In this study, Jatropha curcas oil was used as feedstock for biodiesel production by alkali-catalyzed methanolysis. To establish the optimum conditions for biodiesel production, effects of certain factors were investigated, these factors are oil-to-methanol molar ratios (1:4 1:8), KOH catalyst concentrations (0.5 1.5% w/w oil), reaction temperatures (50 70oC), and reaction times (55 90minutes)....

A study was conducted in 2010 to investigate the effects of crude oil contaminated soil on biomass accumulation inJatropha curcas seedlings in Asaba, Delta State, Nigeria. Oil levels used were 0.0, 2.0, 4.0, 6.0, 8.0 and 10.0% w/w. The trial was arranged in a randomized complete block design with four replications and monitored for 12 weeks after transplanting. Results showed that contamination...

O objetivo deste estudo foi traçar o perfil epidemiológico dos acidentes por plantas tóxicas no Estado do Pará, Brasil. Para isso, realizado um descritivo, observacional e transversal de casos intoxicações registradas banco dados Centro Informações Toxicológicas (CIT), Hospital Universitário João Barros Barreto Belém-Pará, período janeiro 2007 a maio 2018. Os resultados revelaram 14.952 notific...

En el ejido Cinco de Febrero, Champotón, Campeche, se realizaron trabajos transferencia tecnología con Jatropha curcas L., variedad “Doña Fernanda”, para valorar su factibilidad como opción desarrollo rural, respetando la cultura milpa, bajo un sistema agrosilvopastoril. Se entrevistó a los interesados en proyecto y estos datos describieron las condiciones socioeconómicas agropecuarias del ejid...

The synthesis of biodiesel from Jatropha curcas by transesterification is kinetically controlled. It depends on the molar ratio, reaction time, and temperature, as well catalyst nature quantity. aim this study was to explore low-cost, inedible J. seed oil utilizing both homogenous (potassium hydroxide; KOH) heterogenous (calcium oxide; CaO) catalysis. In effort, two steps were used. First, free...

the jatropha curcas l., a plant belongs to euphorbiaceae family, which has great economic and medicinally value. there is high amount of oil in seeds of this plant. because of low germination ability of seed, propagation of jatropha curcas via seed is not usual. the purpose of this work is optimizing of jatropha curcas tissue culture for optimization of callus formation and propagation through ...

In the present study, the high viscosity of the jatropha curcas oil was decreased by preheating. The effect of fuel inlet temperature on performance of diesel engine is evaluated. A single cylinder, four stroke, constant speed, air cooled, direct injection diesel engine developing a power output of 3.7 kW at 1500 rev/min typically used in agricultural sector was tested using neat jatropha oil a...

Esters of plant oils are preferred to parent oils if used as fuels in diesel engines because esterification reduces the viscosity of plant oils and makes it comparable to that of diesel. The present work mainly deals with the effect of storage time on the quality of plant oils and their esters with respect to mainly FFA content, viscosity and change in weight. The study was carried out for a pe...
