摘要: 以一个分子(原子)不能同时参加多个反应为出发点,在平面网格上将两个相邻格点定义为一个“超结构”.在此基础上给出一种新的元胞自动机模型,用于模拟CO在催化剂表面的氧化反应.反应只在同一个超结构内发生,并以演化几率作为参数,以控制超结构内反应物的反应过程.模拟结果表明,随着参数的不同,出现了O2中毒相、反应相及CO中毒相,与实验结果完全一致.

Abstract: Acellular automation model for the catalytic CO+O2 surface reaction is introduced by means of building oriented two pointed “suprastructure” in lattice. Reactions can only occur in the suprastructures. We use reaction probability as variable to control reactions in suprastructures. The reactions system exhibits three phases: the CO-poisoned, the O-poisoned and the reactive phase, in consistence with the Monte Carlo results.

Key words: Catalysis reaction, Cellular automation, Simulation
