We consider a combination of semi-Lagrangian approach and finite element method for initial boundary-value problem for the Navier-Stokes equations. To construct a numerical method, we use uniform space mesh and trilinear functions. For system of Navi

The mechanism for the formation of C2+ paraffins differs from the mechanism for the formation of methane. While methane is obtained due to hydrogenation of methyl groups, C2+ hydrocarbons are formed as the result of the conversion of alkyl intermedia

The only secondary reaction of olefins in the Fischer-Tropsch synthesis on Co/SiO2·Al(III) and Co/SiO2·Cr(III) with 2.7·10−6 and 4.0·10−6 g-ion/m2 cation concentration in the support matrix, respectively, is dimerization of ethylene to give a

It was shown that the molecular-mass distributions of hydrocarbons formed on a Co-ThO2-MgO-kieselguhr industrial catalyst at 1MPa pressure differ from those found at low pressures and are adequately described by the previous mathematical model based

Kinetic models were used to investigate the Fischer-Tropsch synthesis at increased pressures. The general mechanism proposed for the process at low and increased pressures was based on quantitative analysis of the products obtained with cobalt cataly

Increasing the working time of the catalyst led to a change in the surface concentration of various intermediates. The activity of the catalyst decreased principally as a result of the decrease in the rate of methane formation. The probability of cha

It was shown that molecular-mass distributions of hydrocarbons produced over Co/SiO2 · Fe(III), Co/SiO2 · Cr(III), and Co/SiO2 · Zn(II) catalysts are described well by a mathematical model proposed earlier for rationalizing the distribution of pro
