new methods of image enhancement are poor in oil shale by moroccan kerogene mineralurgique for use directly as a fuel or for the preparation of shale oil

摘要

the present invention describes a new process of comprehensive treatment and development of oil shale kerogen (poor, rich in carbonates and clays. these shales are characterized by the close links between the physical - chemical organic (kerogen) mineral and gangue.the objectives of these processes by a wet process to release the kerogen and the separation of mineral phases by acid leaching, followed by chemical reagents used in the flotation of attrition (hydrochloric acid, sulfuric acid or phosphoric acid) and soft cient.oil shale enriched, thus obtained, containing kerogen in the order of 60% to 70%, depending on the nature of the acid used. they can be used directly as a fuel or they may undergo pyrolysis to prepare the oil from the oil shale.from oil shale and kerogen content of the timahdit 17% and 38% of carbonates, 45% of quartz, pyrite, clay and other minerals is oil shale enriched (sbe) of 60% to 70% of kerogen, 0% of carbonates, clays and quartz are the remnants of that were related to the structure of kerogen.the products of these processes are cac12, caso4, ca3 (po4) 2 and the ash of the burning of oil shale enriched.
