1,4-Dimethylbenzene Production from Naphtha via Catalytic Reforming

This report presents a detailed cost analysis of 1,4-Dimethylbenzene production from naphtha via catalytic reforming. In this process, catalytic reforming of naphtha produces a mixture of aromatic hydrocarbons. This mixture then undergoes a series of steps, including distillation to separate the components, adsorption or crystallization to isolate specific isomers, and other subsequent reaction processes. These reaction processes involve isomerization, which converts m-xylene and o-xylene into p-xylene using zeolite catalysts, transalkylation, which reacts xylene with itself or with trimethylbenzene to shift the isomer distribution towards p-xylene, and methylation, which adds methyl groups to toluene or benzene to form xylenes, including p-xylene. These steps culminate in the formation of 1,4-dimethylbenzene (p-xylene).
