S.A. Shahamiri,I. Wierzba +1 more
TL;DR: In this paper, the combustion of preheated lean homogeneous mixtures of hydrogen with methane in air in a catalytic packed-bed reactor was modeled at atmospheric pressure, and it was shown that the hydrogen is consumed completely within the early part of the reactor length in all the cases considered for simulations.

A model of elementary chemistry and fluid mechanics in the combustion of hydrogen on platinum surfaces
TL;DR: In this paper, the catalyzed combustion of lean hydrogen-oxygen mixtures in a stagnation flow over a platinum surface and in a flat-plate boundary layer is analyzed. But the results of the analysis are limited.

Experimental and numerical investigation of the catalytic ignition of mixtures of hydrogen and oxygen on platinum
TL;DR: In this paper, the authors studied catalytic ignition of mixtures of H2 + O2 by measuring and simulating the temporal evolution from the kinetically controlled regime (i.e., prior to ignition) to the state controlled by mass transport after ignition.
