Продемонстрировано влияние концентрации катализатора, температуры, давления этилена на кинетический профиль кривых зависимостей скорости реакции от времени. Предложена обобщенная схема процесса тримеризации этилена в гексен-1. Вместе с тем, показана недостаточность кинетических данных по образованию продуктов реакции для полного описания процесса тримеризации в рамках единой кинетической модели, связанная с многостадийностью процесса, экспериментальным установлением зависимости каждой из стадий (образование каталитических интермедиатов, инициирование, протекание побочных реакций с участием компонентов каталитической системы, реакций три-, олиго- и полимеризации) и, таким образом, переменчивостью каталитического поведения системы.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents the results of the study of trimerization of ethylene to hexene-1 on chromium-pyrrole catalytic system in both semi-periodic and continuous processes under different reaction conditions. The influence of catalyst concentration, temperature and ethylene pressure on the kinetic profiles of have been studied. A comprehensive scheme describing the formation of all observed reaction products has been proposed. It has been concluded that all observed experimental results cannot be described within the framework of one, single kinetic model. This is due to the multistage nature of the process and the need of experimentally determination of the dependences of each stage on reaction parameters, including the stages of formation of catalytic intermediates, initiation, side reactions involving components of the catalytic system, and tri-, oligo-, and polymerization reactions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гексен-1</kwd><kwd>тримеризация этилена</kwd><kwd>хром-пиррольная каталитическая система</kwd><kwd>непрерывный режим</kwd><kwd>полупериодический режим</kwd><kwd>кинетика процесса</kwd><kwd>влияние условий реакции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hexene-1</kwd><kwd>ethylene trimerization</kwd><kwd>chromium-pyrrole catalytic system</kwd><kwd>continuous mode</kwd><kwd>semi-periodic mode</kwd><kwd>kinetics</kwd><kwd>reaction conditions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Lappin G.R., Nemec L.H., Sauer J.D., Wagner J.D., Higher Olefins.
