1. A process for converting one or more C2-C5 linear or branched alcohols to one or more C2-C7 olefins, the process comprising:
contacting a first stream comprising the C2-C5 linear or branched alcohols with a first catalyst in a reactor at a temperature from about 200° C. to about 500° C., gauge pressure from 0 to about 30 bar, and a weight hourly space velocity (WHSV) of at least 0.5 to form a second stream; and
contacting the second stream with a second catalyst in the reactor or in a different reactor operating at a temperature from about 200° C. to about 500° C., gauge pressure from 0 to about 30 bar, and a weight hourly space velocity (WHSV) of at least 0.5, wherein the second catalyst comprises a doped zeolite catalyst that includes boron and phosphorus, thereby forming the one or more C2-C7 olefins.
