Correction: Direct production of biodiesel from high-acid value Jatropha oil with solid acid catalyst derived from lignin
Correction We found an important error in our published paper [1]. On page 7, Section: One-step conversion of Jatropha oil to biodiesel, line 3, we wrote a reaction temperature of 120degreesC. The correct temperature should be 220degreesC. The pressure was also omitted from the same reaction description and should be 7.1 MPa. Direct production of biodiesel from high-acid value Jatropha oil with...
متن کاملDirect production of biodiesel from high-acid value Jatropha oil with solid acid catalyst derived from lignin
BACKGROUND Solid acid catalyst was prepared from Kraft lignin by chemical activation with phosphoric acid, pyrolysis and sulfuric acid. This catalyst had high acid density as characterized by scanning electron microscope (SEM), energy-dispersive x-ray spectrometry (EDX) and Brunauer, Emmett, and Teller (BET) method analyses. It was further used to catalyze the esterification of oleic acid and o...
متن کاملBiodiesel Production with Solid Catalysts
Biodiesel is usually produced by transesterification of vegetable oils or animal fats with chemical catalysts, especially in the presence of strong acidic or basic solutions, such as hydrochloric acid, sulphuric acid, sodium hydroxide, sodium methoxide and potassium hydroxide. Homogeneous alkali catalysts can convert triglycerides to their corresponding fatty acid methyl esters (FAMEs) with hig...
متن کاملFatty acid and biodiesel characteristics Ethiopian Jatropha (Jatropha curcas L.) provenances
For determining the fatty acid characteristics and biodiesel quality of Ethiopian Jatropha provenances, the study was conducted in five regions namely Southern Nation Nationalities Peoples Regional State (SNNPRS), Amhara region, Tigria region, Oromia region and Benishangul Gumuz Regions, where physic nut is found abundantly. For each region, representative sampling sites were selected following...
