Abstract: A revert alloy is used in the manufacture of a target alloy having a different composition. The weight percent of the elemental constituents of this first alloy and a second or target alloy are obtained, and the ratio of the percentage by weight of each elemental constituent in the first alloy to the second alloy is determined. The lowest ratio is used to determine the amount of the first alloy that is melted and the necessary elemental constituents that are added to the melt to produce the desired composition of the target alloy. The melt is solidified to produce the target alloy.

Abstract: In a method for producing high carbon content products from biomass, a biomass oil is added to a cracking reactor vessel. The biomass oil is heated to a temperature ranging from about 100° C. to about 800° C. at a pressure ranging from about vacuum conditions to about 20,700 kPa for a time sufficient to crack the biomass oil. Tar is separated from the cracked biomass oil. The tar is heated to a temperature ranging from about 200° C. to about 1500° C. at a pressure ranging from about vacuum conditions to about 20,700 kPa for a time sufficient to reduce the tar to a high carbon content product containing at least about 50% carbon by weight.
