iii Composition analysis for specific phases revealed that mineral matter is easily and. Selective Rejection of Inorganic Fine Solids, Heavy Metals, and Sulfur from Heavy Oils/Bitumen Using Alkane Solvents Article in Industrial & Engineering Chemistry Research 43(22) October   The selective adsorption performances of NFL-S and NFL were evaluated for different concentrations of heavy metal ions at room temperature (V: m = mL g −1, contact exposure time of 10 h).The distribution coefficient of k d is a constant that reflects the affinities of NFL-S and NFL for metal ions.

At first, the adsorption experiments were performed with five divalent metal Cited by: 3. Demetallization of Heavy Oils of High Metal Content through Pyrolysis under Supercritical Water Environment.

Dissolution Methods for the Quantification of Metals in Oil Sands by: Aerated bitumen floats upwards in this vessel, to be collected as a froth that is rich in bitumen but still contains significant amounts of water and mineral solids (Ng et al., a(Ng et al.

An effective oxidant can convert sulfur-containing compounds to much more polar oxidized species. Such oxidants include peroxy organic acids, catalyzed hydroperoxides, inorganic oxidants such as inorganic peroxy acids, peroxy salts and O 3, oxidants can donate oxygen atoms to the sulfur in mercaptans (thiols), sulfides, disulfides and thiophenes.

It is expected to show high affinity not only for phosphates(V) HPO 4 2- arsenate(V) HAsO 4 2-and chromate(VI) CrO 4 2-ions but also oxalates ox 2- perchlorates ClO 4- tartaric acid as well as simultaneous and selective removal of heavy metal and chromate ions (contrary to other ion exchangers) (Saygi et al.

Existing purification methods often cannot address this problem quickly and economically. Here we report a cheap, water stable metal–organic framework/polymer composite, Fe-BTC/PDA, that exhibits rapid, selective removal of large quantities of heavy.

Systems and methods are provided for determining the organic silicon content of petroleum fractions, such as refinery fractions. This can be achieved in part based on performing solvent-enhanced selective filtration on a hydrocarbonaceous sample to substantially remove inorganic silicon from the sample while retaining at least a substantial portion of the organic.

Coarse heavy solids are first removed from the raw crude by passing through a screen of suitable dimensions. The screening device would be arranged as a duplex system, one screen on-stream alternatively while the other is by passed and cleaned.

This step removes large solids like rocks and other larger organic and inorganic solids. A bitumen and heavy oil upgrading process and system is disclosed for the synthesis of hydrocarbons, an example of which is synthetic crude oil (SCO).

The process advantageously avoids the waste attributed to residuum and/or petcoke formation which has a dramatic effect on the yield of hydrocarbon material generated. The process integrates Fischer-Tropsch. Selective Rejection of Inorganic Fine Solids, Heavy Metals, and Sulfur from Heavy Oils/Bitumen Using Alkane Solvents X.-Y.

Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as e is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place.

The economic unattractiveness of heavy crude oils in the global oil market scene is fast changing due to the looming scarcity of light oils. There are huge reserves of heavy oils to which refiners are being reluctantly attracted. The fully developed conventionally available refineries are, however, incapable of processing these heavy crudes without some major.

The removal and recovery of trace-metal compounds in complex matrices, such as heavy crude petroleums and shale oils, is a basic problem in the general area of fundamental petroleum chemistry.

We are developing innovative methods to remove arsenic compounds from shale oil and vanadium and nickel compounds from heavy crude petroleums.

Predict the preferred formation of normal or inverse spinels using arguments from transition metal chemistry (e.g. crystal field stabilization energies). Inorganic solids often have simple crystal structures, and some of these structures are adopted by large families of ionic or covalent compounds.

Because most of the heavy oil, extra-heavy oil, and bitumen are products of the natural biodegradation of crude oil, what remains in the oil sands after their extraction is a highly viscous residuum that, when compared with lighter conventional crudes, is enriched with heavy metals, base metals, sulfur, and nitrogen (Gruson, ; Meyer and.
