Reaction Enhancement of Heterogeneously Catalyzed Reactions by Concentration Forcing. Technical Progress Report, September 1, 1984-July 15, 1985

摘要

Highlights of progress accomplished during the period of September 1, 1984 to July 15, 1985 are summarized. The following tasks were performed: (1) Developed a phenomenological model for the reaction sequences in ammonia synthesis at pressures up to 150 psia that permit us to correctly predict the conversion performance of reactors which operate either at steady state or under cyclic (transient) conditions resulting from variations in feed composition such as in concentration forcing. (2) Conducted theoretical studies, both analytical and numerical, on the behavior of adsorption/desorption (A/D) models with Eley-Rideal kinetic steps under forced-concentration operating conditions in distributed systems such as fixed-bed plug-flow reactors. (3) Upgraded the fixed-bed reactor system and made design changes so that it can operate at pressures up to 1000 psia for continued mechanistic and behavioral studies of ammonia synthesis as well as methanol synthesis under conditions of concentration forcing of the feed. (4) Completed construction of a novel annular gradientless reactor facility (lumped system) for studying methanol synthesis from CO and H sub 2 at steady state and under concentration forcing conditions for pressures up to 700 psia and temperatures up to 250 exp 0 C.
