OBTAINING A SILICA RICH SYNTHETIC OFFERTITIS. APPLICATION TO THE PRODUCTION OF HYDROCARBONS RICH IN LIGHT OLEFINS BY PROCESSING METHANOL AND / OR DIMETHYL ETHER

摘要

THE PRESENT INVENTION CONCERNS OBTAINING STABILIZED, LOW OR HIGHLY SILICA ENRICHED OFFERTIES OF THE MAIN PART OF THE ORIGINAL ALKALI IONS (POTASSIUM IN PARTICULAR) BY PERFORMING CYCLES THERMAL TREATMENTS-EXTRACTIVE TREATMENTS IN THE LIQUID PHASE (CATIONIC EXCHANGES - ACID ATTACKS ) ON SYNTHETIC OFFERINGS COMPRISING POTASSIUM IONS AND TETRAMETHYLAMMONIUM IONS, SILICA ALUMINUM MOLD RATIO BETWEEN 4 AND 10, AND THE USE OF HIGHLY SILICA ENRICHED OFFERINGS FOR CONVERTING METHANOL, OR DIMETHYL ETHER, OR A MIXTURE THEREOF TWO REAGENTS IN LIGHT HYDROCARBONS RICH IN C, C AND C OLEFINS.
