Abstract:
A micro-channel reaction apparatus includes a first mixing device and a first jetting device. The first mixing device includes a first inflow channel and a second inflow channel respectively used to direct a first fluid and a second fluid into the micro-channel reaction apparatus. The first jetting device includes a first tapering portion and a first flared portion, wherein one end of the first tapering portion is connected to the first inflow channel and the second inflow channel; another end of the first tapering portion is connected to the first flared portion; and the first tapering portion has a contract ratio of inner diameter ranging from 0.1 to 0.75.
Abstract:
An oxidation catalyst includes a nickel-containing material, a manganese-containing material and a bromine-containing material, wherein the molar number of the element bromine (Br) in the oxidation catalyst to the total molar number of the element nickel (Ni) and the element manganese (Mn) in the oxidation catalyst substantially ranges from 0.01 to 7.5.
Abstract:
A method for preparing a phenol-formaldehyde resin is provided. The method includes extracting a biomass pyrolysis oil to obtain a first phenolic mixture, mixing the first phenolic mixture, furfural and an alkaline catalyst to proceed to a first polymerization reaction to form a phenol-formaldehyde resin precursor solution, and adding the alkaline catalyst to the phenol-formaldehyde resin precursor solution to proceed to a second polymerization reaction to form a phenol-formaldehyde resin solution. The disclosure also provides a resin material prepared from the phenol-formaldehyde resin. The disclosure further provides a method for preparing a resin molding material.
Abstract:
Method for purifying a crude of 2,5-furandicarboxylic acid (cFDCA) by crystallization is provided. The method includes (a) mixing the cFDCA and a solvent to form a mixture, wherein the solvent has a dipole moment of 3.7D (Debye) to 4.1D; (b) heating the mixture; (c) after step (b), cooling the mixture to precipitate a solid; and (d1) after step (c), filtering the mixture to collect a wet filter cake of the solid, and drying the wet filter cake to obtain purified FDCA. The purified FDCA has a higher FDCA purity than that of the cFDCA.
