Abstract: A catalyst material for oxidative dehydrogenation (ODH) comprising molybdenum, vanadium, oxygen, and an element chosen from iron, aluminum, and beryllium is provided. The product stream from an ODH reactor (202) is directed to a quench tower (204) to remove a waste stream comprising oxygenates. A flooded gas mixer is used to premix oxygen-containing gas, alkane-containing gas and heat- removal gases prior to introduction into the ODH reactor.

Abstract: A system for methanol synthesis from a synthesis gas rich in hydrogen and CO2/CO that comprises a first adiabatic reactor (11) with a structure comprising an inlet stream (10), a first catalytic bed (12), one Venturi type mixing element (13), a first divergent nozzle (14), a second catalytic bed (27) and one outlet stream (28) all of them connected sequentially to each other; a first heat exchanger (15) connected to the outlet stream (28) downstream the reactor (11); a condenser (16) connected to the heat exchanger (15) downstream of the heat exchanger (15); a separator (18) connected to the condenser (16); a first cold gas stream (19) joining the separator (18) to both the first heat exchanger (15) and the first Venturi type mixing element (13); a first outlet stream (21) joining the heat exchanger (15) to a second adiabatic reactor (24) similar to the first adiabatic reactor (11).

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.
