Latest Patents
One of his latest patents is the "FCC spent catalyst distributor." This invention introduces spent FCC catalyst more uniformly across the dense bed of the regenerator, providing more even contact with regeneration gas. This arrangement helps to avoid hot spots and zones of incomplete combustion. The invention features a fluidized hopper to collect spent catalyst and a horizontally extended header with multiple outlet arms to facilitate catalyst placement into the regenerator. Additionally, the design may incorporate an aeration means to assist catalyst flow, ultimately reducing NO emissions in the flue gas.
Another significant patent is the "Process and apparatus for quick feed contacting with immediate vapor disengagement." This apparatus integrates a catalyst nozzle and a feed nozzle at a joint within a reactor vessel. It includes a disengaging transport conduit in communication with a separator. The inlet to the transport conduit is positioned vertically higher than the joint, which minimizes the amount of catalyst entering the transport conduit along with the vapor product.
