“…Other studies reported by the same research group used the preceding pilot plant to transform residual fish oil by quick pyrolysis. 28,29 Using similar techniques of sampling and separation as before, GC, GC-MS, 1 H and 13 C NMR as analytical means, they were able to identify some 70% in volume of the LBO fraction. The main hydrocarbon families found were: olefins (26.5% v/v), aromatics (17% v/v), isoparaffins (8.3% v/v), naphthenes (6.1% v/v), n-paraffins (4.5% v/v) and C14+ (5.3% v/v).…”

“…Studies using different types of zeolites were performed by Santos et al 31 In this case, the proposed objective was to obtain branched hydrocarbons isomers and aromatics able to upgrade some properties of gasoline. 28 The oil feed studied was a commercial soybean oil and the catalytic transformations were performed between 400 and 500 ºC. Samples of 1 g oil were injected over a catalyst bed of 1.5 g, maintained at the reaction temperature and the liquid phase issued from the transformation collected in a low temperature flask before analysis.…”

Os processos industriais mais utilizados na produção de combustíveis líquidos semelhantes ao diesel usam catalisadores homogêneos básicos através das metanólise e etanólise de óleos tais como os de soja, canola, palma entre outros. Desse modo, se obtém o biodiesel. Por sua vez, transformações termo-catalíticas usando as facilidades existentes nas refinarias de petróleo são alternativas que merecem atenção devido a sua viabilidade econômica. De fato, três processos industriais já estão em funcionamento e novos projetos estão em fase final para comercialização. O presente trabalho analisa os experimentos já realizados por pesquisadores brasileiros nas áreas do craqueamento, do craqueamento catalítico e do hidrocraqueamento catalítico dos óleos vegetais puros ou modificados. A partir dos resultados descritos, são sugeridas novas direções destas pesquisas para os próximos anos.The most used industrial processes for the production of liquid fuels like diesel type are based on the methanolysis and ethanolysis of various oil reactants, such as palm, soybean and rapeseed oils, in the presence of homogeneous base catalysts. However, thermal and catalytic transformations of vegetable oils using available reactors and industrial processes are possible alternatives and deserve attention. In fact, three industrial processes are operating and new projects are announced. The present work analyses the experimental studies performed up to now by Brazilian researchers in the field of cracking, catalytic cracking and hydrocracking of pure or modified vegetable oils. From the published results, some research areas for the near future are suggested.

Faculty of Natural SciencesInstitute of Aquaculture Doctor of PhilosophyBy-products and mortalities from aquaculture have often posed significant challenges to the industry because of their low value resulting in high costs and environmental impact from their disposal. However increasing interest is being expressed in their utilisation to add value to the aquaculture industry and provide synergies with industries which had previously been in competition with aquaculture.Current and prospective processing by-product and farm mortality utilisation strategies were reviewed along with regulations and standards which aim to control their use and protect against human and animal health hazards.The role of aquaculture and fishery by-products in the supply of fishmeal was investigated and it was found that both sectors had the potential to contribute to increasing global supply. There were significant quantities of processing by-products identified which could be directed to fishmeal manufacture but there were also significant amounts of fish production which were not being processed in some regions and could also add to supplies. Processing by-products from aquaculture species often exceed 50% of the production by mass and therefore their efficient utilisation is of significant importance to the overall performance of the value chain. Their utilisation ii strategies are diverse and in some circumstances offer the possibility to add significant value.Life Cycle Assessment (LCA) is increasingly being used to inform decision makers and consumers about the environmental performance of goods and services to make choices on best practices and informative decisions on purchasing choices. Current methodology in LCA was critiqued and developed to be used for identifying disproportionate impacts from by-product industries and comparative assessment of the eco-efficiency of value chains from Thai shrimp, Vietnamese Pangasius catfish and Scottish salmon aquaculture.New LCA methodology was developed assessing the eco-efficiency of co-products as a whole and in relation to a tonne of edible yield. Measuring the impact of the by-product industry in relation to their edible yield gave different results to measuring their ecoefficiency between the three study species. It was found that the Thai shrimp value chain was the most eco-efficient when by-products were directed to chitosan and hydrolysate manufacture, but production of the salmon was the least impacting between the species in terms of edible yield. Pangasius was the most environmentally impacting of the three species value chains using both methods. It was also found that the upstream impacts of fish and shrimp production, especially feed manufacture, contributed most to the environmental impact in most circumstances, using both economic and mass allocation.Although the methodology produced interesting results, there were some drawbacks and the data sets also had several gaps which led to some assumptions, which could have skewed the results and interpretation.The cau...

Recebido em 6/2/09; aceito em 29/10/09; publicado na web em 26/3/10 EVALUATION OF BIOFUEL DERIVED FROM LIGNOCELLULOSIC BIOMASS FAST PYROLYSIS BIO-OIL FOR USE AS GASOLINE ADDICTIVE. A biofuel was prepared from acid aqueous fraction (pH = 2) of bio-oil produced by fast pyrolysis (Bioware Technology) of lignocellulosic biomass (sugar cane residue) and tested in blends (2, 5, 10 e 20% v/v) with gasoline type C (common) marketed in Brazil. The specification tests made in the Refinery President Getúlio Vargas (PETROBRAS) showed increasing in the octane number (MON) and antiknock index (AKI) with reduction in the residue generation during the combustion. The physicochemical characteristics of the biofuel were similar that combustible alcohol allowing its use as gasoline additive.Keywords: distillation curve; induction period; steam pressure. INTRODUÇÃOA demanda por energia está aumentando rapidamente, devido ao crescimento da população e seus anseios tecnológicos. A população mundial dedicou-se às indústrias de carvão e petróleo, mas com a exploração desenfreada de reservas naturais e a questão do efeito estufa, existe atualmente grande interesse para a produção sustentável de energia. As fontes de energia renováveis, como a biomassa, têm papel fundamental no contexto energético, ambiental e sócio-econômico. 1A biomassa consiste em elementos como carbono, hidrogênio, oxigênio e nitrogênio. O enxofre está presente em menores proporções e alguns tipos de biomassa contêm também porções significantes de espécies inorgânicas.2 As fontes de biomassa incluem madeira e resíduos de madeira, colheitas agrícolas e seus resíduos, resíduo sólido municipal, resíduos animais, resíduo de processamento de alimento, plantas aquáticas e algas.3 Os principais constituintes moleculares da biomassa são hemicelulose, celulose e lignina e um dos principais processos de conversão é a pirólise. 4 Vários mecanismos já foram propostos para as possíveis rotas de reação que ocorrem durante a pirólise de biomassa.5-8 O ácido acético é o principal produto da decomposição térmica. Durante a pirólise ocorre a formação de água por desidratação, de ácido acético pela eliminação de grupo acetila originariamente ligado a unidades de xilose, de furfural pela desidratação da xilose, de ácido fórmico a partir de grupos carboxílicos do ácido urônico e de metanol a partir de grupos metoxilas também do ácido urônico.O processo de pirólise produz combustíveis líquidos com alto rendimento, 9 porém, ainda existem alguns desafios que precisam ser enfrentados no uso destes produtos. O óleo resultante da pirólise de biomassa, denominado genericamente de bio-óleo, além de ser um combustível líquido renovável, sendo esta a principal vantagem sobre derivados do petróleo, pode ser usado para a produção de inúmeras substâncias químicas. 10O uso de derivados do bio-óleo como combustível em veículos de transporte é tecnicamente possível, mas existe a necessidade de pesquisas e investimentos.11-14 Pesquisas envolvendo separação e transformação de componentes de bio-óleo em és...
