Abstract:
A method for the manufacture of a metal-containing carbon-fibril-forming catalyst comprising incorporating an effective amount of a carboxylate into a metal-containing carbon-fibril-forming catalyst to enhance the amount of carbon fibrils produced per weight catalyst used in a gas synthesis fibril-forming process compared with the amount of fibrils which would have been produced by said gas synthesis fibril-forming process per weight of said catalyst made without said incorporation of said carboxylate, wherein said metal-containing carbon-fibril-forming catalyst comprises at least one carbon-fibril-forming catalyst metal derived from a metal-containing compound, said metal-containing compound being different from the carboxylate and also being different from a compound from which the carboxylate is derived, said carbon-fibril-forming catalyst metal being selected from the group consisting of Group VI, Group VII and the lanthanides, said carboxylate comprising an anion of a water soluble carboxylic acid.
