Latest Patents

One of Liang's latest patents is a "Method and apparatus for torrefaction of biomass materials." This invention provides exemplary techniques that include a heat transfer element designed for use in a rotary furnace. The heat transfer element is constructed from a rounded object with a specific gravity that is substantially higher than that of the biomass material being torrefied. It possesses a heat capacity sufficient to heat the biomass material and a hardness that allows it to function as grinding media for particle size reduction. The design includes surface features that enhance traction between the heat transfer elements and the biomass material. Additionally, a system for torrefaction and particle size reduction of biomass material is discussed, which incorporates this innovative rotary furnace.

Another significant patent is the "Method for the production of an asymmetric hollow fiber membrane." This invention outlines a process for creating a poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) asymmetric hollow fiber membrane. The method involves preparing a dope solution of PVDF-HFP with an additive such as lithium chloride or glycerol, dissolved in a solvent like N-methylpyrollidone (NMP). The dope solution is then spun to form the desired membrane.
