  • Publication number: 20220298437
    Abstract: Implementations of the disclosed subject matter provide a process for upgrading refinery residue feedstock. Step a) may include introducing the refinery residue feedstock into a fluidized bed reactor as a solid. In step b), the refinery residue feedstock may be heated to a devolatilizing and thermal cracking temperature in the fluidized bed reactor to produce a product stream comprising gaseous hydrocarbons and solid coke. The gaseous hydrocarbons may be subjected to catalytic hydroprocessing, in step c), in the presence of molecular hydrogen to increase the hydrogen to carbon ratio and lower the average molecular weight of the gaseous hydrocarbons. In step d), the gaseous hydrocarbons may be separated from the solid coke. In step e), the gaseous hydrocarbons from step d) may be subjected to further processing to produce at least one of: C1-C3 hydrocarbons, liquefied petroleum gas, naphtha range hydrocarbons, and middle distillate range hydrocarbons.

  • Patent number: 9796024
    Abstract: A cutting insert includes a body having an upper face, a lower face, a plurality of planar flank faces, bidirectional acute cutting corners and bidirectional obtuse cutting corners joining two adjacent flank faces. A land has a varying width. An annular island includes a plurality of bulged extensions, relatively longer and narrower chip breaking points proximate the acute cutting corners, and relatively shorter and wider chip breaking points proximate the obtuse cutting corners. A chip breaking ramp surface flanks each of the relatively longer and narrower chip breaking points and each of the relatively shorter and wider chip breaking points. The chip breaking ramp surfaces form a series of non-collinear lines that are at a non-zero angle with respect to the cutting edge.
