摘要：
A composition of matter suitable for increasing the viscosity of liquids comprises tendrillar carbonaceous material (TCM) having a ultra low bulk density of less than about 01 g/cm 3 and comprises intertwined tendrils having a diameter (number average) of from about 0.05 to about 0.2 micron and a length (number average) to diameter (number average) ratio greater than about 10, the tendrils comprising carbon fibers and an iron metal component dispersed throughout the carbon fibers as nodules that are intimately associated with and at least partially bonded to the carbon fibers, the tendrillar carbonaceous material comprising from about 0.1 to about 5% by weight iron. The TCM can be used as a viscosifier and for suspending solids in such applications as drilling muds, lubricating oils and greases. The TCM can be prepared by disproportionating carbon monoxide in the presence of iron contained in a blend of (1) previously formed TCM and (2) iron containing particles.
