WebAbstract High quality impregnating pitch with low quinoline insoluble (QI) content and high coking value (CV) is required during the production of ultrahigh power graphite electrodes and C/C composites. High quality impregnating pitch using medium temperature coal tar pitch as raw material was prepared by a new route. The medium temperature pitch was … WebThe absorption of CO2 by chemical solvents at a low temperature (40-65°C) The recovery of CO2 from chemical solvents by using low-grade heat (a temperature in the range of 100-150°C), usually extracted from power plants.
