US 2026/0184666 A1 · HYDROGENATION PROCESS AND REACTION SYSTEM FOR HYDROGENATION

Abstract

In a first aspect, the invention relates to a hydrogenation process for the conversion 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 comprised in a reaction apparatus, the process comprising: (i) transferring at least a part of the thermal energy generated in the reaction vessel to a heat transfer medium in a heat exchanger HE, preferably to a heat transfer medium stream HTMS1, obtaining a heat transfer medium stream HTMS2, which has an increased thermal energy content compared to HTMS1; (ii) increasing the pressure of the heat transfer medium stream HTMS2 having a pressure p2, thereby obtaining a heat transfer medium stream HTMS3, which has an increased pressure p3 compared to HTMS2. A second aspect of the invention relates to a reaction system for hydrogenation.
