1. A volatile organic compound reduction apparatus for removing volatile organic compounds from air, the apparatus comprising:
a first and a second rotor element each provided with a plurality of channels, configured to separate the volatile organic compounds from air by adsorption and desorption of the volatile organic compounds to and from the first and second rotor elements;
a first adsorption zone of the apparatus, configured to guide a process airflow through the first rotor element;
a first desorption zone of the apparatus, configured to guide a first regenerating airflow through the first rotor element; and
a converter configured to convert the volatile organic compounds to residual products; wherein
the second rotor element is configured to receive the first regenerating airflow, after passing through the first rotor element, at a second adsorption zone of the apparatus;
a second desorption zone of the apparatus is configured to guide a second regenerating airflow through the second rotor element; and
the converter is configured to receive the second regenerating airflow as concentrated volatile organic compounds, after the second regenerating airflow has passed through the second rotor element;
wherein the first rotor element has a circular configuration with a first diameter (d1) and the second rotor element has a circular configuration with a second diameter (d2);
wherein a volume flow of the first regeneration airflow that passes through the second rotor element is configured to be less than that of the process airflow through the first rotor element; and
wherein the first diameter (d1) is larger than the second diameter (d2).
