Modeling of Reactor of Straight–run Gasoline Fractions Refining on Zeolite Catalysts

Abstract

Zeolites are widely used as catalysts and catalyst supports for fuel and lubricants production processes with enhanced performance properties. Design of industrial reactor requires the construction of a mathematical model and selection of optimal operating conditions for reducing the number of scaling stages. The authors have proposed a scheme of hydrocarbons conversion on zeolite catalysts, thermodynamics of reactions has been considered and the inverse kinetic problem has been solved. The model of reactor of straight–run gasoline fractions refining in software HYSYS Aspen Plus™ process simulator has been developed and its adequacy to experimental data has been shown

Síntese e apliacação dos materiais mesoporosos do tipo MCM-41 e MCM-48 contendo metais (Ti ou Zn) em adsorção/fotocatálise do corante azul de metileno/ Synthesis and application mesoporous materials of MCM-41 an MCM-48 type containing metals (Ti or Zn) in adsorption/photocatalysis of methylene blue dye

“…Os suportes heterogeneizados são utilizados nos mais variados tipos de reações catalíticas, entre elas: hidrogenação (Fujiwara et al, 2015), oxidação (Li et al, 2016), refino (Samborskaya et al, 2015) e também em reações voltadas para a química ambiental, onde podemos destacar as reações de fotocatálise (Dávila-Jiménez et al, 2016).…”

Production of Gasoline Using Stable Gas Condensate and Zeoforming Process Products as Blending Components

“…In this work, we suggest to use zeolites for upgrading stable gas condensate via the Zeoforming process, to make it a suitable blending component for commercial gasoline production. − Zeolites are microporous aluminosilicates which are used in a variety of industrial applications due to several advantages, such as low operational costs and capital investments, simplicity of the technology (in terms of catalyst synthesis and process design), safety requirements with regards to explosion and fire hazards, and low sensitivity to the feedstock quality . Zeolites are widely used as ion exchangers , and as shape-selective heterogeneous catalysts, especially in the petroleum refining industry, hydrocracking and hydrodewaxing, linear alkyl benzene synthesis, catalytic cracking, isomerization, aromatization, , methanol to hydrocarbons conversion, and hydrodeoxygenation …”

“…In this case, due to their unique structure, molecular-sieve and acid properties, zeolites show high activity and selectivity toward reactions of dehydrogenation, isomerization, cracking, oligomerization, and dehydrocyclization of organic molecules. − In comparison to conventional reforming of gasoline fractions, Zeoforming does not require the use of hydrogen. , Another advantage is that Zeoforming is not sensitive toward catalytic poisons, such as sulfur compounds, which are always present in petroleum fractions . There are numerous works dedicated to the gasoline blending technology − and various petroleum refining processes using zeolite catalysts. − However, there is a lack of research on the use of the stable gas condensate (unprocessed and upgraded via Zeoforming) as one of the blending components of commercial gasoline.…”
