Patent number: 8772557Abstract: 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: GrantFiled: July 26, 2011Date of Patent: July 8, 2014Assignee: UOP LLCInventors: John Qianjun Chen, Mark Blaise Koch

Patent number: 8581013Abstract: The present invention generally relates to a method for producing a naphtha product from a renewable feedstock. The method includes hydrotreating the renewable feedstock to produce a hydrotreating unit heavy fraction that includes n-paraffins, and hydrocracking the hydrotreating unit heavy fraction to produce a hydrocracking unit product that includes the naphtha product. The method also includes separating the naphtha fraction and optionally recycling the hydrocracking unit heavy fraction through the hydrocracking unit. The present invention also relates to a biorenewable naphtha product suitable for use as feed stock for steam crackers and catalytic reforming units, and for use as fuel, or fuel blend stock.Type: GrantFiled: August 2, 2011Date of Patent: November 12, 2013Assignee: Syntroleum CorporationInventors: Ramin Abhari, H.
