  • Catalyst bed platform with center support pipe
    Patent number: 9126168
    Abstract: A structure and method are provided for adding a catalyst bed platform to an existing reactor without welding to the structural portion of the reactor walls. The structure is constructed from components that can be passed through an existing opening in a reactor. The structure allows a catalyst bed in an existing reactor to be divided into catalyst beds with a reduced length to diameter ratio.
    Type: Grant

  • Feed injector
    Patent number: 7407572
    Abstract: This invention relates to an apparatus and process for atomizing a petroleum feed. More particularly, a liquid petroleum feed is atomized with an atomization apparatus in which the apparatus has an orifice that produces a generally flat spray pattern of finely dispersed feed prior to contacting catalyst in a fluid catalytic cracking zone. The orifice has a general aspect ratio greater than 1.0 and a ratio of perimeter length-to-cross-sectional area greater than 1.5 relative to a perimeter-to-cross-sectional area ratio of a circular orifice of equivalent area. The apparatus can be used to atomize feed injected into the cracking zone of a fluid catalytic cracker.
