Nitrobenzene is a compound derived from benzene and quite fundamental in the petrochemical industry. One of which is in the manufacture of aniline. Aniline has an important role as dyes, synthetic rubber materials, rocket fuels and pharmaceuticals. Nitrobenzene can be synthesized by the nitration reaction of benzene. The purpose of the research is to design synthesis process of nitrobenzene by using Aspen Hysys simulator. The effect of changes in operating condition on nitrobenzene will be investigated. The benefits of the research are to obtain the optimum operating temperature for nitrobenzene production so that the use of utility can be minimized.

“…This is characteristic of typical ordered mesoporous material that possesses a narrow pore size distribution of cylindrical pores. 31 The shape of the hysteresis loop and the type of isotherm of the supported catalysts are not significantly different from their corresponding supports, which indicates that the pore structure of the supports can remain unchanged after impregnating the metal components.…”

“…The Pt/Al-KIT-6, Pt/KIT-6 and Pt/HPBK catalysts and their corresponding supports exhibit a sharp hysteresis loop within the p / p 0 range of 0.6–0.8, which is a typical type IV isotherm with a H1-type hysteresis loop. This is characteristic of typical ordered mesoporous material that possesses a narrow pore size distribution of cylindrical pores …”

A Beta-KIT-6 (BK) micro-mesoporous composite material was assembled using zeolite Beta seed solution as raw material. BK composite contained both zeolite Beta units and three-dimensional cubic Ia3d mesostructure of KIT-6, which served as a catalyst support for hydroisomerization of n-heptane. The composite was characterized by a variety of techniques. Results show that catalyst Pt/HBK using the composite as the support exhibited the highest isoheptanes yield among all catalysts, which is attributed to both appropriate surface acidity and excellent mass transfer properties of Beta-KIT-6 composite. Experimental results verified that the indexed isomerization factor as a general performance descriptor could accurately predict the hydroisomerization performance of support materials.

“…The author explained that the incorporation of calcium in the framework of silicate results in weak acidity that has the effect of reducing strong acidic sites, which enhances catalytic performance [56]. A report [57] also addressed the direct synthesis of zeolite-b, Other products including benzene, cracking products and trace amount of trialkyl benzene.…”

“…The superior activity evident on ZBS-15 ( Table 2) was explained based on the strong acidity derived from walls having a zeolite-b unit and larger mesopores that provide a diffusion-free environment [57]. The activity of the catalyst ZBS-15 was maintained even after four recycles.…”
