Process and apparatus for the accelerated densification of a porous carbonaceous substrate by decomposition of a hydrocarbonaceous substance at high temperature and high pressure, and method for the preparation of the said substance

摘要

the present invention is directed to a process and a device for the rapid densification of a porous carbon substrate (9).;this process.the kind that decompose a hydrocarbon material in the presence of the substrate (10) in a closed reactor for the removal of hydrogen released during the reaction.and the walls are flexible enough to be able to work under high pressure.is that the substance is to decompose hydrocarbon selected from the group consisting of pitch, acenaphthylene, phenanthrene, or mixtures thereof.;application to the manufacture of carbon materials with high temperature, compact, high mechanical strength and a high resistance to abrasion.
