This work investigated the viability of a non-edible oil obtained from raphia africana in production biodiesel using novel heterogeneous catalyst derived turtle shells (Centrochelys sulcata). The study also proposed use acetone as co-solvent to enhance solubility reacting mixtures. were calcined at 900oC for 3hr, impregnated KOH improve its activity and then supported with activated carbon prod...

The title compound, propyl gallate (III), is an important substance popularly used in the food, cosmetic and pharmaceutical industries. Current chemical syntheses of this compound are based on acylation supported by thionyl chloride, DIC/DMAP or Fischer esterification using a range homogenous heterogenous catalysts. In paper, efficient, green, straightforward, economical method for synthesizing...

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 tightening standards of nitrogen oxides emission from industrial plants encourage nitric acid producers to search for new efficient solutions meet the stringent limits. Industrial practice and patent literature show that effectiveness deNOx (SCR) deN2O technology is affected not only by type shape catalyst, but also method its installation in a heterogenous catalytic reactor. article presen...

Aqueous biphasic catalysis is a convenient approach to convert organic, partially soluble molecules in water. However, converting more hydrophobic substrates is much more challenging as their solubility in water is extremely low. During the past ten years, substantial progress has been made towards improving the contact between hydrophobic substrates and a hydrophilic transition-metal catalyst....

This paper argues that Information Technology (IT) needs to be demystified, through critical consciousness, for educators to focus on IT as a means to enhance learning. It goes on to define the technical, sociohistorical and political-ideological levels of IT and to identify four theoretical constructs: tutorial, machine-as-human, tool kit and catalyst. Pervading these constructs is the underst...

CO/CO2-Methanation can contribute to the storage of intermittently produced renewable energy. In order be able design this heterogenous catalytic process well with models, a solid diffusion model is necessary. Thus, effects selection are simulated in context under steady-state and unsteady-state conditions. Therefore, dusty gas Wilke-Bosanquet compared binary friction model. The operation condi...
