The invention relates to a synthetic route of a hydrocarbon fuel with high density and high volumetric calorific value by using a lignocelluloses-based platform chemical compound as a raw material and completely independent of fossil energy. A liquid fuel obtained by the method can be used in various aircrafts or used as an additive to raise combustion performance of aviation fuel. The method is divided into two parts: 1) under the promotion action of an acid/base catalyst, cyclopentanone (furfural selective hydrogenation product) is subjected to an aldol self-condensation reaction to synthesize unsaturated organic compounds with C10 and C15 polycyclic structures; and 2) a metal loaded A/X catalyst is used to carry out a one-step hydrodeoxygenation and hydrogenation reaction on products generated from the step 1 under low-temperature solvent-free conditions, so as to obtain polycyclic hydrocarbon fuel with carbon number being 10 and 15. The liquid fuel has high density (C10: 0.92g/cm<3>; C15: 1.12g/cm<3>), can be used to effectively raise carrying energy of an aircraft and reduce fuel consumption rate, and meets requirements of high navigational speed, large load and long range.

A particulate filter particularly suited for analytical gravimetric weighing applications is disclosed. The particulate filter includes a polytetrafluoroethylene (PTFE) media supported by a ring and yields stable microgram and submicrogram weighing results. The support ring may be PTFE, metal foil, or another non-hygroscopic polymer such that the mass of the filter does not vary with changes in atmospheric moisture.
