Resumo: Black liquor formed in the pulping of pulp and paper industry contains pitchs, colloidal resinous materials and wood derivatives that accumulate in machinery of the pulp industry, damaging equipment or the final product. The objective of this work was to study the use of cellulose-based aerogels in pitch removal, a function of talc in most industries. Aerogels are porous solids, produced from lyophilization of a colloidal suspension of nanofibrillated cellulose and xylans, in different proportions, and PAE resin. The pitch counts were made using a Neubauer camera. All the aerogels presented adsorption power, although higher the CNF content, better the adsorbent. In general, 100:0 aerogels (CNF: Xylan) are better adsorbents compared to 30:70 aerogels. No proportionality was observed between mass and adsorption capacity, suggesting the existence of specifics amounts for each aerogel.

O objetivo do trabalho foi estudar o uso de aerogéis à base de celulose na remoção dos pitchs, função exercida pelo talco na maioria das indústrias. Os aerogéis são sólidos porosos, produzidos a partir de liofilização de uma suspensão coloidal de celulose nanofibrilada e xilanas, em diferentes proporções, e resina PAE - poliamina-epiclorohidrina. A contagem dos pitchs foi feita com uma câmara de Neubauer. Todos os aerogéis apresentaram poder de adsorção, de modo que quanto maior o teor de CNF-Celulose Nanofibrilada, melhor o adsorvente. De modo geral, os aerogéis 100:0 (CNF:Xilana) são melhores adsorventes que os aerogéis 30:70. Não foi observada uma proporção entre massa e capacidade de adsorção, sugerindo a existência de quantidades específicas para cada aerogel.Universidade Federal de Viçosa - UFV2017-03-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/kswpshttps://periodicos.ufv.br/jcec/article/view/244694160303201757310.18540/jcecvl3iss3pp573-583The Journal of Engineering and Exact Sciences; Vol. 3 No. 3 (2017); 573-583The Journal of Engineering and Exact Sciences; Vol. 3 Núm. 3 (2017); 573-583The Journal of Engineering and Exact Sciences; v. 3 n. 3 (2017); 573-5832527-1075reponame:Revista de Engenharia Química e Químicainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/2446941603032017573/897Silva, Fernanda SantosRodrigues, Marina Oliveirade Oliveira, Rubens Chavesinfo:eu-repo/semantics/openAccess2020-07-14T22:34:06Zoai:ojs.periodicos.ufv.br:article/2263Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/indexONGhttps://periodicos.ufv.br/jcec/oaijcec.journal@ufv.br||req2@ufv.br2446-94162446-9416opendoar:2020-07-14T22:34:06Revista de Engenharia Química e Química - Universidade Federal de Viçosa (UFV)false
