Abstract

Den foreliggende oppfinnelsen vedrører en fremgangsmåte for fremstilling av etylenoksid ved katalytisk oksidasjonsreaksjon av etylen med molekylært oksygen med rørreaktor. Reaktoren omfatter en bunt reaksjonsrør (5) som er nedsenket i et varmevekslerfluid og fylt med en fast sølvbasert katalysator (8) og som traverseres av en reaktiv gasstrøm som inneholder etylen og molekylært oksygen, som i kontakt med katalysatoren danner etylenoksid. Arealet av det indre tverrsnittet av reaksjonsrørene (5) minker mellom innløpet (1) og utløpet (3) av rørene over minst en del av lengden av rørene og forblir konstant over enhver gjenværende del. Fremgangsmåten gjør det mulig å øke selektiviteten av reaksjonen til etylenoksid for en gitt produksjon av etylenoksid. Det er også mulig å anvende en maksimal charge av aktiv katalysator pr enhet indre rørvolum tilgjengelig i reaktoren, noe som spesielt skyldes en optimal varmeveksling som er i stand til mer bestemt å levere en relativt stabil reaksjonstemperaturprofil over hele lengden av reaksjonsrørene og spesielt å forhindre ukontrollerte reaksjoner.The present invention relates to a process for the preparation of ethylene oxide by catalytic oxidation reaction of ethylene with molecular oxygen with tube reactor. The reactor comprises a bundle of reaction tubes (5) immersed in a heat exchanger fluid and filled with a solid silver-based catalyst (8) and traversed by a reactive gas stream containing ethylene and molecular oxygen which, in contact with the catalyst, forms ethylene oxide. The area of the inner cross-section of the reaction tubes (5) decreases between the inlet (1) and the outlet (3) of the tubes over at least part of the length of the tubes and remains constant over any remaining portion. The process makes it possible to increase the selectivity of the reaction to ethylene oxide for a given production of ethylene oxide. It is also possible to use a maximum charge of active catalyst per unit of internal pipe volume available in the reactor, which is due in particular to an optimal heat exchange capable of delivering a relatively stable reaction temperature profile over the entire length of the reaction tubes and in particular to prevent uncontrolled reactions.
