The present article demonstrates a superior catalytic performance of glycerol-enriched calcium oxide for biodiesel production than other calcium-based counterparts. The proficiency of glycerol-enriched calcium oxide in catalyzing the methanolysis of crude Jatropha curcas oil containing high free fatty acids content was systematically researched by examining the effects of glycerol dose, temperature, time, methanol-to-oil molar ratio and calcium oxide (CaO) amount on the process. Acid value of oil was lowered by 49 times and the maximum oil conversion of 96.1% was reported after the methanolysis reaction that indicated the improved performance of calcium oxide, after its treatment with glycerol, in accelerating biodiesel production from crude oil with very high free fatty acids amount. An interaction between the reaction variables, their influence on the methanolysis and optimum conditions affecting the process were moreover determined by means of the regression analysis (response surface methodology). The statistical analysis suggested that both CaO amount and mole ratio of methanol-to-oil had a significant impact on the current biodiesel production process.Graphical Abstract

Cuide su colon y cómprese un coche el "efecto masa " y los libros diálogos con el clon

Marcos Sánchez

Otra noticia: desesperación-indignación de un millar de manifestantes frente a la entrada de la cárcel de Abu Ghraib en protesta por asuntos de torturas y malos tratos infligidos a prisioneros de guerra. Aún hay más: en Bagdad, cuatro personas han muerto al explotar un vehículo blindado en el centro de la ciudad, donde también ha habido seis muertos en un atentado suicida... De repente, todo cambia; se transforma en milésimas de segundo en un surtido de colores que anuncian que debemos adquirir el no va más de los productos lácteos. Uno que garantiza a nuestro colon que va a gozar lo suyo refrescándose, tonificándose y haciéndose más turgente y sano. La ráfaga no dura más de cinco segundos, pero ha dejado ante tus ojos una estela de incredulidad que te deja pasmado: ¿será cierto lo que acabo de ver hace seis segundos tan sólo? ¿No me encontraba contemplando imágenes de una guerra? Había cuerpos mutilados por ahí. Pero si resultaba espantoso...
