benzothiophene could be converted to ethylbenzene by a hydrodesulfurization reaction. Before you commit the time and money to design a reactor for this reaction, you may want to attempt to verify that the production of ethylbenzene is economically feasible. In other words, are the products worth more than the reactants and energy required to make them? If you discover the answer is no, you may have saved thousands of dollars in design fees.
(a) Reactor (Plug Flow, Mixed Flow, Packed Bed, Fluidized Bed, etc.) (b) Adiabatic vs. Isothermal reactor operation
(c) Reactor temperatures and pressures
(d) Feed ratio of hydrogen to benzothiophene
(e) Effluent conditions and compositions
(f) Weight of catalyst required
(g) Material of construction for the reactor (Hint: Is the material susceptible to accelerated corrosion due to the presence of sulfur or hydrogen?)
(h) Reactor shape and dimensions
(i) Reactor wall thickness
