    Abstract: The liquid feed nozzle assemblies for a circulating fluid bed reactor comprise (i) a throttle body premixer to combine liquid feed with atomization steam to form a liquid feed/steam mixture comprising gas bubbles in liquid; (ii) a conduit connected to the premixer and to a discharge nozzle to convey a flow of the liquid/steam mixture created by the premixer to the nozzle body; (iii) a discharge nozzle connected to the flow conduit to shear the liquid feed/steam mixture to create liquid feed droplets of reduced size and (iv) a disperser at the outlet of the discharge nozzle to provide a spray jet of liquid feed having an increased surface area relative to a cylindrical jet. The nozzle assembles are particularly useful in fluid coking units using heavy oil feeds such a tar sands bitumen.

    Abstract: In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of C4 to C12 olefinic and aromatic hydrocarbons is recovered from the first stream and at least part of the second stream is contacted with a catalyst in the absence of added hydrogen under reaction conditions including a temperature of about 450° C. to about 70° C. effective to dealkylate, transalkylate, crack and aromatize components of the second stream to produce a third stream having an increased benzene and/or toluene content compared with the second stream and a C3− olefin by-product. The C3− olefin by-product and a fourth stream comprising toluene are then recovered from the third stream.

    Abstract: Methods for extracting a kerogen-based product from subsurface (oil) shale formations rely on chemically modifying the shale-bound kerogen using a chemical oxidant so as to render it mobile. The oxidant is provided to a formation fluid in contact with the kerogen in the subsurface shale. An alkaline material is also provided to the formation fluid to mobilize organic acids which are produced during oxidation of the kerogen. A mobile kerogen-based product which includes the organic acids is withdrawn from the subsurface shale formation and further processed to isolate the organic acids contained therein. These organic acids are valuable as hydrocarbon products for creating commercial products and a portion of these organic acids can also be used in the process for extracting the kerogen-based product from the subsurface shale formation.

    Abstract: A heat exchanger for cooling reaction gas. A cooled tube receives hot reaction gas from a hot, uncooled tube. The cooled tube comprises a cooled inner tube and a tubular jacket that extends about the inner tube. A tubular connection is disposed between the uncooled and the cooled tubes, and includes a fork-shaped inlet head via which the inner tube is in communication with the uncooled tube. The inlet head is provided with an outer tubular section and an inner tubular section between which is disposed an intermediate space filled with heat-insulating material. The outer tubular section is connected to the tubular jacket. The inner tubular section is spaced slightly axially from the inner tube and is provided with an edge region that juts outwardly and is spaced slightly axially from the inner tube, this slight axial spacing being equal to or less than a maximum thermal expansion of the inlet head. A U-shaped sealing ring is disposed between facing end faces of the inner tube and the inner tubular section, and is disposed in a recess formed in the end face of the inner tubular section, the recess being disposed radially outwardly of the edge region of the inner tubular section.
