“…Other advantages of biodiesel as compared to petro-diesel include reduction of most exhaust emissions, biodegradability, higher flash point, inherent lubricity [2]. Moreover, Production of biodiesel from animal fats is less expensive than traditional methods like extraction of biodiesel from trans-esterification of soyabean oil [3], [4], jatropha, vegetable oils, waste cooking oils [5], [6] etc.…”

Abstract-Electroplating waste samples were collected from various nearby industries in Aligarh, Uttar Pradesh (India), a prominent place for these industries and it was found that the concentrations of Cr +6 , Ni +2 , Cu +2 and Zn +2 ions were much more than the permissible norms of discharge which causes serious damage to the environment. To cater this issue, these heavy metal ions were extracted from the sample and then converted to their respective oxide nanoparticles by chemical precipitation and sol-gel methods respectively. And then, these nanoparticles were characterized by FTIR and XRD techniques. Also one of the major wastes produced in India is the butchery waste which causes severe health problems and is aesthetically unpleasant. This paper mainly focuses on the production of biodiesel from butchery waste by a new pathway utilizing heterogeneous nano-catalysts of Nickel(Ni +2 ) (extracted from electroplating waste) for the process of trans-esterification, which produces biodiesel which are mono-alkyl esters of long chain fatty acids (FAME-Fatty Acid Methyl Esters).

EXPLORATORY ANALYSIS APPLIED TO ATTENUATED TOTAL REFLECTANCE FOURIER TRANSFORM INFRARED (ATR-FTIR) OF BIODIESEL/DIESEL BLENDS. In this study, hierarchical cluster analysis (HCA) and principal component analysis (PCA) were used to classify blends produced from diesel S500 and different kinds of biodiesel produced by the TDSP methodology. The different kinds of biodiesel studied in this work were produced from three raw materials: soybean oil, waste cooking oil and hydrogenated vegetable oil. Methylic and ethylic routes were employed for the production of biodiesel. HCA and PCA were performed on the data from attenuated total reflectance Fourier transform infrared spectroscopy, showing the separation of the blends into groups according to biodiesel content present in the blends and to the kind of biodiesel used to form the mixtures.Keywords: HCA; PCA; diesel/biodiesel blends; exploratory analysis. INTRODUÇÃOO estudo de combustíveis alternativos aos derivados petroquí-micos tem recebido grande estímulo na última década no Brasil, especialmente com o desenvolvimento dos programas de incentivo a produção de novas matrizes energéticas, como é o caso do biodiesel adicionado ao óleo diesel mineral.A utilização do óleo diesel como combustível teve seu início amplamente reconhecido quando Rudolf Diesel patenteou o seu motor em 1892 e introduziu o primeiro motor diesel destinado a funcionar com óleo vegetal. Em 1900, ele abasteceu e utilizou o motor com óleo de amendoim por várias horas, com sucesso. Já em 1912, ele previu que, no futuro, o óleo vegetal poderia ser um combustível importante assim como o óleo diesel.1 Por razões tanto técnicas quanto econômicas, com o passar do tempo os óleos deram lugar ao diesel mineral.2 Na época, o baixo preço e a oferta abundante dos derivados de petróleo resultaram na escolha pelo diesel de petróleo. Em 1940, enormes reservatórios de petróleo foram encontrados, sua extração e refinamento foram relativamente fáceis e baratos. Em 1970, o monopólio de algumas nações e circunstâncias políticas geraram uma nova situação, o que obrigou os engenheiros e pesquisadores a desenvolver combustíveis alternativos e ambientalmente amigáveis. Desde então, há um interesse renovado na utilização de derivados de óleos vegetais em motores a diesel por várias razões, incluindo considerações políticas, preocupações ambientais e aspectos econômicos. Neste sentido, o biodiesel, que é constituído de uma mistura de alquil-ésteres de cadeia linear, é obtido pela reação de transesterificação dos triglicerídeos presentes em óleos e gorduras com álcoois de cadeia curta gerando como subproduto o glicerol. A importância do biodiesel como aditivo e até como possível substituinte do óleo diesel decorre do fato de que este biocombustível apresenta vantagens sobre o óleo diesel, pois é proveniente de fontes renováveis, não é tóxico e diminui as emissões de poluentes durante a sua combustão.4 O biodiesel produz cerca de 10% menos de energia que o diesel de petróleo, mas seu desempenho no motor é praticamente o mesmo em t...

“…Biodiesel obtainment: the biodiesel samples were obtained by transesterification double steps process (TDSP) as described by Samios et al 52,53 Internal standard stock solutions: ca 100 mg of hexadecyl acetate (HDA, CBiot, 100.0%) were accurately weighed, dissolved in heptane (Vetec), and diluted to 50 mL in a volumetric flask, to make a 2 mg mL -1 solution. The procedure was repeated to prepare methyl heptadecanoate (C17:0, Fluka 99.9%) stock solution.…”

GC-FID methodology validation for the fatty esters content determination in biodiesel with hexadecyl acetate as the internal standard

et al. 2017

Biodiesel purity expressed as fatty esters content is one of its most important quality parameters. Although several instrumental methods have been employed, gas chromatography with internal standard calibration has been the most used. Biodiesel is a very complex matrix, therefore finding a suitable internal standard (IS) is not straightforward. EN14103:2003 standard established methyl heptadecanoate (C17:0) as IS. Since this fatty ester is naturally present in some biodiesel feedstock as tallow, that standard was reviewed in 2011, and methyl nonadecanoate (C19:0) became the new IS. In turn, C19:0 produces a peak on the chromatogram that is difficult to resolve from methyl linoeate (C18:2) and metyl linolenate (C18:3) ones. In this paper, a GC-FID method for the determination of the esters content in methyl and ethyl biodiesel from canola and soy oils, using hexadecyl acetate as a new internal standard was validated. EN14103:2003 was used as reference method. Method selectivity, accuracy (t student parameter < 2.18 from both methods), repeatability (0.1 -0.4%), intermediate precision (0.2 -1.8%), and robustness (0.1 -1.6%) were investigated and considered appropriate for the scope.
