Hydrogen decoking with

Decoking with Hydrogen. Hydrogen was found to be effective, but relatively slow in removing coke formed by carbon monoxide disproportionation. Hydrogen reacted with coke as follows ... [Pg.287]

Cases where a solid directly participates in an overall reaction include the burning of solid fuels, the decoking of cracking catalyst, the reduction of iron ore with hydrogen, and the purification of water in an ion exchange bed. A unifying aspect of all these examples is that the solid participates directly, appears in the reaction stoichiometry, and will ultimately be consumed or exhausted. Often the size and shape of the... [Pg.421]

Figure 4. Relative metallic or acidic activity as a function of relative residual carbon content on the "burned1 catalyst. The unity of catalytic activity is the percentage of cyclohexane produced by hydrogenation of benzene (a), or i-pentane produced by n pentane isomerization (b), over the completely decoked catalyst. The unity of residual carbon is the percentage of carbon in the initial catalyst (Table 1). I, catalyst I burnt with ozone-air II, catalyst II burnt with 02-N2 III, catalyst III burnt with 02-N2.
