Abstract: A plastic catalytic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The catalytic product stream is quenched to below catalytic pyrolysis temperature quickly after exiting the reactor or bulk separation from the catalyst. Quench preserves selectivity of light olefinic monomers. The catalytic pyrolysis process can be operated in a single stage or a two-stage process.

Abstract: Systems and processes for removing sulfur compounds from a hydrocarbon stream. Sulfur compounds are extracted from a hydrocarbon feed stream with a caustic stream to provide a treated hydrocarbon stream and a rich caustic stream. The sulfur compounds in the rich caustic stream are oxidized in the presence of a catalyst to provide a lean caustic stream. The lean caustic stream is returned to extract sulfur from the hydrocarbon stream. Data such as a concentration of sulfurs species and degree of caustic saturation with the sulfur species in the rich caustic stream may be provided by a sensor, compared against other real-time or historical data and used to provide a recommended adjustment to process conditions associated with an extraction unit, or an oxidation unit, or both.

Abstract: A plastic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The plastic feed is pyrolyzed at a low-temperature pyrolysis process and subsequently pyrolyzed in a high-temperature pyrolysis process directly to monomers, such as ethylene and propylene. Insufficiently pyrolyzed product from the low-temperature pyrolysis process can be fed to the high-temperature pyrolysis process while preserving the desired low-temperature product monomers.

Abstract: Processes for producing biomonomers and precursors for same. A furoate carboxylation reaction is conducted with particles formed from furoates and an alkali base and optionally a reaction promoter. The particles may be in a slurry. The parties are exposed to gaseous carbon dioxide and heated. The reaction produces dicarboxylates which can be separated and used to produce biomonomers like furan dicarboxylate methyl ester and furan dicarboxylic acid.

Abstract: A plastic catalytic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The plastic feed is catalytically pyrolyzed at high silica-to-alumina ratios and elevated temperature to produce high ratios of gas to liquid which results in high light olefin monomer selectivity. The catalytic pyrolysis process can be operated in a single stage or a two-stage process.

Abstract: Processes for producing biomonomers and precursors for same with a slurry-phase reaction. A furoate carboxylation reaction is conducted within a hydrocarbon slurry which includes carbon dioxide. The reaction produces dicarboxylates which can be separated from the slurry and used to produce biomonomers like furan dicarboxylate methyl ester and furan dicarboxylic acid.

Abstract: Processes for producing biomonomers and precursors for producing same. A carboxylation reaction is conducted between an aromatic hydrocarbon, such as a furoate, and a dicarboxylated alkali salt. The reaction produces a carboxylated aromatic hydrocarbon and a decarboxylated alkali salt. The carboxylated aromatic hydrocarbon can be separated and used to produce biomonomers like furan dicarboxylate methyl ester and furan dicarboxylic acid. The decarboxylated alkali salt may be regenerated.

Abstract: A high-temperature plastic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The plastic feed is pyrolyzed at a high temperature of about 600 to about 900° C. directly to monomers, such as ethylene and propylene. During pyrolysis, the plastic feed is contacted with a diluent gas stream at a mole ratio of carbon feed to diluent gas of 0.6 to 20.

Abstract: An integrated process for making furan-2,5-dicarboxylic acid (FDCA) and FDCA derivatives combines a furfural oxidation reaction, an intermediate water removal step, and a furoate salt carboxylation reaction. A furfural feed stream is oxidized with an alkaline solution in the presence of a catalyst and excess base with air as the oxidant. The resulting furoate solution from the first process step is dried to remove water. The anhydrous solid products are sent to a carboxylation process to produce FDCA salt, which can optionally be further reacted to form FDCA or FDCA ester.
