As the technology matures, more data are becoming available and uncertainties decline. The goal of this ex-ante life cycle assessment (LCA) was to provide an outlook of the …
— (1), (2), (3) are endothermic in nature. In order to remove the intermediate products like CO and H 2, the reaction is made exothermic by mixing with oxidizing gases like steam/CO 2 [8].Bergna et al. compared single-stage and two-stage activation processes using biomass (spruce and birch chips) [9].In the single-stage process, the chips were …
— For example, assume that carbon A adsorbs iodine to produce a standardized Iodine Number of 1100 mg/g., and has an A.D. of 0.4 g/cc Carbon B has an Iodine Number of 950 mg/g and an A.D. of 0.5 g/cc. Multiplying the A.D. by the weight basis activity value, carbon A has a volume iodine capacity of 440 mg/cc while carbon B has a …
