Fractional Catalytic Pyrolysis Technology for the Production of Upgraded Bio-oil using FCC Catalyst
… inert atmosphere in the presence of an acid catalyst or zeolite to promote deoxygenation and cracking of the primary vapors into hydrocarbons and small oxygenates. This dissertation examines the utilization of conventional fluid catalytic cracking (FCC) catalyst in the fractional catalytic …

Hydrothermal aging of zeolite-based catalysts
In this study the RE-USY (Davision GO-40) FCC catalyst, a composite of RE-USY zeolite and alumina-silica gel matrix, was treated hydrothermally under simulated FCC regenerator conditions in a laboratory scale fluidized bed. Fresh and steam-aged catalysts were characterized by surface area reduction …

Bubbling to turbulent regime transition in a 2D catalytic fluidized bed reactor
… (2D) catalytic fluidized bed reactor. Commercial FCC catalyst impregnated with Fe2O3 was used at superficial gas velocities ranging between 0.006 m/s and 0.55 m/s. The onset velocity of the turbulent regime (uc) was determined as 0.4 m/s. The catalyst activity was optimized so that the effect of …

Cold model of a vibrated-bed microreactor capable of varying Peclet number at fixed weight hourly space velocity providing a tool for simulating an important feature of the reaction kinetic scene in large catalytic fluid beds
… on a microscale, using approximately 5 grams of catalyst. Realization of a hot design of the microreactor (a task for another student) should permit the industrial chemist or chemical engineer, working at laboratory bench scale, quickly and inexpensively, to determine the sensitivity of a …
