The antioxidant potential of a novel additive, named maleimide p-CH3, and the synergistic effect on biodiesel stabilization when combined with a traditional synthetic antioxidant (e.g., propyl gallate (PG)) as well as alternative additives (e.g., alizarin (ALZ) and citric acid (CA)) were investigated. The additives were combined in binary and/or ternary blends at low concentrations and their effectiveness against soybean biodiesel oxidation in the absence and presence of metal was tested. The effectiveness of binary and ternary blends was also evaluated by the Rancimat® method and compared with total acid number (TAN). The results showed that the combinations presented synergetic effects and were effective in stabilizing biodiesel in accordance with the minimum requirements of EN 14214 and also revealed that the mixture containing PG and p-CH3, even at low concentrations, can be successfully applied for biodiesel preservation. In summary, we report that the biodiesel stability can be obtained by using a reduced amount of additives, suggesting that biodiesel shelf life can be improved in association with a cost reduction when compared to the use of conventional antioxidants.

In the present investigation, a biodiesel derived from soybean oil with 1, 4-Dioxan was tested as an alternative fuel for agricultural diesel Engine. The performance and emissions studies were conducted for both neat and blended biodiesel (B25, B50, B75 and B100) with and without antioxidant and the comparison is also made with petroleum diesel. On using biodiesel, the emissions of HC and NOx were less compared to diesel. The brake thermal efficiency of B25+1, 4-Dioxan and mechanical efficiency of B50+1, 4-Dioxan is nearly similar to that of diesel.

A sojicultura é caracterizada como a monocultura de maior dimensão econômica mundial. Esse fato tem despertado o desenvolvimento de pesquisas em nível mundial, cuja finalidade é compreender os impactos negativos do processo de expansão de seu cultivo. Este artigo tem por objetivo apresentar o mapeamento da produção científica internacional sobre os impactos negativos decorrentes do cultivo e expansão da cultura da soja. O escopo da pesquisa é composto por 389 artigos, coletados das bases de dados Scielo e Web of Science. Os resultados são apresentados sob as perspectivas de: 1) distribuição anual dos artigos; 2) caracterização dos artigos mais citados; 3) países que mais publicaram; e 4) clusters de palavras-chave. Foi possível perceber uma elevação da concentração de publicações a partir do ano de 2000, principalmente relacionadas ao bioma Amazônia. Os países que mais publicaram no período analisado foram os Estados Unidos, Brasil e China. A co-ocorrência de palavras-chave mais utilizadas foi “deforestation, systems, brazil, assessment, soybean oil, soybean biodiesel”. Dos 389 artigos encontrados, observou-se que a pesquisa está centrada nos estudos relacionados ao desmatamento, aumento da produção de biodiesel, contaminação dos recursos hídricos, mudanças climáticas e o uso dos agrotóxicos, entretanto há estudos crescentes sobre os impactos positivos no ambiente com enfoque em novas tecnologias, como a integração lavoura-pecuária e floresta, nos sistemas de produção para a mitigação de danos ao meio ambiente, sobretudo com o potencial para o sequestro de carbono, além de orientarem para o uso racional dos recursos hídricos.

When blended together, homopolymers A and B will normally macrophase-separate into relatively large (≫1 μm) A-rich and B-rich phases, between which exists poor interfacial adhesion, due to a low entropy of mixing. The size scale of phase separation in such a blend can be reduced, and the extent of interfacial A-B contact and entanglement enhanced, via addition of an emulsifying agent such as an AB diblock copolymer. Diblock copolymers consist of a long sequence of A monomers covalently bonded to a long sequence of B monomers. These materials are surface-active and decrease interfacial tension between immiscible phases much in the same way as do small-molecule surfactants. Previous studies have clearly demonstrated the utility of block copolymers in compatibilizing homopolymer blends and enhancing blend properties such as fracture toughness. It is now recognized that optimization of emulsified ternary blends relies upon design considerations such as sufficient block penetration into a macrophase (to avoid block slip) and prevention of a copolymer multilayer at the A-B interface (to avoid intralayer failure).
