In a small high-speed DI diesel engine, injected fuel sprays impinge on the wall of piston cavity. Discussion and analysis combustion phenomena in engine demand measurement characteristics impinging spray. experiments presented here, oil was into high pressure chamber which compressed air or CO2 gas at room temperature charged. From these results, detailed information concerning droplets density spray obtained. The effects ambient density, distance from to nozzle, injection were analyzed....
We have performed R&D project on methanol synthesis from CO2 and hydrogen in order to contribute mitigation. High-performance Cu/ZnO based multicomponent catalysts were developed. The roles of metal oxides contained Cu/ZnO-based classified into two categories: (1) Al2O3 or ZrO2 improves the dispersion copper particles catalyst; (2) Ga2O3 Cr2O3 increases activity per unit surface area catalyst. long-term stability during was improved by adding a small amount silica catalysts. Silica added...
Ethanol conversion to C3+ olefins over Fe/H-ZSM-5 catalysts was investigated. Fe is a non-toxic and cheap metal. are useful not only as fuels but also chemicals. fully effective even in the presence of water EtOH. Therefore, there no need remove from water-containing ethanol, such bio-ethanol. The initial selectivity affected by kind source calcination temperature significantly, except case iron phosphate used source, which showed low selectivity. In general, slightly decreased with...
Abstract We investigated the biofilm removal effects of laser activated irrigation (LAI) using a pig model, focusing on impact fiber tip position, and used high-speed camera to observe occurrence positioning cavitation associated with irradiation. A total 16 roots deciduous mandibular second premolars from 4 pigs were used. After pulpectomy, canals left open for 2 weeks sealed induce intraradicular biofilm. Root canal was then performed Er:YAG activation. The inserted at two different...
Abstract Methanol, together with methane, is formed for the first time by homogeneous hydrogenation of CO2 using a catalytic system consisting Ru3(CO)12 and alkaline iodides in N-methylpyrrolidone (NMP) solution at 240 °C. The course reaction indicates successive formation CO, methanol, then methane. FT-IR analysis resulting solutions reveals several species ruthenium carbonyl anion their mutual interchanges during reaction. A mechanism overall proposed, based on these results.
Hydrogen production by cellulose gasification over Ni catalysts was investigated. The catalytic activity and the species of products were affected type supports. use simple metal oxides as supports resulted in formation large quantities dark-colored tar but avoided carbon deposition, whereas zeolites inhibited promoted deposition. loading Ce on zeolite enhanced rate partially On other hand, most cases, higher reaction temperatures led to a greater quantity hydrogen being formed,...
