摘要： Systems and methods are provided for producing an improved product slate during hydrocracking of a feedstock for production of naphtha and distillate fuels. The methods can include use of stacked beds and/or sequential reactors so that a feedstock is exposed to a suitable catalyst under aromatic saturation conditions prior to exposing the feedstock to the hydrocracking catalyst. The catalyst for performing the aromatic saturation process can be a catalyst including a Group VIII noble metal, such as Pt, Pd, or a combination thereof, while the hydrocracking catalyst can include Group VIB and Group VIII non-noble metals.

摘要： A method of rejuvenating a deactivated molecular sieve catalyst, deactivated by use in an olefin oligomerization or aromatics alkylation process, which method comprises contacting the deactivated catalyst with a stream of rejuvenation gas comprising a hydrocarbon product fraction from the process at an elevated temperature and pressure for a time sufficient to effect an increase in catalytic activity of the deactivated catalyst.

摘要： A process unit for the zeolite-catalyzed conversion of light refinery olefins from an FCC unit such as ethylene, propylene, and butylene to gasoline boiling range motor fuels comprises at least two sequential, serially connected reactors connected in parallel to a fractionation section with at one or two fractionators for separating the reactor effluents into product fraction with an optional recycle stream or streams. The configurations according to this scheme allow the adjustment of reactor temperature and/or pressure and/or space velocity to be based on the reactivities of the olefin compounds present in the LPG streams so that the gasoline produced in each reactor will be separated immediately, to reduce over-polymerization of the gasoline in the low severity reactor and to ensure that gasoline formed in the low severity reactor will not be sent to the higher severity reactor e.g. with a higher reactor temperature, where excessive polymerization to undesirable higher molecular with products may take place.
