| titleOfInvention | zeolites synthesized in the total absence of organic director and its synthesis process |
| abstract | SYNTHESIZED ZEOLITES IN THE TOTAL ABSENCE OF ORGANIC DIRECTOR AND THE SUMMARY PROCESS The present invention relates to the synthesis process in the total absence of organic directorate of crystalline aluminosilicates with zeolitic structures and products thereof, in particular with ZSM-5 type MFI structure. Methodologies related to the preparation of these materials are conventionally reported using reagents that provide the required silicon and aluminum oxides in the presence of a directing agent, and in some cases even co-directives, inorganic acids and organic solvents; The present invention relates to a zeolite synthesis process in the total absence of organic director, and the zeolites produced by this process, in particular equivalents to ZSM-5, herein referred to as LCP-5 (Catalysis and Petrochemical Laboratory number 5) when obtained by the new preparation route. In addition to eliminating the use of organic structural drivers, inorganic acids and organic solvents, which are costly, toxic and corrosive materials, the new route also optimizes synthesis time and temperature, according to the "Green Chemistry" precepts, where The principles of chemistry are guided by concern for environmental impact. The process involves hydrogel preparation using vigorous stirring and heat treatment, playing an important role in the final product obtained. This agitation acts by initiating the crystallization process in the absence of an organic director, as it provides the increase of the "creation collision" (productive collision) of the desirable product. |
