TL;DR: In this article, lignin-based pitch extracted from black liquor was used as the precursor for synthesis of activated carbon (AC) with high specific surface area and pore volume through chemical activation with potassium hydroxide (KOH).

TL;DR: HSESG exhibits higher efficiency in suppressing wood stack fires than that of ordinary dry water (DW) and ABC dry powder and exhibits excellent environmental friendliness and non-toxicity, which will make it have the potential to develop a new application market.

TL;DR: In this paper, a preparation method and application of nitrogen-sulfur co-doped waste biomass activated carbon is described, where the preparation method comprises the following steps: (1) pretreating crop straws with an activating agent FeCl2 or FeCl3, activating and calcining in an inert gas atmosphere, cooling to room temperature after calcining is finished, and carrying out post-treatment to obtain straw-based activated carbon.

TL;DR: In this article, a preparation method of a dry water material based on silica gel and application of the dry water as a fire extinguishing agent is described, which is more stable, storage time is longer, transportation is convenient, and the material has good fire- extinguishing performance.
