Book excerpt: Results of an experimental study of the catalytic ignition of lean propane-air mixtures on platinum in a stacked-plate catalytic combustor are presented. The effects of inlet temperature, equivalence ratio and gas velocity on the ignition transient were investigated. The ignition process was characterized in terms of the substrate axial temperature profile and the exhaust gas CO and CO2 concentrations measured as a function of time after the fuel was turned on. Ignition was always found to occur first near the leading edge of the catalyst as indicated by the more rapid heat-up of the front end of the catalyst. The downstream end of the catalyst heated up more slowly and was strongly dependent on convective heat transfer from the front of the catalyst. Increased inlet temperature, equivalence ratio and velocity were all found to shorten the ignition transient and to lead to increased steady state peak substrate temperatures. increased velocity also caused the peak substrate temperature to move further toward the back of the catalyst. For the conditions studied, the initial ignition rate was found to be surface reaction rate controlled at higher velocities (above 2 m/s) but at lower velocities (below 2 m/s) the initial ignition rate was found to depend both on the surface reaction rate and the mass transport rate. The transient ignition measurements also clearly revealed the fact that complete conversion can be achieved by substrate temperatures which are several hundred degrees below steady state. Keywords: Catalytic combustion, Catalytic ignition, and Premixed turbulent combustion.

Download or read book High Temperature Catalytically Assisted Combustion written by C. Bruno and published by . This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of catalytic combustion of lean mixtures of propane/air at atmospheric pressure over platinum/alumina/cordierite catalysts were carried out over a broad range of equivalence ratios and flow velocities. Substrate (honeycomb) temperatures, chemical species at the catalyst were measured. A substantial data base for catalytic oxidation C3H8 over platinum catalysts was obtained. A two-dimensional model of the gas-phase oxidation of propane was developed. When the experimental wall temperature is used as the boundary condition for the gas-phase reactions; emissions predicted from the model agree well with measured values. From comparison with the experimental data, indications are that propane oxidation takes place via a three-step kinetic mechanism. Also from study of the relative importance of gas-phase vs. surface oxidation, conclusions are that most of the propane is burnt in the gas-phase rather than at the catalytic wall and that the wall kinetics is slower than the gas diffusion transplant.

Available in PDF, EPUB and Kindle. Book excerpt: This book follows the 2002 edition of Catalysis by Ceria and Related Materials, which was the first book entirely devoted to ceria and its catalytic properties. In the ten years since the first edition a massive amount of work has been carried out in the field, and ceria has gained a prominent position in catalysis as one of the most valuable material for several applications. This second edition covers fundamental and applied aspects of the latest advances in ceria-based materials with a special focus on structural, redox and catalytic features. Special emphasis is given to nano-engineered and nano-shaped systems which are a key factor in the predictive and rational design of ceria with novel properties.In addition, the book presents recent advances in emerging and traditional large-scale applications of ceria in catalysis, such as the treatment of emissions from mobile sources (including diesel and gasoline engines). The primary readership includes catalysis and material science researchers from academy and industry and postdoctorate and graduate students in chemistry, chemical engineering and physics.
