Title
(EN) METHOD AND REACTOR SYSTEM FOR CONVERTING OXYGENATE CONTAMINANTS FROM AN OXYGENATE TO OLEFIN REACTOR SYSTEM TO HYDROCARBONS
(FR) PROCEDE ET SYSTEME REACTEUR DE CONVERSION DE CONTAMINANTS D'OXYGENATE A PARTIR D'UN OXYGENATE VERS UN SYSTEME REACTEUR D'OLEFINES EN HYDROCARBURES
Abstract
(EN)
Disclosed is a method and reactor system for converting oxygenate and/or olefin contaminants in a methanol to olefin reactor system product effluent to hydrocarbons, including paraffin compounds, preferably over a sulphided catalyst of the type Nickel or Cobalt combined with Molybdenum or Tungsten. In one embodiment, the oxygenate-containing stream to be hydrogenated comprises one or more of the following streams, alone or in combination: a quench tower bottoms stream, a water absorption unit bottoms stream, a C4+ stream, and/or a C5+ stream.
(FR)
L'invention concerne un procédé et un système réacteur de conversion de contaminants d'oxygénates et/ou d'oléfines dans un méthanol vers l'effluent du système réacteur d'oléfines en hydrocarbures, y compris les composés de paraffine, de préférence dans un catalyseur sulfuré du type nickel ou cobalt combiné à du molybdène ou tungstène. Dans un mode de réalisation, le courant contenant l'oxygénate devant être hydrogéné comprend un ou plusieurs des courants suivants, séparés ou combinés : un courant de fond d'une tour de trempe, un courant de fond d'une unité d'absorption d'eau, un courant C4+ et/ou un courant C5+.
