Feng, Fuxiang; Niu, Xiaopo; Wang, Li; Zhang, Xiangwen; Wang, Qingfa published the article 《TEOS-modified Ni/ZSM-5 nanosheet catalysts for hydroconversion of oleic acid to high-performance aviation fuel: Effect of acid spatial distribution》. Keywords: tetraethoxysilane nickel ZSM5 nanosheet catalyst; hydroconversion oleic acid aviation fuel spatial distribution.They researched the compound: N1,N1,N6,N6-Tetramethylhexane-1,6-diamine( cas:111-18-2 ).Safety of N1,N1,N6,N6-Tetramethylhexane-1,6-diamine. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:111-18-2) here.
Ni/ZSM-5 nanosheet catalysts with different Si/Al ratios were modified by chem. liquid deposition (CLD) of tetraethoxysilane (TEOS) to tailor their acid spatial distribution. Their catalytic performance was evaluated with the hydroconversion of oleic acid to aviation-fuel-range-alkanes (AFRAs) at different reaction temperatures and H pressures. The modified catalysts inherit the nanosheet structure with decreased external Bronsted acid concentration, especially the strong one. External Bronsted acid sites mainly favor the cracking of the deoxygenated products (C17/C18). Internal Bronsted acid sites mainly enhance the isomerization of the linear AFRAs. The catalytic activity of the external Bronsted acid sites was more sensitive to reaction temperature than that of the internal ones. The deoxygenation and cracking reactions were also more sensitive to H pressure compared to the isomerization reaction. High AFRA selectivity of 51.4% as well as high iso/n-alkanes ratio of 1.7 were achieved at 250° and 10 bar over NS200(1).
