specific Embodiment approach

[0051] coal

[0052] In certain embodiments, anthracite or bituminous coal can be comminuted to a size of about 0.841 mm (20 mesh) to about 0.149 mm (100 mesh) and then passed through a 5 Pascal (1atm) ~ about 2.0×10 5 Dissolved and / or extracted, ie liquefied, by immersion in turpentine liquid under pressure in the Pascal (2.0 atm) range. In certain other embodiments, the turpentine liquid may be natural, synthetic or mineral turpentine comprising up to about 50-70% by volume of alpha-terpineol, about 20-40% by volume of beta-terpineol, and About 10% by volume of other components. In certain embodiments, a bed of crushed anthracite or bituminous coal may be stirred through the turpentine liquid at a temperature of 80°C to about 130°C, or possibly up to the boiling point of the turpentine liquid. In certain embodiments, the duration of dissolution and / or extraction, ie, liquefaction, can be from about 10 minutes to about 40 minutes. In certain embodiments, the contact tim...

Embodiment 1

[0104] Example 1. In this example, coal from the Pittsburgh coal seam in Washington County, Pennsylvania was liquefied with the reagent alpha-terpineol. Coal samples were obtained from the Coal Bank of Pennsylvania State University, and the approximate analysis provided by the university is as follows: 2.00 wt.% moisture received, 9.25 wt.% dry ash, 38.63 wt.% dry volatiles and 50.12 wt.% dry fixed carbon. The particle size of the coal sample was about 60 mesh. About 60 grams of alpha-terpineol was gently added to about 30 grams of coal sample placed in the extraction vessel, resulting in a reagent-to-sample ratio of 2:1. The capped but not hermetically sealed extraction vessel containing the resulting mixture of α-terpineol and coal was maintained at a constant temperature of about 96°C with constant agitation. The pressure in the extraction vessel is maintained at slightly below about 1.01 x 10 5 Pascal (1 atm) ambient pressure without boiling α-terpineol. After about 30...

Embodiment 2

[0105] Embodiment 2. This embodiment is almost the same as Embodiment 1, the difference has two aspects. As in Example 1, after maintaining the temperature at about 96°C for about 30 minutes, the extraction vessel containing the coal sample and α-terpineol was held at a temperature of about 135°C for an additional period of about 30 minutes. The pressure in the extraction vessel is maintained at slightly below about 1.01 x 10 5 Pascal (1atm) ambient pressure. The conversion rate of the coal sample, ie the degree of liquefaction, was determined to be about 70 wt.%.

Abstract

A method of extracting hydrocarbon-containing organic matter from a hydrocarbon-containing material includes the steps of providing a first liquid comprising a turpentine liquid; contacting the hydrocarbon-containing material with the turpentine liquid to form an extraction mixture; extracting the hydrocarbon material into the turpentine liquid; and separating the extracted hydrocarbon material from a residual material not extracted.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of U.S. Application Serial No. 12 / 174,139, filed July 16, 2008, and 12 / 053,126, filed March 21, 2008, and claims U.S. Provisional Priority to Patent Application No. 60 / 973,964, each of which is incorporated herein by reference in its entirety. technical field [0003] This invention relates to the field of extraction of hydrocarbons from hydrocarbonaceous feedstocks. Background technique [0004] Fossil fuels in solid, semi-solid, highly viscous or viscous form (hereinafter individually and collectively referred to as fossil fuels), also known as hydrocarbon-containing organic matter, the liquefaction, dissolution and / or extraction of which has proven extremely challenging and is very difficult. As used herein, these fossil fuels include, but are not limited to, coal, oil shale, tar sands, and oil sands (collectively referred to hereafter as tar sands), as well as crude oil,...
