Abstract
Ionic liquid catalyzed hydrocarbon conversion processes for upgrading oxygenate containing olefinic hydrocarbon feedstocks may involve treating an oxygenate containing hydrocarbon stream to provide an olefin enriched hydrocarbon stream, which may be contacted with an ionic liquid catalyst under hydrocarbon conversion conditions to provide a converted hydrocarbon stream containing one or more halogenated components; such components may be removed from the converted hydrocarbon stream to provide one or more dechlorinated hydrocarbon products.
Claims21
An ionic liquid catalyzed hydrocarbon conversion process, comprising:
- a) treating an oxygenate containing hydrocarbon stream in an olefin enrichment zone under olefin enrichment conditions to provide an olefin enriched hydrocarbon stream comprising olefins;
- b) contacting the olefin enriched hydrocarbon stream with an ionic liquid catalyst in a hydrocarbon conversion zone under hydrocarbon conversion conditions to provide a converted hydrocarbon stream comprising one or more halogenated components;
- and
- c) removing the halogenated components from the converted hydrocarbon stream to provide a dechlorinated hydrocarbon product.
An ionic liquid catalyzed hydrocarbon conversion process, comprising:
- a) contacting an oxygenate containing hydrocarbon stream with a dehydration catalyst in a dehydration zone under dehydration conditions to provide an olefin enriched hydrocarbon stream;
- b) contacting the olefin enriched hydrocarbon stream with an ionic liquid catalyst in an alkylation zone under alkylation conditions to provide an alkylate product comprising one or more halogenated components;
- and
- c) contacting the alkylate product with a hydrodechlorination catalyst in the presence of hydrogen in a hydrodechlorination zone under hydrodechlorination conditions to provide a dechlorinated alkylate product.
An ionic liquid catalyzed hydrocarbon conversion process, comprising:
- a) contacting an oxygenate containing hydrocarbon stream with a dehydration catalyst in a dehydration zone under dehydration conditions to provide an olefin enriched hydrocarbon stream;
- b) contacting the olefin enriched hydrocarbon stream with an ionic liquid catalyst in an oligomerization zone under oligomerization conditions to provide an oligomeric product comprising one or more halogenated components;
- and
- c) contacting the oligomeric product with a hydrodechlorination catalyst in the presence of hydrogen in a hydrodechlorination zone under hydrodechlorination conditions to provide a dechlorinated oligomeric product.
