Thermogravimetry (TG) was used to obtain experimental data on the pyrolysis of sorghum biomass in an inert atmosphere at a heating rate of 3 K/min. Mathematical modeling of the process was carried out based on a three-component kinetic model. Accordi

The problem of a three-dimensional catalyst pellet with three characteristic sizes a, b, and c under conditions of intradiffusion resistance and a first-order reaction has been discussed. Using an exact solution in the Cartesian coordinate system, de

A catalyst grain in a fixed-bed reactor is surrounded by an non-uniform flow because the reactant concentration changes as the reaction mixture moves through the bed. A problem was considered in which a spherical grain is in an non-uniform flow with

Weekman and Gorring [2] considered the problem of the influence of the Stefan flow in a catalyst grain for mth order gas-phase chemical reaction A → nB. Special numerical methods were used to solve the problem. This paper proposes a simple method f

The main reasons of catalysts deactivation in hydro-processing pyrolysis liquids are by coke deposition, poisoning by bio-oil impurities (S, N, K, Cl, etc.), leaching of catalyst components, structural degradation in the presence of H2O, and sinterin

Mo- and Ni-containing carbide catalysts were prepared by a Pechini-based method using citric acid as a complexing agent. All the catalysts were characterized by temperature-programmed reduction, X-ray diffraction (XRD), X-ray photoelectron spectrosco
