description	The present invention relates to a synthetic-silica catalyst used in a heterogeneous catalysis method for the effective conversion of residual glycerin resulting from the production of biodiesel into formic acid with high selectivity and stability, in a continuous-flow reaction. It should be noted that products with high added value are formed with the mere presence of an oxidizing agent, including without a catalyst. In this case, the conversion of the residual glycerin occurs by homogeneous catalysis, by the action of the components left over from the synthesis of the biodiesel, with the formation of major components, such as formic acid, cyclic ethers and diglycerol, in continuous-flow and reflux reactions. The reaction can also be brought about by adding sodium salts to the process of homogeneous catalytic conversion of the commercial glycerin. The process developed in the present invention reuses the residual glycerin without the need for purification before its transformation into products of high added value and renewable origin, enhancing the usefulness and potential of the invention. L'invention concerne l'utilisation d'un catalyseur à base de silice synthétique dans un procédé de catalyse hétérogène pour favoriser la conversion efficace de la glycérine résiduelle, résultant de la production de biodiesel, en acide formique à sélectivité et stabilité élevées dans une réaction à flux continu. Notamment, même en l'absence du catalyseur, seulement en présence d'un agent oxydant, il est possible de vérifier la formation de produits à haute valeur ajoutée. Dans ce cas, la conversion de la glycérine résiduelle se produit par catalyse homogène, par l'action de composants résiduels de la synthèse du biodiesel, avec la formation de composés majoritaires, tels que l'acide formique, les éthers cycliques et le diglycérol, dans des réactions à flux continu ou reflux. La réaction peut également être effectuée par ajout de sels de sodium dans le processus de conversion catalytique homogène de la glycérine commerciale. Le procédé développé dans la présente invention valorise la glycérine résiduelle sans avoir recours à la purification avant sa transformation en produits à haute valeur ajoutée, mais d'origine renouvelable, fournissant plus d'intérêt et de potentiel à l'invention.

Esta invenção utiliza um catalisador à base de sílica sintética, em um método de catálise heterogênea, para promover a efetiva conversão da glicerina residual, resultante da produção de biodiesel, em ácido fórmico com elevada seletividade e estabilidade, em uma reação de fluxo contínuo. Destaca-se que, mesmo na ausência do catalisador, apenas na presença de um agente oxidante, é possível verificar a formação de produtos com alto valor agregado. Nesse caso, a conversão da glicerina residual ocorre por catálise homogênea, pela ação de componentes remanescentes da síntese do biodiesel, com a formação de compostos majoritários, tais como o ácido fórmico, éteres cíclicos e diglicerol, em reações de fluxo contínuo e refluxo. A reação pode também ser realizada pela adição sais de sódio no processo de conversão catalítica homogênea da glicerina comercial. O processo desenvolvido nesta invenção valoriza a glicerina residual, sem a necessidade de purificação antes de sua transformação em produtos de alto valor agregado, mas de origem renovável, agregando mais interesse e potencialidade à invenção.</description><language>eng ; fre ; por</language><subject>ACYCLIC OR CARBOCYCLIC COMPOUNDS ; CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOIDCHEMISTRY ; CHEMISTRY ; METALLURGY ; ORGANIC CHEMISTRY ; PERFORMING OPERATIONS ; PHYSICAL OR CHEMICAL PROCESSES OR APPARATUS IN GENERAL ; THEIR RELEVANT APPARATUS ; TRANSPORTING</subject><creationdate>2022</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20220630&DB=EPODOC&CC=WO&NR=2022133560A1$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25542,76289</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20220630&DB=EPODOC&CC=WO&NR=2022133560A1$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>MOURA BREDER, Samuel</creatorcontrib><creatorcontrib>LARA SANGIORGE, Daniel</creatorcontrib><creatorcontrib>RANGEL BASTOS, Alexander</creatorcontrib><creatorcontrib>DE FIGUEIREDO PORTILHO, Marcio</creatorcontrib><creatorcontrib>DE CASTRO OLIVEIRA, Cíntia</creatorcontrib><creatorcontrib>CHAGAS, Poliane</creatorcontrib><creatorcontrib>PACHELI HEITMANN RODRIGUES, Ana</creatorcontrib><creatorcontrib>ALVES DE OLIVEIRA, Luiz Carlos</creatorcontrib><title>METHOD FOR CATALYTIC CONVERSION OF GLYCERIN INTO PRODUCTS OF HIGH ADDED VALUE, AND USE</title><description>The present invention relates to a synthetic-silica catalyst used in a heterogeneous catalysis method for the effective conversion of residual glycerin resulting from the production of biodiesel into formic acid with high selectivity and stability, in a continuous-flow reaction.
