Processes for producing n-heptane from a mixture of 1-hexene and 1-octene in the presence of a suitable isomerization-metathesis catalyst followed by a hydrogenation step are disclosed. Integrated manufacturing systems for producing n-heptane with minimal waste also are disclosed.

Synthesis of n-heptane from olefins and related production systems

Depolymerization processes and systems for converting polyolefin waste and other waste plastic to hydrocarbons, specifically liquid and gaseous depolymerization reaction products. A depolymerization or catalytic pyrolysis process can be conducted on a process feed which includes a polyolefin waste and a hydrocarbon co-feed under depolymerization conditions, including contacting the reactor feed with a depolymerization catalyst such as a zeolite-based catalyst. The resulting reactor effluent subsequently can be used as feeds or co-feeds for making circular products such as circular ethylene and circular polyethylene.

Catalyzed depolymerization of a chemically complex feedstock

A method comprising a) contacting a solvent, a carboxylic acid, and a peroxide-containing compound to form an acidic mixture wherein a weight ratio of solvent to carboxylic acid in the acidic mixture is from about 1:1 to about 100:1; b) contacting a titanium-containing compound and the acidic mixture to form a solubilized titanium mixture wherein an equivalent molar ratio of titanium-containing compound to carboxylic acid in the solubilized titanium mixture is from about 1:1 to about 1:4 and an equivalent molar ratio of titanium-containing compound to peroxide-containing compound in the solubilized titanium mixture is from about 1:1 to about 1:20; and c) contacting a chromium-silica support comprising from about 0.1 wt. % to about 20 wt. % water and the solubilized titanium mixture to form an addition product and drying the addition product by heating to a temperature in a range of from about 50&#xb0; C. to about 150&#xb0; C. and maintaining the temperature in the range of from about 50&#xb0; C. to about 150&#xb0; C. for a time period of from about 30 minutes to about 6 hours to form a pre-catalyst.

Methods of preparing a catalyst utilizing hydrated reagents

This disclosure provides processes for forming acrylic acid and other &#x3b1;,&#x3b2;-unsaturated carboxylic acids and their salts, including catalytic processes, and catalyst systems for effecting the processes. For example, there is provided a catalyst system for producing an &#x3b1;,&#x3b2;-unsaturated carboxylic acid or a salt thereof, the catalyst system comprising: (a) a transition metal precursor compound comprising a Group 8-11 transition metal and at least one first ligand; (b) optionally, at least one second ligand; and (c) an anionic polyaromatic resin with associated metal cations. The catalyst system can further comprise (d) an olefin; (e) carbon dioxide (CO); and (f) a diluent. Methods of regenerating the anionic polyaromatic resin with associated metal cations are described.

Formation of &#x3b1;,&#x3b2;-unsaturated carboxylic acids and salts thereof from metalalactones and anionic polyelectrolytes

This disclosure provides for catalyst systems and processes for forming an &#x3b1;,&#x3b2;-unsaturated carboxylic acid or a salt thereof. In an aspect, the catalyst system can comprise: a transition metal precursor comprising a Group 8-11 transition metal and at least one first ligand; optionally, at least one second ligand; an olefin; carbon dioxide (CO); a diluent; and an oxoacid anion-substituted polyaromatic resin comprising a sulfonated polyaromatic resin, a phosphonated polyaromatic resin, a sulfinated polyaromatic resin, a thiosulfonated, or a thiosulfinated polyaromatic resin, and further comprising associated metal cations.
