  • Publication number: 20230339838
    Abstract: The present disclosure relates to a process for producing levulinic acid from the technical lignin. The technical lignin is rich in lignin and ash and do not have any other use and usually incinerated as a waste management strategy. During the incineration process, the cellulose also gets burnt and wasted.

  • Patent number: 11623937
    Abstract: An integrated approach for utilizing waste products of 2G bio-refineries to fractionate the lignin of high purity. The present invention also provides a method of recycling of two waste products (2-G ethanol residue as the substrate (LRBR) and fusel oil/synthetic fusel oil (SFO) as one of the solvent) of the biorefineries in a beneficial manner to fractionate the lignin of high purity. The present method of separating high purity lignin comprises fractioning extractive-free lignin rich residue with a solvent, wherein the solvent is a mixture of SFO/Fusel oil and Formic acid. An optimized ratio of waste fusel oil and formic acid gave more than >85% yields of high purity lignin.

  • Publication number: 20190004932
    Abstract: A unit test and automation framework (UTAF) system and method are disclosed for unit testing. A unit definition file that includes properties of the unit being tested may be compiled to generate a skeleton code that describes a structure of the unit and the interactions of the unit with other units. One or more interactions may be overridden to generate a unit production code for the unit. A unit testing (UT) engine may enable interactions between the unit and the other units to run test cases on the unit production code as part of unit testing. Various components of the UTAF system may provide commands to or perform functions for the UT engine to perform the unit testing, such as providing test commands, displaying statistics, providing interface messaging between the unit and the plurality of other units, provide commands for record and replay testing, and other information.
