| 摘 要： | １引言大量的研究表明，近一个世纪以来，大气中温室气体（主要是ＣＯ２）含量的迅速增加是引起全球气候变化的一个重要因素。而且，在今后若干年内，随着人类从矿物燃料中获取能源的进一步增加，ＣＯ２的排放量亦将持续增长。其中煤的利用量及在燃烧过程中ＣＯ２的排放量...

| Abstract: | The combustion rate of carbon particle in CO2/O2 as well as in air atmospheres aretheoretically studied. The chemical reactions considered include the surface C-O2 and C-CO2reactions and the gas-phase CO-O2 reaction. At the selected chemical kinetic parameters, thepredicted result shows: at ambient gas temperature between 1000 and 1700 K. The overallcombustion rate of carbon particle in CO2/O2 (CO2/O2 mole ratios is 79/21) atmosphereis lower than in air. With reducing of the CO2/O2 mole ratios, the overall combustion rateincrease obviously. |
