Abstract: A quench mixing device (100, 200, 300) is disclosed for mixing multiphase process fluids in 5 the inter-bed region of a concurrent downflow reactor (10) for obtaining homogeneity of the temperature and chemical composition of the mixed stream. The quench mixing device comprises of outer mixing zone (109), inner mixing zone (120), swirl mixing zone (151) and exit zone. Due to the position of the disperser (142), the liquid coming from above is dispersed in droplets. The fluid impact on the other side of the outer mixing zone. The gas is bubbled into 0 liquid in the inner mixing zone. The fluids enter the swirl mixing zone via two-phase duct (131) which is shaped to have low pressure loss and high velocity at the outlet to induce dispersed regime. The outlet of the two-phase duct is placed such that liquid is injected into the swirl zone below liquid surface, causing increased momentum for inducing liquid swirl in the swirl zone and increased number of rotations.

Abstract: A process for upgrading a hydrocarbon feed, such as crude oil or other heavy oils, may include hydrotreating a hydrocarbon feed in a hydrotreating unit to produce a hydrotreated effluent that includes asphaltenes, coke precursors, or both. The process further includes hydrocracking the hydrotreated effluent in a hydrocracking unit to produce a hydrocracked effluent, adsorbing at least a portion of the asphaltenes, coke precursors, or both, from the hydrotreated effluent, the hydrocracked effluent, or both, separating the hydrocracked effluent into at least an upgraded lesser-boiling effluent and a greater-boiling effluent in a hydrocracked effluent separation system, and steam cracking the upgraded lesser-boiling effluent to produce olefins, aromatic compounds, or combinations of these. The process may further include recycling the greater boiling effluent back to the hydrotreating unit and hydrocracking a middle distillate effluent from the hydrocracked effluent separation system. Systems for conducting the processes are also disclosed.

Abstract: Catalyst systems are provided for reforming of hydrocarbons, along with methods for using such catalyst systems. The catalyst systems can be deposited or otherwise coated on a surface or structure, such as a monolith, to achieve improved activity and/or structural stability. The metal oxide support layer corresponds to a metal oxide support layer that is thermally phase stable at temperatures of 800°C to 1600°C, such as alpha-alumina. The catalyst systems can be beneficial for use in cyclical reaction environments, such as reverse flow reactors or other types of reactors that are operated using flows in opposing directions and different times within a reaction cycle, e.g. a catalyst system comprising nickel and alpha-alumina for cyclic methane reforming.

Abstract: Systems and methods are provided for using size-reversing materials in vessels where direct heating is used to at least partially provide heat for reforming reactions under cyclic reforming conditions. An example of a size-reversing material is the combination of NiO and AI2O3. It has been discovered that size-reversing materials can undergo a phase transition that can assist with re-dispersion of metal at elevated temperatures. This can assist with maintaining catalytic activity for reforming over longer time periods in the presence of cyclic reforming conditions.
