The effect of potassium modification on structural properties and catalytic activity of copper and iron containing SBA-16 catalysts for selective oxidation of ethanol
(Elsevier Ltd, 2019)
Copper and iron SBA-16 catalysts were synthesized using hydrothermal method and modified with potassium. XRD patterns showed that characteristic peaks of SBA-16 for all catalysts did not destroy with metal loading. The ...
Synthesis and characterization of modified diatomite-leaf-like cuO nanosheet composites
(Trans Tech Publications Ltd, 2018)
In this work, firstly we described the effect of freeze drying on modification of raw diatomite. And then, modified diatomite-leaf-like copper oxide (CuO) nanosheet composite was successfully prepared by surfactant-free ...
Size controllable synthesis and characterization of cuO nanostructure
(Trans Tech Publications Ltd, 2018)
In this study, copper oxide (CuO) nanostructures were successfully prepared by adding EG (ethylene glycol) and PEG (4000, 8000) (polyethylene glycol) via an in-situ chemical precipitation method. EG and PEG (4000, 8000) ...
Estimation of the bond grindability index from the sink-float test data of two different particulate pumices
(Taylor and Francis, 2012)
In this study, equations for estimating the Bond grindability index by the sink-float test data of pumice were developed. Primarily, the cumulative weight and porosity content of the floating fraction were determined for ...
The effects of powder filling on the kinetic breakage parameters of natural amorphous silica
(Taylor and Francis Inc., 2017)
In this study, the effects of powder filling were investigated on natural amorphous silica at batch grinding conditions based on a kinetic model. For this purpose, first eight different mono-sized fractions were carried ...
Effects of mill speed on kinetic breakage parameters of four different particulate pumices
(Taylor and Francis, 2013)
In this study, the effect of mill speed was investigated on different particulate pumice samples at batch grinding conditions based on a kinetic model. For this purpose, S i and B i,j equations were determined from the ...
Computer simulation of product size distribution of a laboratory ball mill
(Taylor and Francis Inc., 2011)
In this study, a computer simulation of a suitable matrix notation of the Broadbent and Callcott grinding model was written. First, a chromite sample was ground in the laboratory type batch ball mill at different grinding ...
The evaluation of grinding process using artificial neural network
(Elsevier, 2016)
Ball milling has been the subject of intensive research for the past few decades. It is indeed the most encountered mineral processing operation of size reduction. Known as the most energy inefficient process, focus has ...
Clarification and the concentration of apple juice using membrane processes: A comparative quality assessment
(2010)
The aim of this study was to evaluate the potential of integrated membrane processes for the clarification and the concentration of apple juice, taking into account the impact on the product quality. The fresh apple juice, ...
The use of factorial design for modeling membrane distillation
(2010)
A two-level factorial experimental design was used to investigate the influence of the main operating parameters on evaporation flux and soluble solid content of apple juice during concentration through osmotic distillation ...
