    • 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 0.1 g/cm.sup.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.
    • 适用于提高液体粘度的物质组合物包括具有小于约0.1g / cm 3的超低堆积密度的含毛碳质材料(TCM),并且包括直径(数均)为约0.05至约0.2的交织的卷须 微米和直径(数均)比大于约10的长度(数均),包含碳纤维的卷须和分散在整个碳纤维中的铁金属成分作为与碳密切相关并且至少部分地结合到碳上的结核 纤维,包含约0.1至约5重量%铁的花质碳质材料。 TCM可用作增粘剂,并用于将固体悬浮在钻井泥浆,润滑油和润滑脂等应用中。 在(1)预先形成的TCM和(2)含铁颗粒的共混物中存在的铁存在下,可以通过歧化一氧化碳来制备TCM。
