System and method for a microreactor

A microreactor system comprising a plurality of cartridge microreactors connected with each other in series and wherein each cartridge microreactor comprises:

• a tubular heater comprising an inner tube surrounded by an outer heater sheath;
• a metal capillary reaction tubing comprising an inlet port and an outlet port and being wrapped around the tubular heater so that it is in intimate thermal contact with the heater sheath;
• and
• a brazing alloy permanently bonding the tubular heater with the metal capillary reaction tubing;
• and
• wherein the metal capillary reaction tubing is configured to be heated by the tubular heater and is configured to receive one or more reactants through the inlet port and to allow the reactants to react under a selected temperature and pressure and to produce one or more products exiting through the outlet port.

A microreactor system comprising a plurality of cartridge microreactors connected with each other in parallel and wherein each cartridge microreactor comprises:

• a tubular heater comprising an inner tube surrounded by an outer heater sheath;
• a metal capillary reaction tubing comprising an inlet port and an outlet port and being wrapped around the tubular heater so that it is in intimate thermal contact with the heater sheath;
• and
• a brazing alloy permanently bonding the tubular heater with the metal capillary reaction tubing;
• and
• wherein the metal capillary reaction tubing is configured to be heated by the tubular heater and is configured to receive one or more reactants through the inlet port and to allow the reactants to react under a selected temperature and pressure and to produce one or more products exiting through the outlet port.
