Hydrocarbon hydrogenation uses bifunctional catalysts as well. For the hydrogenation of ethylbenzene and 1-hexene, clinoptilolite was swapped with Ni2+ and subsequently thermally reduced. The hydrocracking of n-paraffin in a naturally occurring erionite ore that had been calcined and exchanged with NH4+ and Ni2+ was examined. A catalyst life of more than a year has been shown to be feasible in pilot plants. Bifunctional catalysts based on a component for the synthesis of methanol and synthetic zeolite may be thought of as a system with non-additive, synergistic features, regardless of the fabrication technique. It is well known that the syngas conversion process's bifunctional catalyst selectivity and activity depend on the NBAC value, which denotes the relative concentration of acidic centres in the bifunctional catalyst. The reaction of methanol conversion to DME and hydrocarbons is accelerated in proportion to the growth of the NBAC value of the bifunctional catalyst, which also has a rise in its acidic function.
