        Methanol to gasoline (MTG): Parametric study and validation of the process in a two-zone fluidized bed reactor (TZFBR)

        A. Sanz-Martínez,J. Lasobras,J. Soler,J. Herguido,M. Menéndez 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.113 No.-

        Methanol to Gasoline (MTG) process transforms methanol to hydrocarbons within the boiling point rangeof gasoline. The result is a wide spectrum of products (olefins, paraffins, aromatics and naphthenics,among others), with the total conversion of methanol to hydrocarbons and water. Catalyst deactivationby coke is a main problem in this process. This work aims to determine the feasibility of carrying out theproduction of gasoline from methanol in a two-zone fluidized bed reactor (TZFBR). The hypothesis is thatthe formation of carbonaceous deposits (coke) on the catalyst particles can be counteracted by its combustionin the regeneration zone that this novel reactor presents, thus achieving stable and continuousoperation. In this way, both processes (reaction and regeneration) would be being carried out simultaneouslyin the same reactor (process intensification). The comparison of results between a conventional fluidizedbed reactor and a TZFBR shows that the second one actually provides a better stability over time.
