    A method of particulate-carbon recovery from the product gas in a coal gasification process of the type using water-carbon slurry combusted with oxygen in a reactor uses water scrubbing for the product gas to obtain particulate carbon together with ash. Certain ash content is trapped in carbon particles which have a tendency of lumping together. The carbon and ash fraction is treated with liquid hydrocarbon for carbon particle wetting and facilitating separation of ash. The recovered carbon is ground to break down bigger carbon particles and sent through a wet-particle separator; carbon particles which pass a predetermined mesh size, e.g., approximately 63 micron mesh, are sent back to the reactor for mixing with the water-carbon slurry inlet for further combustion. The bigger fractions of carbon are either ground down to size again, or diverted for other uses. Recycling carbon particles which pass a 63 micron mesh and are almost devoid of ash improves the carbon utilization and significantly reduces total ash formed. The abrasion damage on components because of ash is also reduced.

    (54) METHOD FOR EXTRACTING AN ACCELERATED ANGLE
    I
    This invention relates to the extraction of a coalescing material from synthesis gas.
    A method is known for extracting a carbonaceous material from synthesis gas, j of which is that the synthesis gas is subjected to washing with water, the resulting suspension of carbon-containing material is mixed with the liquid light hydrocarbon, the mixture obtained at JQ is removed and the suspension is obtained the carbon-containing material in the light hydrocarbon is mixed with heavy oil, followed by the distillation of the light hydrocarbon 1.la
    The disadvantage of the known method is that the recoverable umber-containing material contains another 38: 40% ash and, therefore, the quality of the carbon-containing material is not insensitive.
    The aim of the invention is to improve the quality of the carbon-containing material.
    The goal is achieved by the fact that according to the method for extracting carbon-carbon-25 MATERIAL FROM SYNTHESIS GAS
    burning material from synthesis gas by flushing the gas with water and to obtain an aqueous suspension of carbon-containing material, the resulting aqueous suspension is skip-. Cabin through a sieve of O, O5-O size, 1 mm or after preliminary thickening by sedimentation and mixing with a liquid hydrocarbon through a sieve of 0.5-5 mm in size.
    In case of using a sieve of the size O, b5-0,1. mm as a screening get carbon-containing material, which contains only 10-13% ash.
    If the classification is carried out after. pre-thickening the aqueous suspension and mixing it with liquids, such a hydrocarbon, using a sieve of about 5-5 mm in size, it is possible to further reduce the ash content in the screening to 5-8%. A further decrease in the eolol content in the screening of about 1-2% can be achieved by grinding a condensed mass of 0-100 microns. The thickening of the aqueous suspension is carried out to 2OO-500 g / l, and the liquid carbon dioxide is used in an amount of 5-20% by weight of solids of the condensed mass. If the classification is carried out using a sieve of cell size O 03 mm (in the case of a middle classification of the military suspension) or using a sieve cell having a size of 0.3 mm (in the case of classification after pre-concentration and mixed with liquid hydrocarbon) which contains yoshche 30-35% ash. The flushing of the synthesis gas is carried out in a known manner, i. at 50-3 5 and pressure 5-1OO bar. O-5O% of carbon-containing material carried with synthesis gas in the amount of 3090 g / mg consists of ash. Elimination, i.e. The recovered carbon-containing material can be recycled to the stage of synthesis gas production or, after extreme dehydration, mixing with the separating agent, and used as quality gasification. 1. 1OOOO m / chsii wiPri e f) gas containing 30% kg of carbonaceous carbonaceous material, 5O% of which consists of ash, is subjected to washing with 4O MV4 water at 5 ° С and 5 bar pressure. Receive; aqueous suspension, which contains all the amount of carbon-containing material. This suspension is classified using a 0.1 mm sieve. At the same time, as carbon screening material is obtained, which contains 12% ash. EXAMPLE 2 Example 1 is repeated with the difference that a sieve with a mesh size of 0.05 mm is used. At the same time, as a displacement with liquid carbon,
    screenings get carbon-containing material through a sieve with a size of 0.5-5 mm. rtal, which contains 10% ash. Sources of information.
