Rubber seed oil (RSO) and its sodium soap were pyrolysed in a batch reactor to obtain low molar mass organic substances. The pyrolitic oil of RSO was redistilled and the distillates were characterized by GC-MS and FTIR. Density, acid value, saponification value and ester values were also measured according to the ASTM standard methods. A similar analysis was done for samples taken out at differ...

BACKGROUND Microalgal triacylglycerides (TAGs) are a promising sustainable feedstock for the biofuel, chemical and food industry. However, industrial production of microalgal products for commodity markets is not yet economically viable, largely because of low microalgal productivity. The latter is strictly dependent on initial-biomass-specific (IBS) light availability (i.e. ratio of light impi...

background : the sequencing batch reactor (sbr) is one of the most widely used systems in sewage treatment because of the simplicity of the process, flexibility of operation in the removal of nutrients, and the ability to be used in different scales. the aim of this study was to evaluate the efficiency of the sbr in the removal of organic matter (nitrogen and phosphorus) from synthetic wastewat...

alkaline hydrolysis of ethyl acetate is essentially an irreversible and second order reaction. industrial importance of the reaction product, sodium acetate, necessitate for process improvement in terms of maximum conversion and economical usage of raw materials. statistical design of experiments was utilized to enhance conversion in both batch and plug flow reactors.a full two level factorial ...

The objective of this study is to evaluate the decolorization of Methylene Blue (MB) by an up-flow anaerobic sludge blanket (UASB) reactor. The UASB reactor was operated under batch condition with total treatment volume of 3l and operation time of 24 h per batch. It was found that the color of MB disappeared within a few minutes after entering into the UASB reactor due to reduction by anaerobic...

The consumption of petroleum products has been significantly increasing year by year. Petroleum offers a tremendous convenience for our life, and our daily life would be quite different without it. However, the depletion of petroleum is creeping under our foot. Lignocellulosic biomass has unlimited potential because it is possible to substitute for petroleum as energy and chemical sources. Rece...

Enhancement of the production yield of boron nitride nanotubes (BNNTs) with high purity was achieved using an amorphous boron-based precursor and a nozzle-type reactor. Use of a mixture of amorphous boron and Fe decreases the milling time for the preparation of the precursor for BNNTs synthesis, as well as the Fe impurity contained in the B/Fe interdiffused precursor nanoparticles by using a si...

A laboratory-scale anaerobic sequencing batch reactor (ASBR) was operated using a glucose-based synthetic wastewater to study the effects of tylosin, a macrolide antimicrobial commonly used in swine production, on treatment performance. The experimental period was divided into three consecutive phases with different influent tylosin concentrations (0, 1.67, and 167 mg/L). The addition of 1.67 m...
