Abstract: The present disclosure provides a method for catalytic conversion of waste plastic into liquid fuel. The method comprises thermally decomposing the waste plastic at a temperature in the range of 350 to 650° C. and under a pressure in the range of 0.0010 psi to 0.030 psi, to obtain a gaseous stream. The gaseous stream is further subjected to four stage sequential cooling to a temperature in the range of −5 to −15° C. to obtain a gas-liquid mixture comprising a gaseous fraction and a liquid fraction. The gas-liquid mixture is fed to the gas-liquid separator to obtain the gaseous fraction comprising C1 to C4 hydrocarbons and the liquid fraction comprising liquid fuel. The method of the present disclosure is simple, economical and energy efficient, which provides a high value liquid fuel with enhanced yield.

Abstract: The present application provides systems and methods for producing isononanol and gasoline and diesel blending components. In at least one embodiment of the present systems and methods, a hydrocarbon feed is cracked in a steam cracker to form a first ethylene stream, a first propylene stream, and a C4 stream comprising isobutene and butadiene. The C4 stream is reacted with a methanol stream in a methyl tertiary butyl ether (MTBE) unit to form MTBE and a butadiene-rich C4 stream. The butadiene-rich C4 stream is selectively hydrogenated in a butadiene unit to form a butene-rich C4 stream. The butene-rich C4 stream undergoes a series of reactions in an isononanol unit to produce isononanol and an olefin-rich stream. The olefin-rich stream is then separate, in a separation unit, a C8, C12, and C16 fuel oil streams.

Abstract: Methods for cracking a hydrocarbon oil include contacting the hydrocarbon oil with a catalyst system in a fluidized catalytic cracking unit to produce light olefins and gasoline fuel. The catalyst system includes a FCC base catalyst and a catalyst additive. The FCC base catalyst includes a Y-zeolite. The catalyst additive includes a framework-substituted *BEA-type zeolite. The framework-substituted *BEA-type zeolite has a modified *BEA framework. The modified *BEA framework is a *BEA aluminosilicate framework modified by substituting a portion of framework aluminum atoms of the *BEA aluminosilicate framework with beta-zeolite Al-substitution atoms selected from titanium atoms, zirconium atoms, hafnium atoms, and combinations thereof. The FCC base catalyst may include a framework-substituted ultra-stable Y (USY)-zeolite as the Y-zeolite. The framework-substituted USY-zeolite has USY aluminosilicate framework modified by substituting a portion of framework aluminum atoms with titanium atoms, zirconium atoms, hafnium atoms, or combinations thereof.

Abstract: Methods are provided for treatment of kerosene/jet fuel boiling range fractions, such as previously qualified jet fuel fractions, to allow blending of the kerosene/jet fuel boiling range fractions to produce a jet fuel boiling range blend having a breakpoint that is equal to or greater than the breakpoint of at least one of the kerosene jet fuel boiling range fractions used to form the blend. The breakpoint of the jet fuel boiling range blend can be maintained by treating at least one of the component fractions of the blend and/or by treating the blend to reduce a nitrogen content. The reduced nitrogen content can correspond to a reduced content of total nitrogen and/or a reduced content of unexpected nitrogen compounds.

Abstract: Low sulfur fuel oil blend compositions and methods of making such blend compositions to increase the stability and compatibility of LSFO blends having paraffinic resids that are blended with distillates and/or cracked stocks of higher asphaltenes and/or aromatics content. In one or more embodiments, distillates and/or cracked stocks that incrementally reduce the initial aromaticity of the distillate or cracked stock with the highest aromaticity are sequentially blended prior to resid addition. Such incremental reduction and sequential blending have been found to provide a resulting low sulfur fuel oil blend that is both compatible and stable.

Abstract: Disclosed is a process for producing mixed xylenes and C9+ hydrocarbons in which an aromatic hydrocarbon feedstock comprising benzene and/or toluene is contacted with an alkylating agent comprising methanol and/or dimethyl ether under alkylation conditions in the presence of an alkylation catalyst to produce an alkylated aromatic product stream comprising the mixed xylenes and C9+ hydrocarbons. The mixed xylenes are subsequently converted to para-xylene, and the C9+ hydrocarbons and its components may be supplied as motor fuels blending components. The alkylation catalyst comprises a molecular sieve having a Constraint Index in the range from greater than zero up to about 3. The molar ratio of aromatic hydrocarbon to alkylating agent is in the range of greater than 1:1 to less than 4:1.
