          Abstract

          In this study, biodiesel (methyl ester) was produced from Castor Oil (Ricinus communis L.) (CO) using sodium hydroxide (NaOH) and methanol (CH3OH) by the two-step transesterification method. Nine different fuel blends (2, 5, 10, 20, 30, 40, 50, 60 and 75% by volume blending with diesel) were prepared. The density values of Castor Oil Biodiesel (COB) and its blends were measured at the temperature range from 0 to 93°C in steps of 5°C and the kinematic viscosity values of COB and its blends were measured at the temperature range from 30 to 100°C in the steps of 5°C. The results showed that the density, kinematic viscosity, calorific value, flash point, pH, copper strip corrosion and water content of COB are 932.40 kg·m-3, 15.069 mm².s-1, 38.600 MJ·kg-1, 182°C, 7, 1a and 1067.7 mg.kg-1, respectively. The density and kinematic viscosity of fuel samples decrease as temperature increases; and also these properties decrease as a result of the increase in the amount of diesel in the blends.

          Neste estudo, o biodiesel (metil éter) foi produzido a partir do óleo de rícino (Ricinus communis L.) (CO, por suas siglas em inglês) usando hidróxido de sódio (NaOH) e metanol (CH3OH) através de um método de transesterificação de dois passos. Foram preparadas até nove misturas de combustível diferentes (2, 5, 10, 20, 30, 40, 50, 60 e 75% por volume de mistura com o diesel). Os valores de densidade do biodiesel de óleo de rícino (COB, por suas siglas em inglês) e as suas misturas foram calculados dentro do rango de temperatura de 0 a 93°C no passo de 5°C e os valores de viscosidade cinemática do COB e das misturas foram calculadas no rango de temperatura de 30 a 100°C no passo de 5°C. Os resultados demonstraron que a densidade, viscosidade cinemática, valor calorífico, ponto de fusão, PH, corrosão da faixa de cobre e conteúdo de água do COB eram de 932.40 kg·m-3, 15.069 mm².s-1, 38.600 MJ·kg-1, 182°C, 7, 1a e 1067.7 mg.kg-1, respectivamente. Os valores de densidade e viscosidade cinemática das amostras de combustível diminuem na medida em que aumenta a temperatura; e também essas propriedades diminuem em decorrência do aumento na quantidade de diesel nas misturas.

          En este estudio, se produjo biodiesel (metil éter) a partir de aceite de ricino (Ricinus communis L.) (CO, de sus siglas en ingles) utilizando hidróxido de sodio (NaOH) y metanol (CH3OH) a través del método de transesterificación en dos pasos. Se prepararon nueve mezclas diferentes (2, 5, 10, 20, 30, 40, 50, 60 and 75% dependiendo del volumen de la mezcla con biodiesel. Se estimaron los valores de densidad del Biodiesel de Aceite de Ricino (COB, de sus siglas en ingles) y sus mezclas en un rango de temperatura de 0 a 93°C en intervalos de 5°C y también se estimaron los valores de viscosidad cinemática de COB y sus mezclas dentro del rango temperatura comprendido entre 30 y 100°C en intervalos de 5°C. Los resultados mostraron que la densidad, la viscosidad cinemática, el valor calorífico, el punto de ignición, pH, la corrosión de la franja de cobre y el contenido de agua del COB son 932.40 kg·m-3, 15.069 mm².s-1, 38.600 MJ·kg-1, 182°C, 7, 1a y 1067.7 mg.kg-1, respectivamente. La densidad y la viscosidad cinemática de las muestras de combustible disminuyen a medida que aumenta la temperatura; y también estas propiedades disminuyen como resultado del aumento en la cantidad de biodiesel en las mezclas.

              Properties of various plants and animals feedstocks for biodiesel production.

              As an alternative fuel biodiesel is becoming increasingly important due to diminishing petroleum reserves and adverse environmental consequences of exhaust gases from petroleum-fuelled engines. Biodiesel, the non-toxic fuel, is mono alkyl esters of long chain fatty acids derived from renewable feedstock like vegetable oils, animal fats and residual oils. Choice of feedstocks depends on process chemistry, physical and chemical characteristics of virgin or used oils and economy of the process. Extensive research information is available on transesterification, the production technology and process optimization for various biomaterials. Consistent supply of feedstocks is being faced as a major challenge by the biodiesel production industry. This paper reviews physico-chemical properties of the plant and animal resources that are being used as feedstocks for biodiesel production. Efforts have also been made to review the potential resources that can be transformed into biodiesel successfully for meeting the ever increasing demand of biodiesel production.
