FUNDAMENTAL KINETIC MODELING FOR REACTOR DESIGN

AND SIMULATION

G.F. Froment

Artie Mc Ferrin Department of Chemical Engineering

Texas A & M University, Texas, USA

The necessity and the potential of a more fundamental approach to the kinetic modeling

of catalytic processes is illustrated by means of a few examples in which special attention is

given to the role of the catalyst.

The first example deals with phthalic anhydride synthesis in which the catalyst itself

provides the oxygen inserted into the reacting species.

A second example deals with solid-acid alkylation and with the conversion of methanol

into olefins on zeolites. In these processes the catalyst is progressively deactivated through

irreversible site coverage or channel blockage by heavy reaction products, but the latter are

not inert towards the reacting species and also contribute to the evolution of conversion and

selectivities.

Finally, the transformation of heavy oil fractions into more valuable and clean

transportation fuels is considered. A realistic representation of the overwhelming product

distribution of these processes requires the decomposition of the reaction scheme in terms of

elementary steps of carbocation chemistry. The fundamental modeling based upon the single

event concept, in combination with the Evans-Polanyi relationship, permits a drastic reduction

of the number of independent rate parameters, accessible through judicious experimentation.

The potential of such an approach in the simulation of the commercial hydrocracking of

vacuum gas oil is illustrated.

Abstract

The potentiality of silicate glass fiber materials modified with Zr and REM (Rare Earth Metal) oxides as a new catalysts for application in reactions of oxidative and environmental catalysis is evaluated. The questions related to study of molecular structure of glass, formation and stabilization of highly dispersed metal (mostly, Pt and Pd) species in the bulk of glassmatrix are elucidated. The glass fiber based catalysts showed high performance in number reactions (deNOx, VOC removal, selective hydrogenation of acetylene/ethylene feedstock, CH4 conversion to C2H4 via intermediate selective halogenation of methane to methylchloride, etc). The effect of heat/mass transfer on catalyst performance, the results of pilot testings, as well as the main advantages of these catalysts in comparison with traditional ones are also considered.

The silicate glass fiber materials are produced in the industry and widely used as

perfect heat and electric insulators. At the same time these materials are practically unknown to people from catalysis despite of obvious advantages such as high thermostability (up to 1200C), mechanical strength, improved hydrodynamic properties, as well as possibility to make catalytic reactors with new flexible design and to move from traditional packed catalysts beds to structural ones.

The lecture is devoted to study of glass fiber materials modified with Zr and REM (Rare Earth Metals) oxides in order to reveal their potential properties in catalysis. These materials

comprise of elemental fibers of 7 - 9 m in diameter, twisted into separate yarns of 0,2 - 1 mm in size which are used for manufacturing of different shape textiles. The glass fibers are nonporous and surface area is equal to geometrical one (ca. 1 m2/g). The average chemical composition of leached materials is a following (% wt.): 80-90 SiO2, 10% ZrO2 or REM + 0,5-3 Al2O3. By means of IRS and NMR the layered model of glass structure, when 2-3 rows of SiO4 tetrahedra are altered by hydroxyl groups, was proposed. The presence of OH-groups is important because the introduction of active metal cations via ion exchange mechanism with

protons takes place. The effective procedure for introduction of metal (mostly, Pt, Pd) complexes into the bulk of glassmatrix, their further reduction into highly dispersed metal species (clusters) or unusual low-valent states at elevated temperatures was developed and characterized by UV-Vis DRS in combination with TPO and TPR. The size of metal clusters was too small to be observed by high resolution electron microscopy. These species (up to 10 in size) appeared under heating by electron beam only, possibly due to partial sintering of smaller metal particles. Pt or Pd clusters ar
