Publication number: 20210363080Abstract: Processes for producing alcohols from biomass are provided. The processes utilize supercritical methanol to depolymerize biomass with subsequent conversion to a mixture of alcohols. In particular the disclosure relates to continuous processes which produce high yields of alcohols through recycling gases and further employ dual reactor configurations which improve overall alcohol yields. Processes for producing higher ethers and olefins from the so-formed alcohols, through alcohol coupling and subsequent dehydration are also provided. The resulting distillate range ethers and olefins are useful as components in liquid fuels, such as diesel and jet fuel.Type: ApplicationFiled: May 20, 2021Publication date: November 25, 2021Inventors: Peter H.

Patent number: 10870175Abstract: Microfluidic flow-through elements and methods for forming and using the same, particularly, low cost, easily sterilized, disposable microfluidic flow-through elements may include an orifice region suitable, for example, for fluid jet formation (such as in a droplet sorter or flow cell) or sample injection or hydrodynamic focusing (such as in a non-droplet flow cytometer). Laser drilling, for example laser ablation, may be used to form an orifice region extending through an orifice wall section of a base substrate. The base substrate may be unitarily-formed by injection molding a polymeric material. The orifice region may be advantageously configured to form a predetermined geometry by controlling the characteristics of the ablating beam.Type: GrantFiled: September 18, 2014Date of Patent: December 22, 2020Assignee: CYTONOME/ST, LLCInventors: Kristopher Scott Buchanan, Johnathan Charles Sharpe
