Case Study

Aquathermolysis of Heavy Crude Oil with Ferric Oleate Catalyst

Li, Yun-Rui, et al. Petroleum Science, 2018, 15, 613-624.

Ferric oleate is an effective catalyst for the hydropyrolysis reaction of heavy oil. Compared with cobalt oleate and nickel oleate, iron oleate is more effective in cracking heavy oil and has better viscosity reduction effect on heavy oil, with a viscosity reduction rate of up to 86.1%. Research has found that iron oleate can significantly increase the content of light components and reduce the contents of resin, N, and S.
Aquathermolysis reaction of heavy crude oil
· First, ferric oleate is prepared by reacting iron (III) nitrate nonahydrate and oleic acid at a molar ratio of 1:1.8 with heating and stirring at 120°C.
· The heavy crude oil underwent aquathermolysis at 200 °C for 24 hours. Initially, 50 g of the heavy crude oil was combined with varying amounts of the ferric oleate catalyst in an autoclave. The mixture was heated to 200 °C and maintained at that temperature for 24 hours.
· The catalyst used in the reaction was devoid of water, while the heavy crude oil contained only 12.0 wt% water. Following the completion of the aquathermolysis reaction, the viscosity of the oil samples was determined at 50 °C using a viscometer. Each oil sample underwent the aquathermolysis process five times.

Effects of SPIONs Prepared from Iron Oleate Precursor on Signaling Pathways

Jens Rauch, et al. Scientific Reports, 2012, 2, 868.

Monodisperse superparamagnetic iron oxide nanoparticles (SPIONs) of various sizes (9 nm and 15 nm) were prepared by thermal decomposition treatment in high-boiling solvents using iron oleate as a precursor. These SPIONs were further surface-coated modified through ligand exchange in DMSO, which can have different effects on signal transduction pathways.
Synthesis of coated SPIONs from iron oleate
· Different sizes of ultra-uniform SPIONs were synthesized through the thermal decomposition of iron-oleate. To produce 9 nm particles, a mixture of 10.8 g of iron chloride and 36.5 g of sodium oleate in a solvent mixture of 80 ml ethanol, 60 ml distilled water, and 140 ml hexane was heated at 70 °C for four hours.
· The resulting iron-oleate complex was separated, washed with distilled water, and evaporated to form a waxy solid. This complex, along with oleic acid, was dissolved in 1-octadecene and heated to 320 °C for 30 minutes. The solution turned turbid and brownish black, indicating the formation of nanocrystals. After cooling, ethanol was added to precipitate the nanocrystals, which were then separated by centrifugation.
· Subsequently, hydrophobic nanoparticles were coated with plain, carboxylated dextran, or dextran with amine end groups using a ligand exchange method.

Study on the stability of ferric oleate on the surface of iron oxide minerals

Joseph-Soly, Sophia, Keith Quast, and Jason N. Connor. Minerals Engineering 83 (2015): 97-104.

The effects of changing the electrochemical potential of the solution as well as changing the pH on the flotation kinetics and recovery of three iron oxide minerals using sodium oleate were examined. The results of this study confirm the importance of ferric oleate stability on the surface of iron oxide minerals as an important requirement for their flotation. The iron oxide minerals used were hematite, magnetite and goethite. The flotation kinetics can be easily simulated using a first order model, which allows prediction of the first order rate constants and final recoveries. The values of these parameters are consistent with the stability region of iron oleate on the Eh vs pH equilibrium diagram of aqueous iron oleate. It is speculated that the flotation of iron oxides in the acidic pH range is promoted by the adsorption of insoluble or colloidal oleate species.
The flotation experiments were conducted using a 300 mL M.C. cell. The cell was made of glass and aeration was provided throughout the bottom by passing air or nitrogen through the frit. Agitation was provided by a small 2-blade impeller driven by an overhead motor at 250 rpm. When the reducing agent (sodium dithionite) was used, a controlled nitrogen flow was fed to the bottom of the cell at a rate of 4 L/min. When nitrogen was used, a purge time of 5 minutes was used to remove air from the slurry in the cell. The amount of ore used for the flotation experiments was always 3 grams. The samples had previously been wet screened between 38 and 75 lm and dried. The amount of water (1 mM sodium nitrate solution) used for each flotation experiment was approximately 1 L. 300 mL of sodium nitrate solution (1 mM) was used in the cell and the water level was maintained by adding water throughout the experiment. The ore was conditioned in water for 2 minutes and then in the presence of the collector for an additional 5 minutes. The collector concentration was nominally 10M (0.3 g/L or 3 kg/t based on the amount of solids present).

Effect of ferric oleate on the properties of synthesized nanoparticles

Ozel, Fatmahan, et al. Journal of Materials Science: Materials in Electronics 24 (2013): 3073-3080.

The effects of different amounts of ferric oleate precursors and different amounts of oleic acid on the properties of nanoparticles synthesized by thermal decomposition were studied. Thermal analysis of ferric oleate precursors by thermogravimetric analysis (TGA) showed that different amounts of oleic acid had an effect on the thermal properties of ferric oleate complexes. During the synthesis of nanoparticles, ferric oleate complexes were continuously refluxed in 1-hexadecane under air atmosphere for 3 h to form nanoparticles. Fourier transform infrared spectroscopy measurements and TGA analysis showed that the nanoparticles were coated with oleic acid. From the X-ray diffraction patterns, all samples were iron oxide nanocrystals, and their crystal size increased from 6.4 nm to 9.8 nm with the decrease of oleic acid.
The ferric oleate precursors were added to 10 ml of 1-hexadecane, respectively, and each solution was heated to reflux and then kept at this temperature for 3 h. The color of the solution was observed to become black. The solution was subsequently cooled to room temperature. The nanoparticles were then precipitated with 40 ml of acetone and 10 ml of hexane to complete the synthesis process of the nanoparticles, and finally they were dispersed in chloroform. The samples were characterized by Fourier transform infrared spectroscopy. For the iron oleate sample, the solid sample was prepared by granulation with KBr powder, while for the FTIR study of the nanoparticles, the nanoparticles dispersed in chloroform solution were first dropped on a KBr disk, and then the chloroform was evaporated in air to finally obtain the product.
