Effects of Steaming and SiO2 Surface Passivation on SSZ-13 Zeolites in the Ethylene to Propylene Reaction

Autor: Chul-Ung Kim, Sungjune Lee, Nanah Kim, Kwang-Eun Jeong, Joo-Wan Kim, Tae-Wan Kim, Soon-Young Jeong

Publikováno v: Journal of Nanoscience and Nanotechnology. 20:5783-5786

SSZ-13 zeolite was modified by two kinds of post-treatment methods such as steaming and SiO2 surface passivation (silylation) for ETP catalyst with high activity. The former steaming treatment was conducted in the range of 400–700 °C, whereas the

Effect of silica supports on deoxygenation of methyl palmitate over mesoporous silica-supported Ni/Al catalysts

Autor: Tae-Wan Kim, Chul-Ung Kim, Su-Un Lee, Jeong-Rang Kim, Eun Sang Kim, Sungjune Lee, Kwang-Eun Jeong

Publikováno v: Journal of Industrial and Engineering Chemistry. 83:366-374

To develop an efficient catalyst for deoxygenation (DO) as the first step in biojet fuel production with silica-supported Ni/Al catalysts, the effects of silica supports were investigated in terms of pore structure, acidity, and pore size. The pore s

Cobalt-isomorphous substituted SAPO-34 via milling and recrystallization for enhanced catalytic lifetime toward methanol-to-olefin reaction

Autor: Soon-Yong Jeong, You-Jin Lee, Kwang-Eun Jeong, Jeong-Rang Kim, Su-Un Lee

Publikováno v: Journal of Industrial and Engineering Chemistry. 79:443-451

Silicoaluminophsophate (SAPO)-34 is considered as a promising catalyst for methanol-to-olefin (MTO) reaction, because its cylinder-like cages with small 8-ring pore openings restrict the diffusion of large hydrocarbons and exceptionally give high sel

Role of Au-TiO2 interfacial sites in enhancing the electrocatalytic glycerol oxidation performance

Autor: Hyung Ju Kim, Kwan Young Lee, Kwang Eun Jeong, Young-Min Kim, Ho Jeong Chae, David H. K. Jackson, Jisu Han

Publikováno v: Electrochemistry Communications, Vol 96, Iss, Pp 16-21 (2018)

In this work, we present an efficient catalyst design strategy using an atomic layer deposition (ALD) method that allows atomic level surface control of the Au catalyst, enhancing the electrochemical glycerol oxidation performance. Using ALD, a thin

Ring Opening of Naphthenic Molecules Over Metal Containing Mesoporous Y Zeolite Catalyst

Autor: Tae-Wan Kim, Chul Ung Kim, Kwang Eun Jeong, Soon Yong Jeong, Eun Sang Kim, Chang Ha Lee, You Jin Lee

Publikováno v: Journal of Nanoscience and Nanotechnology. 15:5334-5337

Mesoporous Y zeolite (Meso-Y) with a uniform mesopore was synthesized via pseudomorphic syn- thesis. The Meso-Y supported Ni-W catalyst (NiW/Meso-Y) was introduced as a catalyst for the selective ring opening of naphthenic rings. The catalytic test f
