Direct 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 کاملCorrection: 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 کاملNovel sulfonated carbonaceous materials from p-toluenesulfonic acid/glucose as a high-performance solid-acid catalyst
1566-7367/$ see front matter Crown Copyright 2 doi:10.1016/j.catcom.2010.01.010 * Corresponding authors. Tel./fax: +86 (21)6425382 E-mail addresses: [email protected] (J. Ren), w Wang). A novel carbon-based solid-acid catalyst was simply prepared for the first time by the thermal treatment of p-toluenesulfonic acid (TsOH) with D-glucose at 180 C in a sealed autoclave and it was proved to ha...
متن کاملGlucose production from saccharides using layered transition metal oxide and exfoliated nanosheets as a water-tolerant solid acid catalyst.
The layered transition-metal oxide HNbMoO(6) is demonstrated to exhibit remarkable catalytic performance for the hydrolysis of saccharides such as sucrose, cellobiose, starch, and cellulose, attributable to water tolerance and the facile accessibility of saccharides into the strong acidic interlayer gallery of the solid.
متن کاملGlucose production from hydrolysis of cellulose over a novel silica catalyst under hydrothermal conditions.
A novel silica catalyst was synthesized by evaporation-induced self-assembly (EISA) method and tested for the catalytic selective hydrolysis of cellulose to glucose. This silica catalyst exhibited a higher catalytic activity than other oxides prepared by the same method, such as ZrO2, TiO2, and Al2O3. Using silica as a catalyst, cellulose was selectively hydrolyzed into glucose with a glucose y...
