Question

what is the answer of 55.20(ft3/lbmol)0.5/h to (ft3/lbmol)0.5/s? and 30.20(ft3/lbmol)0.5/h to (ft3/lbmol)0.5/s? and how can i convert them on my own?

Example 6-7 Hydrodealkylation of Mesitylene in a PFR The production of m-xylene by the hydrodealkylation of mesitylene over a Hou Detrol catalyst involves the following reactions: CH CH + CH (E6-7 + H, - VYCH CH, m-Xylene can also undergo hydrodealkylation to form toluene: CH, , - CH. + H CH, CH, . (E6-1 A significant conomic incentive The second reaction is undesirable, because m-xylene sells for a higher price to toluene (S1.32/lb vs. 50.30/1b). Thus we see that there is a significant incentive maximize the production of m-xylene. The hydrodealkylation of mesitvene is to be carried out isothermally 1500-R and 35 atm in a packed-bed reactor in which the feed is 66.7 motse hyd gen and 33.3 mol Se mesitylene. The volumetric feed rate is 476 fth and the read volume de p) is 238 it! The rate laves for reactions 1 and 2 are, respectively, tu=kGCH (E6-7 Ty=k.ca E6- where the subscripts are: M = mesitylene.
