Method for synthesising a liquid organic hydrogen carrier (LOHC) loaded with hydrogen using hydrogen produced from a methanisation digestate

Abstract

A synthesis process of a liquid organic hydrogen carrier charged with hydrogen, Hn-LOHC, wherein a methanisation digestate is used as a hydrogen source, including at least the steps of: a) production of gaseous ammonia from the methanisation digestate; b) division of the gaseous ammonia produced in step a) into a first and a second flow; c) catalytic amination of a liquid organic hydrogen carrier not charged with hydrogen, H0-LOHC, by reaction with the gaseous ammonia from the first flow to convert the H0-LOHC into an aminated H0-LOHC and produce hydrogen; d) catalytic dissociation of gaseous ammonia from the second flow to produce hydrogen; and e) catalytic hydrogenation of the aminated H0-LOHC obtained in step c), by reacting with the hydrogen produced in steps c) and d), whereby the Hn-LOHC is obtained.
