Methods and systems for removing or reducing water and producing epoxide. The methods may include providing a first mixture that includes t-butyl hydroperoxide, t-butyl alcohol, and a first amount of water; and contacting at least a portion of the first mixture with a membrane to reduce the amount of water in the first mixture.

Systems and methods for removing or reducing water in mixtures that include t-butyl hydroperoxide

Methods of depolymerizing polyolefin-based material into useful petrochemical products using supported metal oxides and heat are described. The supported metal oxides improve the depolymerization reaction by decreasing the half time for the depolymerization, which results in a higher depolymerization rate and a shorter residence time in the depolymerization unit, allowing for a predictable depolymerization reaction, and decreasing the branching or aromatic formations in the product.

Supported metal oxides as depolymerization catalysts

Methods of depolymerizing polyolefin-based material into useful petrochemical products using metal oxides and heat are described. The metal oxides improve the depolymerization reaction by decreasing the onset temperature for the depolymerization, which results in a higher depolymerization rate and a shorter residence time in the depolymerization unit, allowing for a predictable depolymerization reaction, and decreasing the branching or aromatic formations in the product.

Polyolefin depolymerization with metal oxides

A process of producing allyl alcohol by reacting glycerin with ReO&#x2014;AlOin the presence of gamma-valerolactone (GVL) in a reactor is described. More specifically, a process to produce allyl alcohol, comprising the step of: a) reacting glycerin with ReO&#x2014;AlOin the presence of an inert solvent, GVL, in a reactor, and b) collecting the product comprising allyl alcohol.

Glycerin-only reaction for allyl alcohol production

A method of depolymerizing plastics using a halloysite catalyst is described herein. The method reduces the energy required for the depolymerization process while achieving improved depolymerization results.

Methods of drying streams that include propylene oxide. The methods may include contacting a stream that includes propylene oxide with molecular sieves. The molecular sieves may be in a drying unit, and may be regenerated. The streams that include propylene oxide may include one or more other organic compounds.

Methods of drying propylene oxide

A method including hydroformylating, with syngas, allyl alcohol in an allyl alcohol feed, to produce a hydroformylation product comprising 4-hydroxybutyraldehyde and 3-hydroxy-2-methylpropionaldehyde; and producing a 1,4-butanediol (BDO) product comprising BDO and 1,3-methylpropanediol via hydrogenation of at least a portion of the hydroformylation product. A method including hydroformylating, with syngas, allyl alcohol in a feed comprising bio-allyl alcohol, to produce a hydroformylation product comprising 4-hydroxybutyraldehyde and 3-hydroxy-2-methylpropionaldehyde; and producing a BDO product comprising BDO and 1,3-methylpropanediol via hydrogenation of at least a portion of the hydroformylation product. A method including hydroformylating, with syngas, bio-allyl alcohol in a feed comprising bio-allyl alcohol, to produce a hydroformylation product comprising 4-hydroxybutyraldehyde and 3-hydroxy-2-methylpropionaldehyde; producing a BDO product comprising BDO and 1,3-methylpropanediol via hydrogenation of at least a portion of the hydroformylation product; and removing a byproduct of the production of the bio-allyl alcohol prior to hydroformylating the bio-allyl alcohol and/or from the BDO-product.
