Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. Particular MOFs may comprise N,N'-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

The present disclosure provides methods and systems for co-processing a hydrocarbon feed in an FCC system with a second feed of a biomass-derived pyrolysis oil and a third feed of a plastic-derived pyrolysis oil and/or lubricant. A method of co-processing fluid catalytic cracking feeds, includes: introducing a hydrocarbon feed to a fluid catalytic cracking reactor, wherein the hydrocarbon feed comprises hydrocarbons; introducing a biomass feed to the fluid catalytic cracking reactor wherein the biomass feed comprises a biomass-derived pyrolysis oil; introducing a waste feed to the fluid catalytic cracking reactor, wherein the waste feed comprises a plastic, a plastic-derived pyrolysis oil, a lubricant, or a combination thereof; and reacting at least the hydrocarbon feed, the biomass feed, and the waste feed in the presence of one or more fluid catalytic cracking catalysts in the fluid catalytic cracking reactor to produce cracked products.

Co-processing of pyrolysis oils, lubricants, and/or plastics

The present disclosure provides base stocks and or diesel fuel, and processes for producing such base stocks and or diesel fuel by polymerizing alpha-olefins and internal olefins. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes: i) introducing, neat or in the presence of a solvent, a feed comprising a branched C-Cinternal olefin, with a catalyst compound comprising a group 8, 9, 10, or 11 transition metal and at least one heteroatom and ii) obtaining a C-Cpolyolefin product having one olefin, a methylene content of from about 1 wt % to about 98 wt %, and or a methyl content of from about 1 wt % to about 75 wt %. The feed may further include a linear C-Cinternal olefin, a C-Calpha-olefin, or a mixture thereof.

Processes for polymerizing alpha-olefins, internal olefins and compositions thereof

The present disclosure provides base stocks and processes for producing such basestocks by polymerizing internal olefins. The present disclosure further provides base stocks, comprising low molecular weight polyolefin products, having one or more of improved flow, low temperature properties, and thickening efficiency. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes introducing a feedstream comprising C-Cinternal-olefins with a catalyst system comprising a nickel diimine catalyst optionally in the presence of a solvent. The method includes obtaining a C-Cpolyolefin product having one or more of a carbon fraction of epsilon-carbons of from about 0.08 to about 0.3, as determined byC NMR spectroscopy, based on the total carbon content of the polyolefin product.
