Publication number: 20140287110Abstract: Apparatus and process for removing and/or converting contaminants in water-miscible organic solvent mixtures by surface interaction effects to forms less objectionable with lesser metabolic impacts for humans. The process both changes distillation entrapped contaminant compounds in-situ and effects removal of the compounds and their reaction products. In what follows, water-miscible-organic-solvent and water mixtures can be substituted for alcohols. The alcohol to be treated is placed in a ventilated vessel leaving room for head space. Contaminant free air or a specific organic-contaminant-free gas is injected into or otherwise placed in contact with the alcohol. A vacuum is pulled within the vessel, which draws the gas through the alcohol into the head space creating gas bubbles. Energy within a specified range of frequencies is imparted to the fluid causing cavitation and reaction.Type: ApplicationFiled: March 14, 2014Publication date: September 25, 2014Applicant: Persedo LLCInventors: Benjamin Mosier, Greg George

Publication number: 20140250773Abstract: Processes are disclosed that achieve a high conversion of lignin to aromatic hydrocarbons, and that may be carried out without the addition of a base. Depolymerization and deoxygenation, the desired lignin convention steps to yield aromatic hydrocarbons, are carried by contacting a mixture of lignin and a solvent (e.g., a lignin slurry) with hydrogen in the presence of a catalyst. A preferred solvent is a hydrogen transfer solvent such as a single-ring or fused-ring aromatic compound that beneficially facilitates depolymerization and hinders coke formation. These advantages result in favorable overall process economics for obtaining fuel components and/or chemicals from renewable sources.Type: ApplicationFiled: May 22, 2014Publication date: September 11, 2014Applicant: UOP LLCInventors: John Qianjun Chen, Mark Blaise Koch
