Shuichi Niwa,Muthusamy Eswaramoorthy,Jalajakumari Nair,Anuj Raj,Naotsugu Itoh,Hiroshi Shoji,Takemi Namba,Fujio Mizukami +7 more
TL;DR: An efficient process using a shell-and-tube reactor, in which a gaseous mixture of benzene and oxygen is fed into a porous alumina tube coated with a palladium thin layer, attained phenol formation selectivities of 80 to 97% at benzene conversions of 2 to 16% below 250°C.
Journal ArticleDOI
A membrane reactor using palladium
TL;DR: In this paper, the cyclohexane deshydrogenation in benzene and hydrogene is reversible, and a membrane de palladium is used to separer l'hydrogene au fur and a mesure de sa formation.
Journal ArticleDOI
Development of tubular substrates, silica based membranes and membrane modules for hydrogen separation at high temperature
TL;DR: In this article, a tubular alpha alumina substrate with 0.7μm pore size and 40% porosity was used as the membrane substrate and an intermediate alpha alumina layer was formed by dip-coating over the substrate.
Journal ArticleDOI
Hydrogen production from the gasification of lignin with nickel catalysts in supercritical water
Takeshi Furusawa,Takafumi Sato,Hirokazu Sugito,Yasutomo Miura,Yasuyoshi Ishiyama,Masahide Sato,Naotsugu Itoh,Noboru Suzuki +7 more
TL;DR: In this paper, the results of characterization for reduced Ni/MgO catalysts showed that Ni metal and NiO-mgO phase are formed after the reduction of calcined catalyst by H2 and Ni metal surface area decreased with increase in calcination temperatures.
Journal ArticleDOI
All electron scalar relativistic calculations on adsorption of CO on Pt(1 1 1) with full-geometry optimization: a correct estimation for CO site-preference
TL;DR: In this article, the authors show that all electron scalar relativistic (AER) calculations are essential to obtain the correct site-preference, atop followed by bridge and then hollow (fcc and hcp).
