Kinetic Analysis of H2S Removal Over Several Mesoporous Metal Mixed Oxides During Hot Coal Gas Desulfurization in a Fixed-Bed Reactor Using the Deactivation Kinetics Model

Authors: Yong-Son Hong
Comments: 1 Page.

DKM has not considered the detailed characteristic parameters of the solid sorbent in such a microscopic way as unreacted shrinking core model(SCM) or general regression model (GRM) but in a macroscopic way. Therefore, DKM can be extensively applied to the kinetic analysis of noncatalytic heterogeneous reaction or adsorption processes without the requirement of structural property for sorbents.

Analysis of the Fatty Acid Composition in Grape Seed by GC / MS

Authors: Ri Hyon Il, Kim Tae Mun, Kang Myong Su
Comments: 6 Pages. analytical chemistry

Fatty acids composition in grape seed are analyzed. Soxhlet extraction method toextract the fatty oil in the grape seed oil,with potassium hydroxide methanol solution to methyl esterof fatty acid in fatty oil,and gas chromatography-mass spectrometry instrument is analyzed. The results showthat 6 fatty acids are detected in the mountain grape seed,the major fatty acids are linoleic acid and oleic acid.

Kinetic Reevaluation on Adsorption of Co(ii), Hg(ii) and Ag(i) from Fuel Ethanol by Silica Gel Supported Sulfur-Containing Pamam Dendrimers[fuel 199 (2017) 91–101 and 206 (2017) 80–88]

Authors: Yong-Son Hong, Hong-Chol Jin
Comments: 3 Pages.

In our letter, the adsorption of Co(II), Hg(II) and Ag(I) from fuel ethanol by silica gel supporte d sulfur-containing PAMAM dendrimers [Fuel 199 (2017) 91–101 and 206 (2017) 80–88] were reevaluated using deactivation kinetics model (DKM). As the result, the reaction orders newly were estimated and the calculated rate constants were quantitatively compared on both ads orbate and adsorbents.
