In industrial scale of Gas to Liquid (GTL) process in Fischer-Tropsch (FT) synthesis, a part of reactor outlet gases such as CO2 and CH4 as side reaction products, is usually recycled. In this study, the influence of CO2 and CH4 on the performance and selectivity of Co-Ru/Al2O3 catalyst is investigated by injection of these gases (0-20 vol. % of feed) to the feed stream. The effect of temperatu...

Abstract CO 2 single-gas permeance has been studied in the present work by ssz-13 membrane. SEM was used to characterize membranes. Feed flow rate, pressure, Sweep gas rate as parameters, and these factors varied at five levels with an orthogonal array of L 25 . Applying Taguchi experimental design allowed examine impact most important parameters on membrane permeabilit. had biggest effect feed...

Abstract: Two experiments were conducted to evaluate the effects of feed bin design and the use of passive agitators on flowability of feed containing 40% dried distiller...

Toluene diamine (TDA) is a main carcinogenic aromatic pollutant in some industrial wastewater. In this study, the reverse osmosis with DSS-HR98PP as the membrane was employed for the removal of TDA in an aqueous environment. The Box–Behnken Design (BBD) of the experimentwas used to consider the effect of operational variables such as pressure, pH and the feed volu...

this study was carried out to determine the effects of immunogen as a prebiotic on growth-related parameters and gut micro-flora in r. kutum fry. a basal diet was formulated using common feed ingredients supplemented with immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets.  fish were randomly distributed in 500 l fiberglass tanks (1×1×0.5 m). the experiment lasted for eight ...

Steam reforming integrated with oxidation of methanol was considered with numerical simulation. The parallel micro-channels with circular cross sections were used. Because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. Hence, the approximation of a cylindrical channel is appropriate. Effect of this changing in cross section was considered and results ...

A mathematical model is derived to simulate the performance of spiral wound membrane modules for the pervaporative separation of binary liquid mixtures. Permeation through the polymer membrane is described by a detailed solution–diffusion model. Flory–Huggins theory is used to predict solubility of the penetrants, while the composition and temperature dependence of the diffusion coefficients ar...

Fatty acid esterification is increasingly realized as a reactive distillation (RD) process because of its formation being affected by the chemical equilibrium. The reactive distillation column performance for the production of isopropyl palmitate by esterification of the palmitic acid with isopropanol has been studied in the present research. The reaction was catalyzed in the presence of zinc a...
