摘要： An improved process for reducing SOx in the flue gas from FCC regenerators operated in complete combustion mode is disclosed. The FCC riser is modified to include an SOx desorption zone (D) upstream from the zone in the riser in which regenerated cracking catalyst (A) contacts hydrocarbon feedstock (E). The circulating catalyst inventory (A) includes a regenerable SOx adsorbent. In the SOx desorption zone (D), the hot circulating catalyst inventory (A) is mixed with a reducing gas (B) and water vapor (C) and the gas/solid mixture is maintained in that zone for sufficient time to desorb.

摘要： A process and apparatus for upgrading a petroleum charge of crude oil or residual fractions thereof to provide a product with substantially reduced heavy metals content and Conradson Carbon number. The charge is dispersed into a descending curtain of heated, substantially inert contact material. This contact material preferably has a conversion rate not substantially greater than 10% in the CAT D test. The vapors generated on contact of the charge with the curtain are collected immediately from the side of the curtain opposite from where the charge is dispersed. The collected vapors are cooled to avoid thermal cracking. The product is suitable for catalytic cracking or use as heavy fuel or heavy fuel precursor.
