Abstract
The present subject matter relates to co-producing H-CNG and CNTs. The process comprises adding catalyst to a first reactor () and activating the catalyst and performing a reaction to obtain H-CNG and CNTs. At a first predetermined time after reaction has progressed in the first reactor (), catalyst is added to a second reactor (), activated, and then the reaction proceeds simultaneously in the first reactor () and second reactor (). The use of multiple reactors with staggered start times helps in the continuous co-production of H-CNG and CNTs. Catalyst preparation process is integrated with the co-production process for efficient heat recovery. The first and second reactors are fluidized bed reactors with cantilever trays having weirs for controlling the residence time of the catalyst in the reactor and thereby controlling the purity of CNTs produced.
