摘要: One exemplary embodiment can be a process for fluid catalytic cracking. The process may include providing a torch oil to a stripping section of a first reaction zone, which in turn can communicate at least a partially spent catalyst to a regeneration zone for providing additional heat duty to the regeneration zone.

摘要: One exemplary embodiment can be a process for fluid catalytic cracking. The process may include providing a first feed having a boiling point of about 180-about 800° C. to a first riser reactor, and providing a second feed having first and second parts to a second reactor. Typically, the first part includes one or more C5-C12 hydrocarbons and a second part includes one or more C4-C5 hydrocarbons. Generally, an effective amount of the second part is combined with the first part to maximize production of propene.

摘要: A process for mixing regenerated and carbonized catalyst involves obstructing upward flow of catalyst by one or more baffles between a catalyst inlet and a feed distributor. Each catalyst stream may be passed to opposite sides of a riser. Baffles obstruct upward flow to effect mixing of regenerated and carbonized catalyst to obtain a more uniform temperature and catalyst mixture before contacting the feed.

摘要: A process separates solids from gas in a vessel using cyclones. The cyclones have centers located at different distances from a center of the vessel, but the inlets to the cyclones are located at the same distance from the center to balance the proportions of catalyst fines entering each cyclone.

摘要: Apparatus and process for increasing mixing in a regenerator. Streamlines of gas and some catalyst may form in a regenerator as a result of cyclone inlet horns positioned in the same direction. Overall mixing in the regenerator may decrease because of these streamlines. A dampening device may be used to interrupt the streamlines and increase mixing in the regenerator. The dampening device may be a baffle and direct streamlines from the outside of the chamber toward the center to collide and mix. In another embodiment, a dampening device may be a secondary disengager positioned above the disengager near the center of an upper chamber of a regenerator. The secondary disengager may be a T-disengager or may have an inverted can arrangement that may discharge gas and catalyst near the center of the upper chamber and interrupt the streamlines. In another embodiment, a dampening device may have swirl arms and may be positioned near the center of the regenerator where streamlines may enter a swirl arm and be redirected counter to the direction of flow. Such additions to a regenerator may be relatively unobtrusive, inexpensive, and simple for a retrofit or design modification and may result in an improved combustion efficiency at high rates by enhancing the lateral blending of spent and regenerated catalyst, increased lateral mixing of cool, fuel-rich and hot, O2-rich flue gases from opposite sides of the regenerator in the dilute phase. In addition, the mean residence time of flue gas in the dilute phase may result in NOX reduction.
