Reliable estimates of catalyst deactivation parameters are difficult to get from conventional experiments at constant space velocity where conversion declines with time on stream, or when temperature is adjusted to compensate for the loss of catalyst

The question of multiple steady states and their stability arises whenever one considers the control of large nonlinear systems. One such system, the fluidized catalytic cracker (FCC), is the subject of this paper. Using a new FCC model representativ

An improved and updated model for modern fluidized bed catalytic crackers (FCC) is presented. It is based on a more detailed kinetic description of the kinetics in both the reactor and the regenerator using the full range of published data both on FC

The heat transfer coefficient from a heated pipe in a trickle-bed catalytic reactor was correlated with combined gas and liquid flow rates along with fluid and packing physical properties. The correlation is readily applicable for flow rate measureme

A steady-state, two-dimensional model for cocurrent gas and liquid flow in a trickle-bed reactor is described. First, the model is developed along with appropriate boundary conditions for multidimensional flow. Then, we discuss the numerical solution

This two-dimensional model of a moving-bed shale oil retort accounts for the major physical interactions of convective heating and kerogen decomposition coupled with the shale and gas flow distributions. Data in a small-sale apparatus support a solid

Multiplicity features of autocatalytic reactions in isothermal catalyst particles with diffusion interaction are presented. Discussed also are two types of autocatalytic reactions—A + B → 2B (quadratic) and A + 2B → 3B (cubic)—and a decay rea
