摘要： 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.

摘要： A process for steam or dry reforming of hydrocarbons in a reforming reactor, comprising the steps of: (a) passing a feedstock, comprising one or more hydrocarbons together with steam and/or CO2, through a first catalytic zone at an elevated temperature, to form a partly reformed process gas, wherein the first catalytic zone comprises one or more elongate conduits, each containing reforming catalyst; and (b) passing the partly reformed process gas through a second catalytic zone at an elevated temperature, so as to form a reformed gas stream, wherein the second catalytic zone comprises one or more elongate conduits, each containing reforming catalyst; wherein the process further comprises the combustion of a fluid fuel with a combustion-sustaining medium in an exothermic combustion region, to form a hot combustion products stream, wherein the exothermic combustion region is adjacent to and laterally surrounds each of the second catalytic zone elongate conduits.

摘要： A process for hydroprocessing a renewable feedstock in a fixed-bed reactor system having at least one catalytic bed involves directing a downward flow of the renewable feedstock to a filtering zone having top-open interstitial portions to receive the downward flow and top-covered annular portions that are in fluid communication with a headspace between the filtering zone and a catalytic zone. The feedstock flows from the interstitial portions to the annular portions through a filtering material disposed between the interstitial portions and the annular portions, resulting in a filtered feedstock, which then flows to the catalytic zone. In the catalytic zone, filtered feedstock is reacted under hydroprocessing conditions sufficient to cause a reaction selected from the group consisting of hydrogenation, hydrodeoxygenation, hydrodenitrogenation, hydrodesulphurization, hydrodemetalation, hydrocracking, hydroisomerization, and combinations thereof.

摘要： 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.

摘要： The invention relates to a reactor for performing exothermic equilibrium reactions, especially for producing methanol from synthesis gas in a multistage synthesis with intermediate condensation of the reaction product. The reactor according to the invention has a reactor shell and a multitude of series-connected and mutually fluid-connected reactor cells disposed within the reactor shell, where each of the reactor cells includes a reaction apparatus, a cooling-down apparatus and a phase separation apparatus as reactor cell elements. The reactor has a multitude of reactor planes disposed in a mutually parallel arrangement within the reactor shell, where reactor cell elements of the same kind are disposed in the same reactor plane. The inventive arrangement of the reactor cell elements enables the building of a compact reactor and reduces material stresses within the reactor by the avoidance of large temperature differences within the reactor shell.
