  • Patent number: 9434894
    Abstract: A method and apparatus for processing hydrocarbons are described. The method includes fractionating a hydrocarbon stream to form at least two fractions. The first fraction is reformed to form a reformate stream, and the reformate stream is introduced into an aromatics processing zone to produce aromatic products. At least a portion of the second fraction is cracked in a fluid catalytic cracking unit. A selectively hydrogenated light naphtha stream is formed by separating the cracked hydrocarbon stream into at least two streams and selectively hydrogenating the light naphtha stream, or selectively hydrogenating the cracked hydrocarbon stream and separating the hydrogenated cracked hydrocarbon stream into at least two streams. Aromatics are extracted from the selectively hydrogenated light naphtha stream forming an extract stream and a raffinate stream. The extract stream is hydrotreated, sent to the aromatics processing zone to produce additional aromatic products.

  • Publication number: 20160083313
    Abstract: A process is disclosed for the aromatization and alkylation of light aliphatic hydrocarbons, such as propane or propylene, into aromatic hydrocarbons. The process provides increased aromatics production and decreases methane and ethane production. This improvement for the aromatization and alkylation of light aliphatic hydrocarbons is achieved by adding a benzene stream to the light paraffin feed components.

  • Patent number: 8927798
    Abstract: A new family of coherently grown composites of TUN and IMF zeotypes has been synthesized and shown to be effective catalysts for aromatic transformation reactions. These zeolites are represented by the empirical formula: NanMmk+TtAll-xExSiyOz where “n” is the mole ratio of Na to (Al+E), M represents at least one meta, “m” is the mole ratio of M to (Al+E), “k” is the average charge of the metal or metals M, T is the organic structure directing agent or agents, “t” is the mole ratio of N from the organic structure directing agent or agents to (Al+E), and E is a framework element such as gallium. The process involves contacting at least a first aromatic with the coherently grown composites of TUN and IMF zeotypes to produce at least a second aromatic.

  • Patent number: 8926829
    Abstract: A process for reforming a hydrocarbon stream is presented. The process involves splitting a naphtha feedstream to at least two feedstreams and passing each feedstream to separation reformers. The reformers are operated under different conditions to utilize the differences in the reaction properties of the different hydrocarbon components. The process utilizes a common catalyst, and common downstream processes for recovering the desired aromatic compounds generated.

  • Patent number: 8877670
    Abstract: Catalysts are disclosed comprising fibrous substrates having silica-containing fibers with diameters generally from about 1 to about 50 microns, which act effectively as “micro cylinders.” Such catalysts can dramatically improve physical surface area, for example per unit length of a reactor or reaction zone. At least a portion of the silica, originally present in the silica-containing fibers of a fibrous material used to form the fibrous substrate, is converted to a zeolite (e.g., having a SiO2/Al2O3 ratio of at least about 150) that remains deposited on these fibers. The fibrous substrates possess important properties, for example in terms of acidity, which are useful in hydroprocessing (e.g., hydrotreating or hydrocracking) applications.
