A method for processing lignin may comprise flowing a lignin composition comprising a lignin polymer and a solvent through a reaction chamber of a continuous flow reactor, the lignin polymer comprising hydroxycinnamic groups bound to a polymeric backbone; flowing ozone through the reaction chamber containing the lignin composition under conditions to maximize oxidative cleavage of the hydroxycinnamic groups to produce one or more types of aromatic monomers while minimizing oxidative cleavage of the polymeric backbone; and collecting the one or more types of aromatic monomers, e.g., by a size-selective membrane separation device.

Continuous process for the ozonolysis of lignin to yield aromatic monomers

A process for the ozonolysis of an alkane may comprise combining an alkane and ozone in a liquid phase medium comprising COunder conditions sufficient to oxidize the alkane to produce one or more non-combustion products. The liquid phase medium may be free of a super acid.

Ozone-facilitated selective oxidation of alkanes in liquid carbon dioxide

Provided is a process for depolymerizing lignin, the process comprising exposing a liquid feed comprising lignin and a solvent to a metal-incorporated solid mesoporous silicate catalyst under conditions sufficient to depolymerize the lignin to produce one or more aromatic monomers.

Depolymerization of lignin using metal incorporated mesoporous silicate catalysts

A method for increasing ozone concentration in a liquid can include: providing a gas having ozone; introducing the ozone-containing gas into a liquid, wherein the liquid and ozone combination has a temperature between about 0.8 and about 1.5 times the critical temperature of ozone; and increasing isothermally, the pressure of the ozone-containing gas above the liquid to about 0.3 to about 5 times the critical pressure of ozone so as to increase the ozone concentration in the liquid. The temperature is expressed in absolute units (Kelvin or Rankin). The method can be used for removing ozone from a gas or for purifying ozone. The liquid having a high ozone concentration can be used for ozonolysis of a substrate.
