    摘要： This disclosure relates to devices, e.g., baffle plate and combination dipleg valve/baffle devices, for use in achieving rapid disengagement of entrained hydrocarbons vapors, especially in high flux spent catalyst flow exiting from a cyclone separator dipleg in a fluidized catalytic cracking (FCC) unit. The baffle plate is preferably located near and typically below the catalyst dipleg of a fluid catalytic cracking reactor or separation zone and comprises a baffle plate body member having a surface, and in preferred embodiments also includes one or more apertures located on at least a portion of the surface. The valve/baffle is located at the outlet of the catalyst dipleg and comprises a combination valve and catalyst baffle in which the valve/baffle is designed to allow the top surface of the valve/baffle to seat against the dipleg outlet until the weight of the catalyst above the valve/baffle forces it to open. This disclosure also relates to FCC units that include the devices, and FCC methods utilizing the devices.

    摘要： A method for the removal of nitrogen compounds from FCC feed or from catalytically cracked distillates including FCC cycle oils by using formaldehyde to selectively couple organic heterocyclic nitrogen species in the FCC feed or FCC distillate to form higher boiling coupling products out of the boiling range of FCC distillate. Removal of the nitrogenous compounds improves the operation of subsequent hydrodesulfurization steps needed for the distillate fraction to conform to low sulfur standards. The formaldehyde is preferably used in the form of paraformaldehyde. The reaction between the nitrogenous compounds in the cycle oil fraction with the formaldehyde is conveniently carried out in the cycle oil pumparound circuit of the FCC main column.

    摘要： The present invention relates to a process for the selective conversion of hydrocarbon feed having a Conradson Carbon Residue content of 0 to 6 wt %, based on the hydrocarbon feed. The hydrocarbon feed is treated in a two-step process. The first is thermal conversion and the second is catalytic cracking of the products of the thermal conversion. The present invention results in a process for increasing the distillate production from a hydrocarbon feedstream for a fluid catalytic cracking unit. The resulting product slate from the present invention can be further varied by changing the conditions in the thermal and catalytic cracking steps as well as by changing the catalyst in the cracking step.
