2-Steps KOH activation of rice straw: An efficient method for preparing high-performance activated carbons
Abstract
Effects of both pre-treatment and number of steps in KOH activation of raw rice straw (RS) on textural and adsorption properties of RS-derived activated carbons (ACs) were investigated. Three pre-treatment protocols were tested: mechanical, chemical by NaOH pulping, and a combination of both. Activation of RS-based materials was investigated, at a constant temperature of 800 degrees C, according to two ways: a 1-step simultaneous carbonisation-activation with KOH, and a 2-steps process: carbonisation followed by activation by KOH. 2-Steps KOH activation was more efficient in producing activated carbons with high surface areas and high methylene blue adsorption than 1-step KOH activation. Additionally, 2-steps KOH activation increased the yield of activated carbons having moderate ash content (8-14%). Surface areas as high as 1917 m(2)/g were obtained when the combined mechanical-chemical pre-treatment method and a 2-steps activation process were carried out.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
