Abstract-A series of NiO/ZnO/HZSM-5 catalysts were prepared by impregnation method with varying ZnO loading ranging from 0-2 wt% and keeping 4 wt% NiO loading constant. It was found that the ZnO/NiO modified HZSM-5 catalyst was highly active and selective towards ethanol conversion to hydrocarbons at 410 °C, WHSV = 3.5 hr -1 and pressure = 1 atm. A comparison has been done to study conversion and yield of different wt% of ZnO/NiO over HZSM-5 catalyst. The performance of catalysts was evaluated by conducting experimental run in fixed bed reactor under identical conditions. The major products of the reaction were methane, ethylene, propylene, ethylmethyl ether, toluene, ethyl benzene, xylene, isopropyl benzene, ethyl toluene, and trimethyl benzene and tetra methylbenzene.It was observed that ZnO and NiO modified HZSM-5 reduces the rate of deactivation of catalyst. It was also observed that 1.5 wt% ZnO/4 wt% NiO/ HZSM-5 catalyst was highly reactive for ethanol conversion to hydrocarbons. In addition HZ (1.5 Zn/4 Ni) modified catalyst suppressed the coke deposition without affecting product yield and conversion.Index Terms-Ethanol, HZSM-5, catalyst deactivation, doping with NiO and ZnO.

Given that ethanol can be obtained from abundant biomass resources (e.g., crops, sugarcane, cellulose, and algae), waste, and CO2, its conversion into value‐added chemicals holds promise for the sustainable production of high‐demand chemical commodities. Nonoxygenated chemicals, including light olefins, 1,3‐butadiene, aromatics, and gasoline, are some of the most important of these commodities, substantially contributing to modern lifestyles. Despite the industrial implementation of some ethanol‐to‐hydrocarbons processes, several fundamental questions and technological challenges remain unaddressed. In addition, the utilization of ethanol as an intermediate provides new opportunities for the direct valorization of CO and CO2. Herein, the recent advances in the design of ethanol conversion catalysts are summarized, providing mechanistic insights into the corresponding reactions and catalyst deactivation, and discussing the related future research directions, including the exploitation of active site proximity to achieve better synergistic effects for reactions involving ethanol.
