Abstract: A process and an apparatus for reducing the diolefin and oxygenate content of liquefied petroleum gas are disclosed. A first conduit is in fluid communication with a liquefied hydrocarbon source and a vessel. The vessel includes a solid adsorbent disposed on a support. The adsorbent is suitable for adsorbing diolefins and oxygenates. A second conduit is in fluid communication with the vessel for receiving the liquefied hydrocarbons of reduced diolefin and oxygenate content from the vessel. A steam inlet conduit is in fluid communication with a steam source and the vessel for treating the solid adsorbent containing adsorbed diolefins and oxygenates with steam to desorb the diolefins and oxygenates from the solid adsorbent. An amine absorber unit for reducing the hydrogen disulfide content of the liquefied hydrocarbon can be in fluid communication with the vessel.

Abstract: Apparatuses and processes are provided for stripping gaseous hydrocarbons from particulate material. One process comprises the step of contacting particles containing hydrocarbons with a stripping vapor in countercurrent flow to remove at least a portion of the hydrocarbons with the stripping vapor to form stripped particles. Contacting the particles includes advancing the particles down a sloping element of a structured packing toward a reinforcing rod that is disposed along a lower channel portion of the sloping element. The particles are advanced over the reinforcing rod. The particles are contacted with the stripping vapor that is rising up adjacent to the lower channel portion.

Abstract: A process for generating refrigeration, electricity or work utilizing a sorption system is disclosed. The sorption system includes a sorbent material and a fluid, in which the sorbent material and fluid in combination have a pressure index of at least 1.2.

Abstract: A process and catalyst for improving the yield of propylene from residual oil feedstock includes obtaining residual oil feedstock from a vacuum distillation tower. The residual oil feedstock has contaminant metals such as sodium or vanadium. The residual oil feedstock is contacted with a cracking catalyst in a catalytic cracking zone to make products. A ZSM-5 zeolite, a binder, a filler and a metal trap are components of the cracking catalyst. The metal trap has a trapping agent in an outer shell of the catalyst, a trapping agent in the ZSM-5 binder or combinations thereof. After reacting, the cracking catalyst is separated from the products in a separator zone, then regenerated by combusting coke deposited on a surface of the cracking catalyst in an oxygen-containing environment. The cracking catalyst is returned to the catalytic cracking zone. The catalyst with the metal trap is also disclosed.
