![]() ![]() The aim of this work was to develop dynamic simula- tion model of 1-Butene reactor operating at a site of RIL for various operational and engineering studies.1- Butene reactor was simulated in ‘UniSim Design’ si- mulation software purchased from Honeywell Interna- tional Inc.Ģ. The active species are realized by mixing TEAL and LC 2253 catalyst under ethylene pressure. The modifier and the titanium compound LC 2253 are mixed under a well-defined ratio and form the active catalyst. The poly- merization reaction is inhabited in the Alphabutol Cat- alyst by adding a modifying agent to the catalytic for- mula to stabilize the titanium (IV) complex, thus pre- venting the formation of titanium (Ill) complex which is responsible for the polymer formation. Ziegler type catalyst based on titanium has a tendency to polymerize ethy- lene to high molecular weight materials. The march in the catalytic dimerization of ethylene into 1-Butene was pioneered in 1952 by the systematic studies of Ziegler which were originally aimed at producing higher-chain polymers via the growth reaction of the organ aluminum compounds (multiple insertion of ethylene into the Al-C bonds). UNISIM DESIGN CRACK ACTIVATORTitanium based Catalyst LC2253 (Trade Name) and activator Triethyl Aluminum (TEAL) are used for selective 1-Butene production. The liquid phase catalytic dimerization of gaseous ethylene in 1-Butene stands as the most selective and economical route to produce polymerization grade 1- Butene. UNISIM DESIGN CRACK CRACKI NTRODUCTIONġ-Butene is a basic petrochemical building block of captive requirements, not only it can be converted to polybutene-1 and butylene oxides, but also its largest utilization is as a co-monomer with ethylene for the production of higher strength and higher stress crack resistance polyethylene resins (LLDPE and HDPE). Index Terms - UNISIM Simulation Kinetic model Dimerization of ethylene 1-Butene selectivity Reactor simulation 1. The simulation model is very flexible and useful for the simula- tion and operation of this type of reactor. Ow- ing to this limitation of the software, the bubble reactor had to be described by dividing reactor in five small continuous stirred types of reactor (CSTR) for optimum performance. The simulation of such a reactor was performed using the simulation program UNISIM, which does not have provision for non-standard reaction kinetic expressions. The catalyst and TEAL is added in pump around loop in optimum ratio to increase selectivity of 1-Butene. The heat of reaction is removed by heat exchanger provided in pump around loop. ![]() BY-Products are mainly hexenes formed either by reaction of 1-Butene with Ethylene or by trimerization of ethylene, and some small amount of polymer forma- tion. This dimerization is achieved thanks to a titanium compound activated by alkyl aluminum (TEAL). Other different themes covered include: structure of the active species, kinetics, mechanistic considerations and the principal reaction parameters. This paper identifies the components of this homogeneous system and dis- cusses, in fair detail, the factors controlling its selectivity to 1-Butene. ![]() The liquid phase catalytic dimerization of ethylene in 1-Butene stands as the most selective and economical route to produce polymerization grade 1-Butene.
