Tribo-electrostatic beneficiation of fly ash for ash utilizationKorean Journal of Chemical Engineering - Tập 18 - Trang 531-538 - 2001
Jae-Kwan Kim, Sung-Chul Kim
The study was conducted to obtain the scale-up factor and the optimum design
criteria for the development of a commercial scale electrostatic separator using
a continuous, bench-scale electroseparator composed of two vertical electrode
plates and an ejector-tribocharger. Tests of the charge density and separation
efficiency to study the removal possibility of unburned carbon from coal fly ash
were... hiện toàn bộ
Chemical reaction engineering in the chemical processing of metals and inorganic materialsKorean Journal of Chemical Engineering - Tập 20 - Trang 415-428 - 2003
Hong Yong Sohn
In traditional chemical reaction engineering, it is possible to incorporate only
the simplified aspects of fluid flow, mixing, and mass/heat transfer into the
analysis of chemical reaction rates and reactor design. As a consequence of the
advent of high-speed, high-capacity computing capacity, complex processes
involving chemical reactions have become amenable to analysis and modeling. This
has al... hiện toàn bộ
Composition modulation of Cu/Cu2O/CuO nanoparticles supported on carbon for p-nitrophenol reductionKorean Journal of Chemical Engineering - Tập 36 - Trang 851-859 - 2019
Jia Li, Wei Liu, Yongxin Ding, Likui Liu, Fang Li, Qiming Li
Porous carbon supported Cu/Cu2O/CuO ternary catalysts were fabricated by
pyrolysis, in which composition modulation of Cu/Cu2O/CuO was successfully
realized by adjusting annealing atmosphere. The correlation between annealing
atmosphere and composition of Cu/Cu2O/CuO ternary nanoparticles was deeply
investigated. XRD and SEM measurement shows that the composition proportion of
Cu/Cu2O/CuO can be e... hiện toàn bộ
Novel polymorphous aluminosilicate nano minerals: Preparation, characterization and dyes wastewater treatmentKorean Journal of Chemical Engineering - Tập 34 - Trang 2406-2417 - 2017
Saleh Nosrati, Kumars Seifpanahi-Shabani, Mohammad Karamoozian
Polymorphous aluminosilicate, such as Andalusite, Kyanite and Sillimanite, were
prepared and characterized by XRF, XRD, FT-IR and SEM analysis. These cheap and
accessible nanoparticles were used for removal of Disperse Red 177 and Disperse
Blue 60 dyes. The adsorption process was held in a batch system considering the
effects of major parameters consist of pH, adsorbent dosage, dye initial

A kinetic model for glycerol chlorination in the presence of acetic acid catalystKorean Journal of Chemical Engineering - Tập 27 - Trang 66-72 - 2010
Zheng-Hong Luo, Xiao-Zi You, Hua-Rong Li
A kinetic model for the chlorination of glycerol with hydrochloric acid in the
use of acetic acid as catalyst is presented in this study. The model is based on
a comprehensive chlorination mechanism, taking the formation of
1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol into account while ignoring
the formation of any intermediate in the chlorination system. Simulations were
carried out under... hiện toàn bộ
High temperature desulfurization over nano-scale high surface area ceria for application in SOFCKorean Journal of Chemical Engineering - Tập 25 - Trang 223-230 - 2008
Rajesh Shivanahalli Kempegowda, Navadol Laosiripojana, Suttichai Assabumrungrat
In the present work, suitable absorbent material for high temperature
desulfurization was investigated in order to apply internally in solid oxide
fuel cells (SOFC). It was found that nano-scale high surface area CeO2 has
useful desulfurization activity and enables efficient removal of H2S from feed
gas between 500 to 850°C. In this range of temperature, compared to the
conventional low surface ar... hiện toàn bộ
Microfiltration of yeast cells in an internal filter reactorKorean Journal of Chemical Engineering - Tập 13 - Trang 404-408
Woo Gi Lee, Beom Soo Kim, Ho Nam Chang
Microfiltration was carried out in a newly-developed internal filter reactor
system (stainless steel membrane filter, pore size=2 or 10 μm) using yeast cells
ofSaccharomyces cerevisiae ATCC 24858, industrialS. cerevisiae, and recombinant
yeast RH 51. The filter performance was measured in terms of filtrate flux and
retention coefficient of cell, and was highly influenced by agitation speed and
