B15 A packed bed micro reactor (V = 0.31 cm3, W = 25 mg) is tested with the hydrosulfurization of a feed mixture of 0.066 wt% dibenzothiophene in a carrier liquid of n-hexadecane. This feed at 104 atm and 300 C is passed at various flow rates over the catalyst, reaction is first order and the following results are obtained I', kg hr/m3 6.8 10.4 14.0 20.4 0.45 0.59 0.70 0.83 Find whether the flow pattern in this reactor is closer to mixed flow of plug flow, and then calculate the rate constant for this reaction.
