A sorption rotor has end faces and is rotatably journaled to travel during a revolution through an inflow sector and an outflow sector. The rotor is made of a matrix material having a honeycomb structure with axially throughgoing flow passages. The matrix material is constituted of cellulose paper modified by a ceramic material infiltrated by a sol-gel system or a gel-forming low-viscosity liquid into the matrix.
