Promotion and inhibition by hydrogen sulfide of thiophene hydrodesulfurisation over a sulfide catalyst
Abstract
The reaction of thiophene has been studied between 300 and 400 °C and 0.1 MPa over a sulfided CoMo–Al2O3 catalyst with various amounts of H2S; besides the usual inhibiting effect, it has been found that low levels of H2S promoted the reaction above 380 °C.
