Carbon monoxide differential sensitivity

In Table A.l, the obtrusive difference between carbon monoxide and hydrogen is the zero response of the carbon monoxide logjo f to pressure, in contrast to the significant response of hydrogen, for which logigl, the electrical output AG, and each decline with pressure. The same pressure sensitivity differentiates hydrogen fuel in the next section. 

For example, by examining the initial and differential heats of adsorption measured on Pt/Al203 powders calcined at different temperatures, Uner and Uner [50] concluded that CO adsorption processes is not structure-sensitive. CO heats of adsorption values obtained by the authors are plotted against carbon monoxide coverage in Fig. 12.4. The heat of adsorption data for all catalysts fell on the same curve.
