Abstract
A method for converting methanol to gasoline boiling range hydrocarbons is disclosed. In an aspect the method includes feeding crude methanol from a methanol synthesis reactor to a methanol separation vessel to recover a methanol stream in a vapor phase; and without condensing the methanol stream, feeding the methanol stream in the vapor phase to a reactor containing a conversion catalyst for converting methanol to at least one of dimethyl ether or gasoline boiling range hydrocarbons.

A method for converting methanol to gasoline boiling range hydrocarbons comprising:
- feeding crude methanol from a methanol synthesis reactor to a methanol separation vessel to recover a methanol stream in a vapor phase;
- and
- without condensing the methanol stream, feeding the methanol stream in the vapor phase to a reactor containing a conversion catalyst for converting methanol to at least one of dimethyl ether or gasoline boiling range hydrocarbons.
A method for converting methanol to gasoline boiling range hydrocarbons comprising:
- feeding crude methanol from a methanol synthesis reactor to a methanol separation vessel to recover a methanol stream in a vapor phase;
- and
- feeding the methanol stream in the vapor phase to a reactor containing a conversion catalyst for converting methanol to at least one of dimethyl ether or gasoline boiling range hydrocarbons, wherein the separation vessel has a pressure that is substantially same as that of the reactor.
A method for converting methanol to gasoline boiling range hydrocarbons comprising:
- feeding crude methanol from a methanol synthesis reactor to a methanol separation vessel to recover a methanol stream in a vapor phase;
- and
- without condensing the methanol stream, compressing the methanol stream and feeding the methanol stream in the vapor phase to a reactor containing a conversion catalyst for converting methanol to at least one of dimethyl ether or gasoline boiling range hydrocarbons.
