This paper discusses the synthesis of biodiesel catalyzed by solid base of K(2)CO(3)/HT using Jatropha curcas oil as feedstock. Mg-Al hydrotalcite was prepared using co-precipitation methods, in which the molar ratio of Mg to Al was 3:1. After calcined at 600 degrees C for 3 h, the Mg-Al hydrotalcite and K(2)CO(3) were ground and mixed according to certain(More)
Production of biodiesel from the transesterification between soybean oil and methanol was conducted in this study by a membrane reactor, in which ceramic membrane was packed with MCM-41 supported p-toluenesulfonic acid (PTSA). Box-Behnken design and response surface methodology (RSM) were used to investigate the effects of reaction temperature, catalyst(More)
Experiments were conducted to characterize fire properties of wood exposed to the certain external heat flux and under variety of wood moisture content. Six kinds of Indonesian wood: keruing, sono, cemara, kamper, pinus, and mahoni were exposed to radiant heat from a conical heater, result in appearance of a stable flame on the wood surface caused by(More)
In order to simulate catalytic reactive distillation process for biodiesel production via transesterification accurately, the Antoine parameters of biodiesel and NRTL binary interaction coefficients were regressed using Aspen Plus Data Regression function according to the data in literatures. Then vapor pressure of biodiesel under different temperature and(More)

Cyanobacteria were catalytically pyrolyzed over Mg-Al layered double oxide/ZSM-5 composites (MgAl-LDO/ZSM-5) to produce bio-oil. MgAl-LDO/ZSM-5 with a Mg/Al molar ratio of four was proved to be the best catalyst. Under the optima condition that the final temperature was 823K, heating rate was 10K/min and catalyst/algae mass ratio was 0.75, a maximum yield(More)
