Abstract
A process for making ethylbenzene and/or styrene by reacting toluene with methane in one or more microreactors is disclosed. In one embodiment a method of revamping an existing styrene production facility by adding one or more microreactors capable of reacting toluene with methane to produce a product stream comprising ethylbenzene and/or styrene is disclosed.
Claims11
A process for making ethylbenzene and styrene comprising:
- reacting toluene and methane in one or more microreactors to form a first product stream comprising ethylbenzene and styrene;
- wherein the one or more microreactors comprises a reaction zone and wherein the one or more microreactors are capable of dissipating heat to maintain the reaction zone within a desired temperature range for reacting toluene and methane to form ethylbenzene and styrene;
- wherein the reaction zone comprises one or more catalyst sites comprising a catalyst selected from the group consisting of X zeolite, Y zeolite, mordenite, silicalite, and combinations thereof;
- wherein the catalyst is modified with molybdenum, sodium or other basic ions.
