摘要： A method of producing biofuels, based on pyrolysis of biomass from macrophytes, includes: pre-treatment of biomass, including processes of drying and crushing the biomass, followed by injection of pre-treated biomass into a pyrolysis reactor; biomass pyrolysis in pyrolysis reactor; a first separation of products; a second separation of products; a third separation of products; burning or collecting gases, wherein the method produces at least four different types of products, including: biochar, pyroligneous extract, vegetable tar and synthesis gas; whereby, the biochar product is collected in the first product separation through the use of a cyclone, the pyroligneous extract product is collected in the second product separation through the use of a condenser, the vegetable tar product is collected in the third product separation through the use of a centrifuge, and the synthesis gas product is collected in the gas burning or collecting step.

摘要： A process for the preparation of an excellent mesophase pitch suitable for use as a spinning pitch for the production of high performance carbon fibers is disclosed. The mesophase pitch can satisfy the four remarkable characteristics at the same time, i.e., a softening point of below 320.degree. C. as determined by Mettler method, a mesophase content of above 90% as examined on a polarized microscope, a quinoline insoluble content of less than 20%, and a xylene soluble content of less than 20%. The mesophase pitch is particularly homogeneous and is easily spinnable. The process can be characterized by a preliminary extraction step, a continuous heat treatment step, and an extraction step. In some cases, the preliminary extraction step can be omitted. Graphite fibers having a tensile strength of about 400 Kg/mm.sup.2 and a modulus of elasticity of above 60 ton/mm.sup.2 can be obtained from the mesophase pitch. Further, even carbon fibers prepared at a carbonization temperature of 1000.degree. C. have a tensile strength of about 300 Kg/mm.sup.2.

摘要： Until now, it has not yet been succeeded to prepare high performance carbon fibers having satisfactory strength from heavy oils of coal or petroleum origin. We now succeeded to prepare an excellent intermediate pitch which allows the preparation of high performance carbon fibers having tensile strength of higher than 300 Kg/mm.sup.2 and Young's modulus of 50 ton/mm.sup.2.The intermediate pitch can be obtained by heating a heavy oil of coal or petroleum origin in a tubular heater under a specific conditions, and then flash distilling the heater effluent in a flash distillation column under a specific condition so as to remove lighter fractions and recovering heavy fraction from the column bottom as the intermediate pitch. The process for the preparation of the intermediate pitch is simple and economical and allows continuous production without fluctuation of quality of the intermediate pitch. The intermediate pitch is also suitable for the production of higher density carbon products.
