US 2026/0193166 A1 · HYDROGENATION PROCESS AND REACTION SYSTEM FOR A HYDROGENATION PROCESS

Abstract

In a first aspect, the invention relates to a hydrogenation process for the hydrogenation of a compound comprising reacting the compound in a liquid medium with hydrogen in the presence of a heterogeneous hydrogenation catalyst in a reaction vessel, the process comprising: (i) transferring at least a part of the thermal energy generated in the reaction vessel to a cooling medium, preferably a cooling medium stream CMS1, obtaining a cooling medium stream CMS2, which has an increased thermal energy content compared to CMS1; and (ii) transferring at least a part of the thermal energy comprised in cooling medium stream CMS2 to a heat transfer medium stream HTMS1 in a heat pump HP, thereby obtaining a heat transfer medium stream HTMS2, which has an increased thermal energy content compared to HTMS1. A second aspect of the invention is directed to a reaction system for hydrogenation of a compound, preferably for converting a compound having at least one nitro group into the corresponding compound having at least one amino group by hydrogenation.

A reaction system for hydrogenation of a compound, comprising:

(a) a reactor having
(a.1) means for feeding gaseous and liquid materials into the reactor;
(a.2) means for intermixing in the reactor,
(a.3) an outlet for removing reaction mixture from the reactor;
(a.4) at least one inlet for reintroduction of the reaction mixture;
(a.5) circuit lines outside of the reactor in fluid connection to the outlet (a.3) and inlet (a.4), which enable withdrawal of a reaction mixture from the reactor via outlet (a.3) and reintroduction of the reaction mixture into the reactor via the inlet (a.4);
(a.6) at least one heat exchanger arranged within the reactor, outside of the reactor or in the circuit line (a.5), wherein the heat exchanger has at least one inlet (a.6.1) for feeding a cooling medium into the heat exchanger and at least one outlet (a.6.2) for removing the cooling medium from the heat exchanger;
(b) a heat pump comprising
(b.1) at least one inlet (b.1.1) for feeding a cooling medium into the heat pump, and at least one outlet (b.1.2) for removing the cooling medium from the heat pump;
(b.2) at least one inlet (b.2.1) for feeding a heat transfer medium stream into the heat pump, and at least one outlet (b.2.2) for removing the heat transfer medium stream from the heat pump;
wherein the heat pump is built to allow transfer of thermal energy from a cooling medium stream to a heat transfer medium stream;
(c) lines in fluid connection with the at least one heat exchanger (a.6) and the heat pump (b), which are built and arranged
(c.1) to allow transfer of the cooling medium stream coming from the at least one outlet of the heat exchanger (a.6.2) into an inlet of the heat pump (b.1.1) and reintroduction of the cooling medium stream coming from the at least one outlet (b.1.2) for removing the cooling medium from the heat pump to the at least one inlet (a.6.1) for feeding a cooling medium into the heat exchanger;
and
(c.2) to allow introduction of a heat transfer medium stream into the at least one inlet (b.2.1) of the heat pump for feeding a heat transfer medium stream into the heat pump and removal of a heat transfer medium stream from the at least one outlet (b.2.2) of the heat pump for removing the heat transfer medium stream of the heat pump.
