalyst showed some upgrading effects when used together with steam and caused 5.4±4%, 4±1% and 19±3% viscosity reduction compared with corresponding pre-upgrading mixture after 48 hours of reaction at 300°C. The combination of hydrogen donor tetralin or decalin and catalyst reduced the viscosity of the mixture the most, by 56±1% and 72±1% compared with pre-upgrading mixture. It meant that hydrogen donors and catalyst had strong synergetic effects on heavy oil upgrading. We also found that 300 °C was an effective temperature for heavy oil upgrading with obvious viscosity reduction in the presence of steam, hydrogen donors and catalyst. Reaction can be considered to have reached almost equilibrium condition after 48 hours. The GC-MS analysis of the gas component showed that light hydrocarbon gases and CO2 were generated after reaction. The viscosity reduction from decalin use is larger than that of tetralin because decalin has more hydrogen atoms per molecule than tetralin. A mechanism of transferring H (hydrogen atom) from H2O and hydrogen donors to heavy oil, which can lead to structure and composition changes in heavy oil, is explained. The study has demonstrated that in-situ heavy oil upgrading has great potential applications in heavy and extra heavy oil recovery.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted to investigate the feasibility of in situ upgrading of heavy oil by the use of an orgametallic catalyst and a hydrogen donor (tetralin). The experiments used a vertical injection cell into which a mixture of sand, water, and Jobo oil was thoroughly mixed and packed. Two types of runs were conducted: a run where the tetralin and catalyst were mixed within the mixture before packing into the cell, and the other was conducted by injecting a slug of the tetralin-catalyst solution before commencing with the steam injection. The Jobo oil used had an oil gravity of 12.4° API and a viscosity of 7800 cp at 30°C. The injection cell was placed in a vacuum jacket and set to a reservoir temperature of 50°C. Superheated steam at 273°C was then injected into the injection cell at a rate of 5.5 cc/min (cold water equivalent). The cell outlet pressure was maintained at 500 psig. Produced liquid samples were collected periodically through a series of separators. The produced oil was divided into two halves and several measurements and analyses were carried out on them. These included viscosity, density, elemental analysis and liquid composition. Experimental results indicated that tetralin alone was a worthy additive and increased recovery by 15% compared to that of pure steam. The premixed tetralincatalyst run showed improved recovery to that of pure steam by 20%. Experiments also showed that, when the tetralin-catalyst solution was injected rather than mixed, the results were equivalent to tetralin injection runs. Oil production acceleration was displayed by all the runs with tetralin and tetralin-catalyst but was more pronounced with the availability of catalyst.

Download or read book Enhancement of Heavy Oil bitumen Thermal Recovery Using Nano Metal Particles written by Yousef Hamedi Shokrlu and published by . This book was released on 2014 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclic steam stimulation (CSS) and steam assisted gravity drainage (SAGD) are the most commonly applied techniques used for heavy oil (HO) and bitumen (B) recovery. However, these methods, especially CSS, suffer from low recovery factor and production of highly viscous oil that requires additional up-grading treatment for transportation. The objective of this dissertation is to overcome such problems by application of metal nano-particles as catalysts. During the steam stimulation process, a series of reactions, called aquathermolysis, occur among oil, water and reservoir matrix. These reactions tend to break down the complex and big organosulfur compounds in the asphaltene fraction of the HO/B by cleaving the C-S bonds. Catalyzing these reactions can provide significant upgrading of the oil at the temperature range of steam stimulation. This catalysis can be achieved by using transition metal nano-particles. In this research, nickel, which is commercially used in many catalysis processes in the industry, is used for this purpose. Initially, the interactions of the nickel nano-particles with oil and water at different temperatures are studied, and the effect of the concentration, size and type of the catalyst on the process is evaluated. Next, a methodology is proposed to efficiently stabilize and inject the metal nano-particles into heavy oil reservoirs for catalysis purpose. Also, the degree of catalysis of the aquathermolysis is determined by studying the kinetics of the aquathermolysis and catalytic aquathermolysis of heavy oil. Finally, the effect of this catalysis on the recovery factor of the model cyclic steam stimulation is studied experimentally. In addition to steam injection dominated by aquathermolysis reactions, the influence of the nickel ionic solution on the low temperature oxidation during in-situ combustion is studied through TGA-FTIR and kinetic analysis. It is concluded that the quality of the produced oil can be significantly improved by using the nickel nano-particles during steam stimulation or in-situ combustion. The recovery factor of the above mentioned recovery processes also increases due to decreasing oil viscosity in the reservoir by catalysis. This method can significantly improve the economics of the thermal heavy oil recovery projects and decrease the complexities of heavy oil transportation and ex-situ upgrading.

Download or read book Catalysis and Zeolites written by Jens Weitkamp and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zeolites occur in nature and have been known for almost 250 years as alumino silicate minerals. Examples are clinoptilolite, mordenite, offretite, ferrierite, erionite and chabazite. Today, most of these and many other zeolites are of great interest in heterogeneous catalysis, yet their naturally occurring forms are of limited value as catalysts because nature has not optimized their properties for catalytic applications and the naturally occurring zeolites almost always contain undesired impurity phases. It was only with the advent of synthetic zeolites in the period from about 1948 to 1959 (thanks to the pioneering work of R. M. Barrer and R. M. Milton) that this class of porous materials began to playa role in catalysis. A landmark event was the introduction of synthetic faujasites (zeolite X at first, zeolite Y slightly later) as catalysts in fluid catalytic cracking (FCC) of heavy petroleum distillates in 1962, one of the most important chemical processes with a worldwide capacity of the order of 500 million t/a. Compared to the previously used amorphous silica-alumina catalysts, the zeolites were not only orders of magnitude more active, which enabled drastic process engineering improvements to be made, but they also brought about a significant increase in the yield of the target product, viz. motor gasoline. With the huge FCC capacity worldwide, the added value of this yield enhancement is of the order of 10 billion US $ per year.
