A process for preparing carbon fibrils by contacting a source of carbon with a supported catalyst that includes at least one multivalent transition metal having a size of about 35 to 700 A deposited on an inorganic substrate having a size of up to about 400 microns.

Fibrils

A process for preparing carbon fibrils by contacting a source of carbon with a supported catalyst that includes at least one multivalent transition metal having a size of about to 700 A deposited on an inorganic substrate having a size up to about 400 microns.

Apparatus for the production of carbon fibrils by catalysis and methods thereof

Products containing carbon fibrils having a morphology of vermicular tubes that are free of a continuous thermal carbon overcoat and have graphitic layers, wherein the length of the projection of the graphitic layers on the fibril axis extends along the axis for a distance of at least two fibril diameters. The fibrils are used to form composites, adsorbents and mats.

Carbon fibrils

A volume of carbon fibrils that includes a multiplicity of fibrils having a morphology consisting of vermicular tubes that are free of a continuous thermal carbon overcoat and have graphite layers that are substantially parallel to the fibril axis and a process for preparing such fibrils.

This invention relates to fibrils. It more particularly refers to carbon/graphite fibrils and to an improved process for producing such. Carbon fibrils as used herein means graphitic fibrils having high surface area, high Young's modulus of elasticity and high tensile strength which are grown catalytically from available sources of carbon.
