✦ Synopsis

Ahstraet-The sensmvlty of the relanonshlp between catalyst effectiveness m So2 ox&&on and the Thtele parameter to (1) the kmetic expression watt-respect to the presence or absence of strong SOa tibltlon, (2) the acbvatton energy m the range of 16-32 kcal/g mol. f9 the converslon of SOZ up to m. (4) the temperature at the extenor surface of the pellet m the range of 450-6OOT. and (5) the feed composltlon ran~urg from 6-K)% SO2 m m, was mvestlgated A nomsothermal model was used and the calculations were carried close to eqtuhbnum Far from eqtuhbnum, the relationship IS essentially unaffected except by converslon at the pellet surface for the case of strong product mhibllon Close to equlllbnum, the relationship IS s~gmlicantly mfluenced by conversion. temperature, and the mlet composlhon but the form of the kmetics 1s not unportant The acttvabon energy IS not a slgmficant vanable Catalyst size, surface area, and density were not spectfied while It was necessary to Ex the ratios of the transport propeties for the calculations The propertles of the American Cyanamid V~OS catalyst were used for this purpose INTRODUCIlON
