Abstract

Stability of catalysts under steam and hot water environment is a crucial issue in upgrading of water-containing feedstocks such as biomass and heavy oil. The hydrothermal stability of MTT zeolite in hot water under autogenous pressure was investigated at 473 K. The effect lanthanum (La) and cerium (Ce) on the hydrothermal behavior of MTT zeolite were also studied under the same condition. The parent MTT zeolite, as well Ce and La modified zeolites showed remarkable stability in hot water. Minimal losses in textural properties originated from the hydrolysis of Si-O-Si and Si-O-Al bonds in the zeolite framework. The study shows the potential of the MTT zeolite as a catalyst for biomass conversion and heavy oil upgrading.
