Oil shales are broadly dermed as petroleum source rocks containing sufficiently high contents of organic matter (above ca wt. %) to make utilisation a possibility. Like coal, the world's reserves of oil shales are vast being many times larger than. The combustion of a bed of particles impregnated with carbon is considered.

An analysis is developed for the combustion wave after it has progressed some distance into the bed. It is shown that the calculations are considerably simplified by choosing a coordinate system that moves with the combustion wave and by neglecting dispersion of heat or Cited by: 1.

Abstract A simplified mathematical model is developed to determine the amount of oil that survives passage to a hot fracture boundary in an underground retorting process in oil shale. Combustion at or near a fractured surface, heat conduction, oxygeAuthor: R.K. Prasad, G.W. Thomas. The combustion of mixtures of oil shale retorting solid waste and cornstalk particles in a circulating fluidized bed under different conditions was analyzed while investigating the effects of combustion chamber temperature distribution on slag and fly ash.

The concentrations of O2, CO, and NOx in the flue gas at different locations within the combustion unit were also by: 8. processing oil shale to produce shale oil. Oil shale retorting is a very simple process since it basically involves only the application of heat to break down the kerogen followed by removal and quenching of the volatile products.

Oil shale retorts can be grouped into two broad categories: surface processing and in situ processing. In surface processing, the oil shale retorting plants File Size: KB. The spontaneous ignition temperature of the raw oil shale should be below the oil retorting temperature in countercurrent combustion.

This will result in the oxidation zone moving ahead of the retorting zone. In the cocurrent combustion process char remaining after retorting is burned to sustain the by: 9.

Fig. 1 gives a general flow diagram of the oil shale retorting process. Oil shale is a complex mixture of kerogen, minerals and water. The kerogen, the organic fraction present as a complex combination of carbon, hydrogen, sulfur and oxygen, cannot be extracted with ordinary solvents due to its macromolecular by: Utilization of Oil Shale Reverse combustion oil-shale retorting book Gas Table 1.

In most cases, the author’s experience has included the design, construction and operation of facilities to use CMM with the listed technologies. Only in the case of the last three options (propane substitution, CNG production and LNG production) has the experience been limited to.

The experiment was carried out using TG-FTIR to research the combustion mechanism, under different heating rate (10, 20, 40 and 80 °C/min) and simulation of air condition (80% nitrogen: 20% oxygen). The oil shale semi-coke was blended with furfural residue in proportions from 20% to %.Cited by: 9.

An oil shale process is provided to retort oil shale and purify oil shale retort water. In the process, raw oil shale is retorted in an in situ underground retort or in an above ground retort to liberate shale oil, light hydrocarbon gases and oil shale retort water.

The retort water is separated from the shale oil and gases in a sump or in a fractionator or quench tower followed by an API oil Cited by:   Oil shale retorting is a thermochemical process of in situ conversion of oil shale to gaseous and liquid products.

Underground oil shale gasification relies on a number of processes that occur when an oxygen-containing injection agent is injected, with a high-temperature environment in the seam being maintained predominantly by exothermic reactions. The gas combustion retort process (also referred as gas-combustion retorting process) was an above-ground retorting technology for shale oil extraction.

It was a predecessor of the Paraho and Petrosix processes, and modern directly heated oil shale retorting technologies Feedstock: oil shale. Retorting is a frequently used method for producing shale oil from oil shale.

During retorting, heat is usually supplied to the retort by heat-carrier gas of high temperature, such as °C, until retorting ends. In this work, a low-energy-input retorting process using low-temperature carrier gas but without marked loss in oil yield was achieved by a self-heating effect, that is Cited by:   The devolatilization of solid fuels will cause remarkable changes to the pore structures of the resulting char particles, which has a significant influence on successive reactions, such as the combustion of the char particles and the formation of ash.

In the present work, the pore structures of shale chars prepared under different retorting conditions were Cited by: Oil shale samples from Sultani oil shale mine, south of Jordan, were pyrolyzed by a partial combustion to generate shale oil. The produced water was sent for analysis.

The different samples were analyzed for carbon content, and results showed that the TOC was mg per liter of retorted water. Phenol and arsenic contents were measured and found to be 64 mg and Cited by: 1.

The rich oil shale deposits on the W. slope of the Rocky Mt. consitute a potential source of fuel several times as great as the identified reserves of U.S. oil, and processes for extracting synthetic crude oil from the thick seams of brown-black rock have been ready to go for 15 yr.

Technologically, the production of synthetic crude oil from shale is a simple process. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

F Retorting Technologies for Oil Shale HOT GAS RETORTING PROCESSES In the Paraho internal combustion retort a moving bed of shale travels downward and is heated by hot gas flowing upward through it. The oil shale descends the retort as a moving bed. The oil shale is heated by the rising combustion gases from the lower part of the retort and the kerogen in the shale decomposes at about °C ( °F) to oil vapour, shale oil gas and spent shale.

Heat for pyrolysis comes from the combustion of char in the spent ock: oil shale. @article{osti_, title = {Oil shale combustor model developed by Greek researchers}, author = {Not Available}, abstractNote = {Work carried out in the Department of Chemical Engineering at the University of Thessaloniki, Thessaloniki, Greece has resulted in a model for the combustion of retorted oil shale in a fluidized bed combustor.

Since the oil shale retorting process works as a % self-compensation energy technology (heat and gas derived from retorting of oil shale are reused within the on-going and next retorting), the. Additional Physical Format: Online version: Katell, Sidney.

Economic analysis of oil shale operations featuring gas combustion retorting. [Washington]: U.S. Dept. of the Interior, A Model for the Combustion Retorting of Shale-Oil In the combustion retorting of oil shale, a combustion wave is caused to move down through a bed of raw shale particles.

The size of the oil yield from the process depends on keeping the combustion zone separated from the retorting zone and on minimizing the combustion of oil by oxygen.

Oil-shale extraction can damage the biological and recreational value of land and the ecosystem in the mining area. Combustion and thermal processing generate waste material. In addition, the atmospheric emissions from oil shale processing and combustion include carbon dioxide, a greenhouse ock: Oil shale.

As oil shale retorting process is complicated thermochemical conversion modeling of the oil shale retorting process. a FORTRAN subroutine is necessary in the model to simulated the. Kerogen in oil shale in the retorting zone is decomposed to produce gaseous and liquid products including shale oil, and shale oil is withdrawn from the fragmented mass.

The rate of shale oil more» production in the retort depends upon the kerogen content of such a layer in such a fragmented mass through which the retorting zone advances.

Oil shale can be used in various w16,17,18,19,20, from electrical energy via direct combustion to a wide range of petrochemical products (including shale oil and other liquid fuels) via the pyrolysis of kerogen.

Two primary types of processes for oil shale retorting have been developed: ex situ and in situ by: Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons can be produced, called shale oil (not to be confused with tight oil—crude oil occurring naturally in shales).

Shale oil is a substitute for conventional crude oil; however, extracting shale oil from oil shale is more costly than the Primary: Kerogen, Quartz, Feldspar. The influence of the retorting process on the properties of the resulting oil shale is discussed, as are standardized techniques for determining these properties.
