Abstract
A process for the synthesis of methanol from an input stream of synthesis gas, comprising the following steps: subjecting a portion of said input stream as feed stream to an adiabatic reactive step, providing an effluent containing methanol and unreacted synthesis gas; quenching of said effluent with a further portion of said input stream, providing a quenched stream; subjecting said quenched stream to an isothermal reactive step, providing a methanol-containing product stream.

A process for the synthesis of methanol from an input stream of synthesis gas, comprising the following steps:
- subjecting a portion of said input stream as feed stream to an adiabatic reactive step, providing an effluent containing methanol and unreacted synthesis gas;
- quenching of said effluent with a further portion of said input stream, providing a quenched stream;
- subjecting said quenched stream to an isothermal reactive step, providing a methanol-containing product stream;
- wherein said isothermal reactive step is carried out in a catalytic bed comprising heat exchange bodies.
A reactor system for the synthesis of methanol from an input stream of synthesis gas, comprising:
- an adiabatic catalytic zone, receiving a portion of said input stream as feed stream, and providing an effluent containing methanol and unreacted synthesis gas;
- a quench line of a further portion of said input stream which mixes with said effluent, providing a quenched stream;
- an isothermal catalytic zone, receiving said quenched stream and providing a methanol-containing product stream;
- said isothermal catalytic zone comprising a catalytic bed and heat exchange bodies immersed in the catalytic bed.
