Systems and methods for determining a boiling point distribution of a sample include controlling the rates of temperature increase for a column and an injection port. An analyzer includes a column having a column heating element and an injection port having an injection port heating element. The temperature of the column can be increased at a first rate, and a temperature of the injection port can be increased at a second rate. The first and second rates are selected such that the temperature of the injection port is within about five to fifteen degrees Celsius of the temperature of the column when the temperature of the injection port reaches a target temperature of minimal thermal decomposition.

High temperature simulated distillation

A method for predicting petroleum expulsion. A chemical structure of a kerogen is defined and a plurality of reaction products of the kerogen under geologic heating rates are identified. The plurality of reaction products are grouped into a plurality of product lumps based on their chemical composition and predicting petroleum expulsion for each of the plurality of product lumps based on secondary cracking reactions.

Method for predicting composition of petroleum

A process and apparatus for cracking a hydrocarbon feed containing resid, comprising: heating a hydrocarbon feedstock containing resid; passing said heated hydrocarbon feedstock to a vapor/liquid separator; flashing said heated hydrocarbon feedstock in said vapor/liquid separator to form a vapor phase and a liquid phase containing said resid; passing at least a portion of said resid-containing liquid phase from said vapor/liquid separator to a thermal conversion reactor operating at 649&#xb0; C. or more, wherein the thermal conversion reactor contains coke particles; and converting at least a portion of said resid into olefins.

Integrated vacuum resid to chemicals conversion process

A method for the determination of the aromatic cores or building blocks of a vacuum resid by controlled fragmentation. Molecules can be generated from these building blocks.

Determination of cores or building blocks and reconstruction of parent molecules in heavy petroleums and other hydrocarbon resources

Hydrocarbon feedstreams are desulfurized using an alkali metal reagent, optionally in the presence of hydrogen. Improved control over reaction conditions can be achieved in part by controlling the particle size of the alkali metal salt and by using multiple desulfurization reactors. The processes herein allow a simple and effective method for removing the majority of coke formed in the alkali metal reagent reactions with the hydrocarbon feedstreams. This makes it cost effective to run such processes at higher severities (which result in higher coke production) thereby resulting in increased amounts of valuable converted hydrocarbon product yields. The process improvements herein may also be used to increase total throughput through a unit due to the ability to effectively manage higher coke content in the reaction products.

Alkali metal hydroprocessing of heavy oils with enhanced removal of coke products

Self-compatible heavy oil streams are produced from converted and/or desulfurized fractions. In a preferred embodiment, an incompatibility stream is added to the converted and/or desulfurized stream to reduce the solubility number of the stream. After using a water wash to remove incompatible material, a lighter fraction is removed from the stream to increase the solubility number.

Process for producing a high stability desulfurized heavy oils stream

A method for predicting petroleum production is provided. An exemplary embodiment of The computer-implemented comprises computing a first approximation of an amount of generated petroleum that is retained with a complex organic product using a Threshold and a Maximum Retention value. The exemplary method also comprises revising the first approximation by approximating a process of chemical fractionation using at least one partition factor to create a revised approximation and predicting petroleum production based on the revised approximation.

Method for predicting petroleum expulsion

The electrodesulfurization of heavy oils wherein a feedstream comprised of bitumen or heavy oil is conducted, along with an effective amount of hydrogen, to an electrochemical cell. A current is applied to the cell wherein sulfur from the feedstream combines with hydrogen to form hydrogen sulfide which is removed.

Electrodesulfurization of heavy oils

A method of predicting the composition of hydrocarbon products of a complex carbonaceous material when exposed to specific time and temperature conditions is disclosed. In one embodiment, the material is characterized to obtain elemental, chemical and structural parameters. A representative chemical structure of the material is constructed based on the characterization information. The representative chemical structure is then stochastically expanded to a molecular ensemble chemical structural model that includes heteroatoms. The chemical structural model is coupled to a compositional yield model and the composition of the material products is determined using kinetic modeling. Methods are provided of constructing a chemical structural model of complex carbonaceous material, of coupling a molecular ensemble of chemical structures to a thermal chemical mechanism, of updating an ensemble of chemical structures during the kinetic modeling to reflect chemical reaction products and of eliminating molecules from the system.
