Abstract
processo de fabricação de materiais porosos usando resíduos da indústria têxtil como matéria prima. os resíduos têxteis representam grande parte da quantidade mundial de resíduos sólidos gerados. uma alternativa para o reaproveitamento de tecidos contendo poliéster é a reciclagem química via despolimerização. assim, neste invento, é apresentado um processo para a reciclagem dos resíduos têxteis que contenham poliéster usando este como matéria-prima para fabricação de materiais porosos, como os materiais metalorgânicos (mof´s). o processo envolve a despolimerização do poliéster (i), precipitação (ii), separação (iii), secagem, dissolução (iv), adição de elementos químicos (v) como metais para fabricar mofs, cristalização (vi) e novamente separação e secagem (vii). desta forma, são obtidos produtos como as mofs úteis em diversos setores industriais como petroquímico, tratamento de água e efluentes, alimentos, sucroenergético, químico, produtos de limpeza e curtimento de couro.process of manufacturing porous materials using waste from the textile industry as raw material. Textile waste represents a large part of the global amount of solid waste generated. An alternative for reusing fabrics containing polyester is chemical recycling via depolymerization. Thus, in this invention, a process is presented for recycling textile waste containing polyester using it as raw material for manufacturing porous materials, such as metal-organic materials (mof). the process involves depolymerization of polyester (i), precipitation (ii), separation (iii), drying, dissolution (iv), addition of chemical elements (v) such as metals to make mofs, crystallization (vi) and again separation and drying (viii). In this way, products such as mofs are obtained that are useful in various industrial sectors such as petrochemicals, water and effluent treatment, food, sugar-energy, chemicals, cleaning products and leather tanning.
