Abstract
A catalytic kit for converting a feedstock to aromatics in a dual bed reactor includes a first catalyst A1 configured to promote (1) a conversion of a first part of the feedstock into olefins and (2) a conversion of diene and the olefines into the aromatics; a second catalyst A2 configured to promote a conversion of a second part of the feedstock into formaldehyde; and a third catalyst B configured to promote a conversion of olefines into additional aromatics, where the first and second catalysts A1, A2 are mixed together to be in direct contact with each other.

A catalytic kit for converting a feedstock to aromatics in a dual bed reactor, the catalytic kit comprising:
- a first catalyst A1 configured to promote (1) a conversion of a first part of the feedstock into olefins and (2) a conversion of diene and the olefines into the aromatics;
- a second catalyst A2 configured to promote a conversion of a second part of the feedstock into formaldehyde;
- and
- a third catalyst B configured to promote a conversion of olefines into additional aromatics,
- wherein the first and second catalysts A1, A2 are mixed together to be in direct contact with each other.
A reactor configured for converting a feedstock to aromatics, the reactor comprising:
- a housing divided into an upper chamber and a bottom chamber by a porous divider;
- an inlet configured to receive the feedstock, the inlet-being in fluid communication with the upper chamber;
- an outlet configured to discharge the aromatics from the bottom chamber;
- and
- a catalyst kit having first and second catalysts A1 and A2 distributed in the upper chamber and a third catalyst B distributed in the bottom chamber,
- wherein the first catalyst A1 is configured to promote (1) a conversion of a first part of the feedstock into olefins, and (2) a conversion of diene and a first part of the olefines into the aromatics, the second catalyst A2 is configured to promote a conversion of a second part of the feedstock into formaldehyde, and the third catalyst B is configured to promote a conversion of a second part of the olefines into additional aromatics, and
- wherein the first and second catalysts A1, A2 are mixed together to be in direct contact with each other.
A method for converting a methanol feed to aromatics, the method comprising:
- receiving a catalyst kit having first and second catalysts A1 and A2, and a third catalyst B, wherein each of the three catalysts is different from the other two catalysts;
- loading the first and second catalysts A1 and A2 in an upper chamber of a reactor, wherein the first catalyst A1 is configured to promote (1) a conversion of a first part of the methanol feed into olefins, and (2) a conversion of dienes and a first part of the olefines into the aromatics, and the second catalyst A2 is configured to promote a conversion of a second part of the methanol feed into formaldehyde;
- loading the third catalyst B in a bottom chamber of the reactor wherein the third catalyst B is configured to promote a conversion of a second part of the olefines into additional aromatics;
- supplying the methanol feed to the upper chamber of the reactor;
- and
- converting the methanol feed to the aromatics in each of the upper and bottom chambers,
- wherein the first and second catalysts A1, A2 are mixed together to be in direct contact with each other in the upper chamber.
