The low-temperature oxidation of isobutane and propylene has been studied by interrupting the reaction by withdrawing the partly reacted mixture from the reaction vessel. After treatment designed to destroy peroxides the mixture was returned to the reaction vessel. The results show that the termination of the induction period is due to the accumulation of an active intermediate or intermediates in the gas phase. In both systems these intermediates are probably not alkyl hydroperoxides. �� Changes in the surface of the reaction vessel brought about by processes occurring in the early stage. of the reaction do not contribute to the termination of the induction period.

Biogas (mainly methane and carbon dioxide) produced from biomass anaerobic digestion is considered as a potential renewable gas-phase fuel. That is why the study of the mutual effects of CH4/NOx have attracted considerable attention in the past decade. In this work, the oxidation of methane with and without NOx addition has been investigated in a jet-stirred reactor.

This study investigates the potential of controlling diesel homogenous charge compression ignition (HCCI) combustion by blending ethanol, which inhibits low temperature oxidation offering the possibility to control ignition in HCCI combustion. The simulation results from a multi-zone model show that the ethanol reduces the key active intermediate radicals OH, CH2O, H2O2, delays the low temperature oxidation reaction (LTR), reduces the heat released during LTR stage. As a result, it retards the main combustion stage.

AbstractLow temperature oxidation of a Cu-base leadframe has been investigated to understand the effect of Cu oxidation on the adhesion between Cu-base leadframes (Cu L/F) and epoxy molding compounds (EMC). From the kinetic studies on the oxidation, oxide growth was found to follow the parabolic rate law in the temperature range of 150 °C to 300 °C and the activation energy for the oxidation was 17.0 kcal/mol. X-ray photoelectron spectroscopy (XPS) studies confirmed that the oxide film consisted of Cu2O, CuO, and NiO. It was shown that the early stage of oxidation improved the adhesion strength. Furthermore the optimum copper oxide thickness required for the maximum pull strength ranged between 20 nm and 30 nm. The high pull strength was presumably due to the increase of surface wettability and mechanical interlocking effects resulting from copper oxidation.
