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...
