    Abstract: Systems and methods are provided for controlling the flow and transport of catalyst particles within a reaction system. The flow of catalyst particles can be managed using a rotating disc or wheel that is configured within a roller volume to allow for control over the rate of catalyst flow while reducing or minimizing attrition of the catalyst particles. This can be achieved in part by maintaining a relationship between the center of the rotating disc, the inlet for catalyst particles to the roller volume, and the top wall of the roller volume so that catalyst particles are not exposed to compressive forces and/or abrasion during rotation of the disc. Additionally or alternately, the disc and roller volume surfaces can be configured to reduce or minimize the potential for catalyst particles to become trapped in "dead space" regions within the roller volume. By using a disc to provide force for transport of particles through the roller volume, the speed of catalyst movement can be controlled at relatively slow catalyst flow rates with a reduced or minimized risk for clogging or plugging within the roller volume.

    Abstract: Processes are provided herein for producing naphtha boiling range products with a desired sulfur content by reducing the mercaptan content of the naphtha boiling range products after the products exit a hydroprocessing stage. Due to mercaptan reversion, naphtha boiling range products that contain even small amounts of olefins can have a higher than expected sulfur content after hydroprocessing. In order to reduce or mitigate the effects of mercaptan reversion, microchannel reactors (or microreactors) can be placed in a processing system downstream of a reactor that produces a low sulfur naphtha product. The microreactors can include a coating of metals that have activity for hydrodesulfurization. By passing at least a portion of the naphtha product through the downstream microreactors, the mercaptans formed by reversion reactions can be reduced or eliminated, resulting in a naphtha product with possessing a very low sulfur content.

    Abstract translation: 本文提供了通过在产物离开加氢处理阶段之后还原石脑油沸程产物的硫醇含量来生产具有所需硫含量的石脑油沸程产物的方法。 由于硫醇反转，含有甚至少量烯烃的石脑油沸程产品在加氢处理后可能具有高于预期的硫含量。 为了减少或减轻硫醇反转的影响，微通道反应器（或微反应器）可以放置在产生低硫石脑油产物的反应器下游的处理系统中。 微反应器可以包括具有加氢脱硫活性的金属涂层。 通过使至少一部分石脑油产物通过下游微反应器，可以减少或消除由反转反应形成的硫醇，导致具有非常低的硫含量的石脑油产品。

    Abstract: This invention relates to an ultrafiltration process for separating a heavy hydrocarbon stream to produce an enriched saturates content stream(s) utilizing an ultrafiltration separations process. The enriched saturates content streams can then be further processed in refinery and petrochemical processes that will benefit from the higher content of saturated hydrocarbons produced from this separations process. The invention may be utilized to separate heavy hydrocarbon feedstreams, such as whole crudes, topped crudes, synthetic crude blends, shale oils, oils derived from bitumen, oils derived from tar sands, atmospheric resids, vacuum resids, or other heavy hydrocarbon streams into enriched saturates content product streams. The invention provides an economical method for separating heavy hydrocarbon stream components by molecular species instead of molecular boiling points.
