[ 1 ] - Bioremediation of lignocellulosic wastes of food industries by Aspergillus flavus as food and feed additive protein by solid-state fermentation process
The lignocellulosic wastes produced in food industries are suitable raw materials for the production of biological products. In this study, the solid state fermentation of Aspergillus flavus on lignocellulosic wastes was evaluated for microbial protein production. The fraction of the full factorial method was applied for experiment design and process optimization. The results analysis was perfo...
[ 2 ] - Esterification of Waste Cooking Oil Followed by Transesterification by CaO Nanoparticles: Application of Taguchi Methodology
In order to produce biodiesel from waste cooking oil and optimize its yield, a two-stage process of esterification/ transesterification has been used in this study. First, we used the acidic catalysts H2SO4 in order to diminish the content of free fatty acid (FFA) in oil that caused reducing the oil acidity from 6.1% to 0.57% through esterification. Then, the biodiesel was produced by transeste...
[ 3 ] - Modification of Nano Clinoptilolite Zeolite Using Sulfuric Acid and Its application Toward Removal of Arsenic from Water Sample
Zeolites are widely used in wastewater and contaminated water refinement due to their great adsorption properties. However, Clinoptilolite (as one type of Zeolites) has a relatively low adsorption capacity at least for arsenic ions. Therefore, in order to increase the adsorption capacity, natural Clinoptilolite was modified with sulfuric acid and various tests were then conducted to determine t...
[ 4 ] - DFT Study of Nitrous Oxide Adsorption on the Surface of Pt-Decorated Graphene
In the present study we search potential of Pt-decorated graphene (PtG) as a new nanostructure adsorbent for nitrous oxide (N2O) using density functional theory (DFT). After fully relaxation of different possible orientations of N2O-PtG complex, we distinguished two optimized configurations for this system; 1- terminal N-side of gas is oriented towards Pt so that the molec...
