Five equilibrium fluidized catalytic cracking (FCC) catalysts of different types, with unit-cell sizes in the range of 24.23-24.29 Å, were evaluated in the conversion of three commercial vacuum gas oil (VGO) feedstocks in ...

In this work we present results of the first Townsend coefficient (alpha) in pure isobutane by measuring the current growth as a function of the electric field strength in a pulsed irradiation regime. A Resistive Plate ...

The regeneration of Y-zeolite catalysts used during the isobutane alkylation reaction is studied. Coke is characterized by temperature-programmed techniques and measuring the H/C ratio. The coke deposited under supercritical ...

The superficial properties of different Pt/γ-Al2O3 catalysts, modified by the addition of tin and/or lithium, were studied by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy, BET, and 2-propanol ...

The isobutane alkylation with butenes is a reaction in which the substitution of mineral acids, such as sulphuric and hydrofluoric acids, by solid acid catalysts is highly desirable. Solid catalysts with good activity and ...

The activity, selectivity, stability, and regeneration of metal-containing zeolites, used in the isobutane alkylation with C4 olefins is studied. Platinum and palladium were impregnated on Y-zeolite catalysts that were ...

An experimental study of the solubility and of the thermodynamic properties of solvation, between temperatures (303 and 343) K and at pressures close to atmospheric, of 2-methylpropane (isobutane) in several ionic liquids ...

Acid and superacid solids were evaluated in n-butane isomerization to produce isobutane. The combined dealumination and sulfatation of the starting Hmordenite zeolite improves the activity and selectivity of the catalyst.
