Avaliação de materiais adsorventes com diferentes propriedades para a captura d...

Gouveia, Lucas Gabriel Teixeira

Devido aos problemas ambientais decorrentes dos gases do efeito estufa, reduzir as emissões de CO2 tornou-se mundialmente o objetivo e foco em pesquisa comum. As alternativas abordadas atualmente baseiam-se na substituição por fontes energéticas renováveis em lugar da queima de combustíveis fosseis e a captura e armazenamento de carbono dos gases de exaustão na pós-combustão antes de sua emissão a atmosfera. Ne...

Evaluation of MCM-41 and MCM-48 mesoporous materials as sorbents in matrix soli...

Santos, Luís Fabrício Santana; de Jesus, Roberta Anjos; Costa, José Arnaldo Santana; Gouveia, Lucas Gabriel Teixeira; de Mesquita, Maria Eliane

The MCM-41 and MCM-48 mesoporous materials were tested for extraction of thiamethoxam, thiacloprid, thiophanate-methyl, teflubenzuron, and bifenthrin from the fruit of soursop (Annona muricata), using liquid chromatography with ultraviolet diode array detection as the analysis technique. Extractions performed at one fortification level (0.5 mg kg−1, n = 3) resulted in recoveries in the ranges 75–106% and 76–95%...


A importância e consequência da produção sustentável para a sociedade

Sales, Marciel Rosa; Gouveia, Lucas Gabriel Teixeira; Ruzene, Denise Santos; Silva, Daniel Pereira

Currently, the globalization is now going on the opposite side of sustainability, since the greater the consumption and production, the more the environment is harmed, the residues produced, the atmospheric contamination and the exhaustive consumption of energy being the main cause of this impact. The increase in demand for products due to current spending habits, is seen as a major problem which consequently l...

Gouveia, Lucas Gabriel Teixeira; Farias, Isabella Santos; Ramos, Larissa Castor; Silva, Daniel Pereira; Ruzene, Denise Santos

Daily tons of waste, agricultural and industrial, both are dropped on the ground, landfills, rivers or applied to rude energy production processes, assaulting the environment. Alternatively, in actuality these residues have been valued as a source of raw material in different processes. In particular are the waste lignocelulosicos, formed mainly of cellulose, lignin and hemicellulose are rigid structures and re...

Polpação organosolv aplicada a fibras de resíduos lignocelulósicos

Farias, Isabella Santos; Gouveia, Lucas Gabriel Teixeira; Ramos, Larissa Castor; Silva, Daniel Pereira; Ruzene, Denise Santos

A few years ago are being studied methods that use agricultural waste to acquire chemicals with the highest market value as pulp for making paper and other cellulose derivatives. This work includes the systematic review regarding the pulping organosolv applied to lignocellulosic waste fibers in various matrices and their availability and low cost one factor that makes the use of such residues an attractive alte...

Revisão: biodiesel – gases emitidos, produção e sua influência na matriz energé...

Lima Filho, Laerson Ribeiro; Gouveia, Lucas Gabriel Teixeira; Ruzene, Denise Santos; Silva, Daniel Pereira

Biodiesel is a renewable fuel and has been backed by legislation since 2005. Since then it has been growing and its insertion in the national energy matrix is increasingly encouraged. Biodiesel is obtained through vegetable oils, animal fat and algae and, at least the first two, are abundant raw materials in Brazil. This fuel can be used to diversify the national energy matrix, as well as help the economy and e...
