  • Publication number: 20230363415
    Abstract: The invention relates to a process for the continuous production of an adsorption product of a nitrooxy-functional organic compound adsorbed on the surface of a particulate adsorbent material, the process comprising the steps of: continuously feeding particulate adsorbent material into an elongated cavity; continuously conveying the material within the cavity in a downstream direction; continuously spraying a liquid adsorbate onto the particulate adsorbent material, wherein the liquid adsorbate comprises the nitrooxy-functional organic compound; continuously agitating the mixture thus obtained to form the adsorption product; and continuously removing the adsorption product from the cavity. The invention further relates to an adsorption product obtained by such process and the use of such adsorption product in ruminant nutrition.
