  • Patent number: 5308476
    Abstract: A resid refining reactor has an ebullated catalyst bed. Hydrogen gas is released into the catalyst bed at a point which is far enough above a distributor plate at the bottom of the catalyst bed to form a gas updraft in a committed zone through the bed. This committed updraft causes a reduction in gas holdup which increases the residence time of a liquid phase in the catalyst bed.

  • Patent number: 5305209
    Abstract: A novel method for characterizing multilayer subterranean reservoirs comprising forming a single layer reservoir model representative of the flow parameters of the multilayer reservoir and developing a set of predicted flow rates from a numerical reservoir simulator. The predicted flow rates are scaled to form a set of dimensionless flow rates. Differences between actual reservoir flow rates and predicted flow rates obtained from the dimensionless flow rates, are minimized automatically to obtain estimates of flow parameters for each layer of the multilayer reservoir. Additionally, for a given set of flow parameters, the optimum injection and production well patterns as well as injection and production well operating conditions can be determined for producing hydrocarbon from the multilayer reservoir.

  • Patent number: 5303547
    Abstract: An exhaust gas emissions control system lowers cold-start hydrocarbon emissions by using heat exchange structure to lower the temperature of exhaust gas prior to the exhaust gas passing through a hydrocarbon adsorbent and using the extracted heat to heat a catalytic converter to its light-off temperature. In some embodiments, multi-component hydrocarbon adsorbers effective under different operating conditions further reduce cold-start hydrocarbon emissions.
