The photocatalytic process using semiconductors with a nanostructure is one of the technologies usedfor the destructive oxidation of organic compounds such as surfactants. In this paper, thephotocatalytic degradation of Cetyl pyridinium chloride (CPC), was investigated in aqueous phaseusing various semiconductors such as titanium dioxide (Ti02), zinc oxide (ZnO), stannic oxide(Sn02). The degrad...

In this work, kinetics and thermodynamics of esterification reaction were studied.

Currently, Euro 5 (no more than 10 ppm sulfur content) and 6 (less diesel motor fuels are produced worldwide. High-quality by removing compounds using a hydrodesulfurization process. This article is devoted to the study of fuel containing 120 in presence an Al-Ni-Mo-O catalyst with 98% purification rate. According Langmuir–Hinshelwood–Panchenkov theory, kinetic model process developed calculati...

The extensive demand for cleaner environment is forcing the chemical industry to use less hazardous materials. In this regard, solid catalysts have lately attracted the attention of scientists and researchers around the world.1–8 By using sufficient amounts of these heterogeneous catalysts, their catalytic activity for ester formation can be equivalent to that of conventional homogeneous cataly...

Piranha solution is a highly acidic mixture of sulfuric acid and hydrogen peroxide. The present study aimed at developing dimensionally stable anode (DSA), made titanium metal foil coated with Ruthenium Dioxide (RuO2), for the electrochemical oxidation peroxide in presence strong under ambient conditions. Results showed that piranha was fully degraded 5 h constant current 2 A (or density 0.32 A...

The kinetics of the photocatalytic degradation of 2-naphthol has been investigated in aqueous suspensions of titanium dioxide (TiO2) under a variety of conditions, which is essential from application point of view. The degradation was studied using different parameters such as types of TiO2, catalyst concentration, substrate concentration, reaction pH and in the presence of different electron a...

Various types of carbon-based and non-carbon-based catalyst supports for nitric oxide (NO) removal through selective catalytic reduction (SCR) with ammonia are examined in this review. A number of carbon-based materials, such as carbon nanotubes (CNTs), activated carbon (AC), and graphene (GR) and non-carbon-based materials, such as Zeolite Socony Mobil-5 (ZSM-5), TiO2, and Al2O3 supported mate...

The kinetics of the simultaneous syntheses ethyl tert-butyl ether (ETBE) and butyl (BTBE) over Amberlyst™ 35 (A35) has been studied at 315–353 K in liquid phase. Different kinetic modeling approaches—namely, empirical power-law modeling, mechanistic based on Langmuir-Hinshelwood-Hougen-Watson (LHHW) Eley-Rideal (ER) formalisms, information-based modeling—have compared. Empirical equations yield...
