✦ Synopsis

The NO-CO reaction on a catalytic surface is studied with the aid of the cellular automaton model of Chopard and Droz. Proper stoichiometry is taken into account in an appropriate way. A mean-field analysis of this model is given, with the results indicating that a first-order kinetic phase transition from the CO *-N* poisoned phase to the reactive phase always occurs, so that a steady reactive phase necessarily exists, independent of the type of lattice. The conclusion that for the NO-CO surface reaction the square lattice cannot support a steady reactive phase seems to be a finite size effect.

Cellular automata (CA) rules for a model surface reaction with Eley-Rideal step (exemplifying CO oxidation) have been formulated. The CA simulations corroborate the earlier known Monte Carlo (MC) simulation results and show qualitative and near quantitative resemblance. The results are analyzed and

A new approach to on-line oxygen isotope analysis has been developed which utilises existing elemental analyser and mass spectrometry technology to produce a sample of carbon dioxide gas for oxygen isotople analysis. The method relies on on-line high temperature pyrolysis of the sample over a carbon
