In order to investigate the effect of operating variabls on the yield of aromatics,a certain fraction of a straight run gasoline containing 48.4% (wt.)naphthenes was catalytically converted into aromatics over a bed of 100 ml 14—20 mesh,granular,platforming catalyst under various opera- ting conditions.The ranges of these investigations were:temperature 430— 510℃,pressure 20—50 atm.,WHSV 1.58—6.32 and hydrogen-oil molar ratio 4:1—10:1.The single pass fresh hydrogen process was adopted. The result of data treatment implied that the following second-order reaction rate expression correlates the aromatics production rate r with the operating variables satisfactorily. r=r_0(1-bx)~2, where x=aromatics yield based on feed(wt.%),and r_0 and b are constants. Superfacially r_0 may be regarded as the reaction rate constant,whereas b as a stochiometric coefficient of the equivalent kinetic equation.Both are functions of the operating temperature,pressure and hydrogen-oil molar ratio. For 4:1 hydrogen-oil molar ratio,which seems to be one of the most promising operating conditions,the differential and integral forms of the rate equation for aromatics yield are as follows: The apparent activation energy of the aromatics yield reaction by platforming under the conditions investigated,therefore,equals to 33,500 cal/gm-mol.The values of b at isobaric conditions may be correlated as: In b_(50)=8200/RT-17.5/R The significance of b is discussed thermodynamically. Considerable variations,though not large,in aromatic yield were observed when the hydrogen-oil molar ratio changed from 4:1 to 10:1.For example,at 30 atm.,490℃,this effect may be expressed by r=(p/186p+144)×10~5(1-bx)~2, where p=partial pressure of the feed stock,atm. Besides,the relative initial rates of C_8 aromatics,toluene and benzene formation were found to be in the increasing order of their molecular weights.Thus under certain operating conditions the initial rate of C~8 aromatics formation was 2.5 times that of the toluene initial formation rate,and 20 times that of the benzene formation rate.
