Production of aromatics from heavier n-paraffins on hybrid cracking-reforming catalyst
Autor: Koji Sakashita, Toshiyuki Kimura, Sachio Asaoka, Narihito Hata
Publikováno v: Catalysis Today. 185:119-125
Selective production of aromatics from the heavier n-paraffins was studied on nano-structured (ns) catalysts consisting of ns alumina and MFI-type H-galloaluminosilicate (H-GaAlMFI) zeolite. Performance of the hybrid H-GaAlMFI zeolite catalyst with n

Catalyst of Palladium Supported on H-Beta Zeolite with Nanosized Al2O3 for Isomerization of n-Heptane
Autor: Chie Suezaki, Toshiyuki Kimura, Sachio Asaoka, Xiaohong Li, Koji Sakashita
Publikováno v: Journal of the Japan Petroleum Institute. 55:99-107
Synthesis isoparaffins from light naphtha was studied using n-hexane conversion. The main target products were multi-branched isoparaffins. Which are harder to form than mono-branched isoparaffins in the zeolitic pores. Nano-technology was applied to

Catalytic Roles of Nano-Sized Oxides Composed with Zeolite for Hydrocracking, Catalytic Cracking and Reforming
Autor: Koji Sakashita, Toshiyuki Kimura, Xiaohong Li, Sachio Asaoka
Publikováno v: Catalysis Surveys from Asia. 15:259-266
Nano-sized oxides, especially alumina hold catalytic roles by composed with zeolite for resid catalytic cracking, low pressure deep desulfurization, isoparaffin production through hydrocracking, and naphtha reforming to isoparaffins. Selective co-pro
