Abstract: A method for preparing a bio-based composite using palm biomass powder as raw material, which belongs to the technical field of preparation methods for bio-based composites. During palm micropowder washing, 100 parts by weight of 600-1,200 mesh palm micropowder is placed in a reactor, and 400-500 parts by weight of acetone is added to the reactor in a 1:4 or 1:5 bath ratio; during surface treatment of palm micropowder, the reaction system after solvent displacement is heated to 80-100° C., and distillate is dehydrated with a 3A molecular sieve and then refluxed to a reactor; bio-based resin is compounded and extruded. At least one embodiment of the present invention solves the problem that use of palm as a biomass raw material leads to impurity migration and insufficient product performance due to high small oily molecule content.

Abstract: Disclosed herein is a process for preparation of an ultra high molecular weight polyethylene catalyst, comprising: (1) under inert atmosphere, dispersing a magnesium halide in an inert solvent; (2) adding an alcohol to react with the magnesium halide, to form a solution or dispersion of a magnesium halide-alcohol adduct; (3) adding an alkyl aluminum halide to react with the magnesium halide-alcohol adduct, to form an intermediate product; (4) optionally, subjecting the intermediate product to an ultrasonic wave treatment; (5) adding a titanium compound to perform Ti-supporting reaction; (6) optionally, subjecting the reaction mixture from step (5) to an ultrasonic wave treatment; and (7) recovering solid particles, to obtain the ultra high molecular weight polyethylene catalyst, wherein at least one of steps (4) and (6) is present.
