PROCESS FOR THE PREPARATION OF AN INTERMEDIATE PITCH FOR MANUFACTURING CARBON PRODUCTS

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/mm2 and Young's modulus of 50 ton/mm2. 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.

PROCESS FOR THE PRODUCTION OF MESOPHASE PITCH FROM ISOTROPIC PITCH

An improved process for producing an anisotropic pitch product suitable for carbon fiber manufacture. A carbonaceous feedstock substantially free of mesophase pitch is heated at elevated temperature while passing an oxidatively reactive sparging gas such as air through the feedstock. The oxidatively treated feedstock, which contains isotropic pitch, is solvent fractionated to recover a solid pitch which on fusion becomes an anisotropic pitch product having from 50 to 100 percent by volume mesophase. In one aspect of the invention the carbonaceous feedstock is oxidatively treated in a melt phase at a lower temperature and the resulting isotropic pitch is then heated at a higher temperature in a melt phase in the presence or absence of a non-oxidative sparging gas prior to solvent fractionation.

METHOD FOR REDUCING THE SURFACE AREA OF CARBONACEOUS POWDERS

The surface area of carbonaceous powders can be reduced by mixing a small amount of petroleum or coal tar pitch with the carbonaceous powder and pyrolyzing the mixture. The carbonaceous powder becomes coated with decomposition products of the pitch and the coating can have substantially lower surface area than the original carbonaceous powder. Small amounts of pyrolyzed pitch are involved and the bulk properties of the carbonaceous powder remain virtually unaffected. The method is particularly suitable for reducing the surface area of carbonaceous anode powders for use in non-aqueous rechargeable lithium ion batteries and thereby improves the safety of the batteries.

Pitch is a viscoelastic polymer that remains after distilling fuel gas and fuel oil from coal or crude oil. When the volatile substances included in the pitch are removed, the mechanical bonding strength is modified into a precursor to obtain valuable industrial materials such as carbon fiber, carbon heat sink, and carbon conductor with excellent physical properties such as thermal conductivity and electrical conductivity. The conventional pitch reformer wastes a lot of energy and manpower by filling pitch into a reforming container, heating it to a high temperature, removing volatile substances, cooling it to a certain temperature, discharging it, opening the container, and refilling the raw pitch to reform it. The specific gravity of pitch increases as volatile substances are removed, and when applied heat is consumed to evaporate volatile substances, a constant evaporation temperature is maintained and the temperature rises when all volatile substances are removed. And when the pitch suddenly comes into contact with a high temperature, it is carbonized and becomes a solid before the volatile material evaporates. Solidified carbon does not melt even at a temperature of 3000 degrees and does not dissolve in solvents such as toluene and quinoline. A reforming means that can greatly save energy and manpower by continuously injecting and reforming the original pitch ...

Process for preparing precursor pitch for carbon fibers

ABSTRACT A precursor pitch for the production of carbon fibers is obtained by heat-treating a carbonaceous pitch in the form of a thin film having a thickness not larger than 5 mm at a temperature in the range of 250° to 390°C and under a reduced pressure not higher than 100 mmHg. By melt-spinning this precursor pitch and subjecting the resultant pitch fiber to infusiblization and carboniza-tion and, if required, to subsequent graphitization, there is obtained a high quality carbon fiber.
