Abstract
The invention relates to a feed vaporization and introduction system for an OTO reactor. The invention includes: means for vaporizing at least a portion of the feed; means for contacting the at least partially vaporized feed with a first catalyst comprising one or more metals from Groups 2, 3, and 4 of the Periodic Table and/or one or more metals in the Lanthanide and Actinide series.
Claims25
A method for forming olefins from an oxygenate-containing feedstock, comprising:
- contacting the feedstock with a first catalyst upstream of an OTO reactor, the first catalyst comprising one or more metals from Groups 2, 3, and 4 of the Periodic Table and/or one or more metals in the Lanthanide and Actinide series;
- and then contacting the feedstock in the OTO reactor with a second catalyst under conditions effective to form an effluent comprising the olefins.
In a process for producing olefins from an oxygenate-containing feedstock comprising contacting the feedstock in an OTO reactor with an OTO catalyst under conditions effective to form an effluent comprising the olefins, the improvement comprising:
- contacting the feedstock upstream of the OTO reactor with a metal-containing catalyst comprising one or more metals from Groups 2, 3, and 4 of the Periodic Table and/or one or more metals in the Lanthanide and Actinide series.
A feed vaporization and introduction system for an OTO reactor, comprising:
- means for vaporizing at least a portion of the feed;
- means for contacting the at least partially vaporized feed with a first catalyst comprising one or more metals from Groups 2, 3, and 4 of the Periodic Table;
- and feed introduction means downstream of the contacting means, the feed introduction means comprising a first generally tubular member having a first end for receiving the at least partially vaporized feed, a second end adjacent to the OTO reactor, and an inner surface forming a conduit for delivering the feed from the first end to the second end and into the OTO reactor.
