NHD yog ib yam tshiab uas muaj txiaj ntsig zoo de-sulfurizing thiab de-carbonating hnyav nrog siab purity, zoo heev chemistry & tshav kub stability rau xov xwm ntawm siab acidity, alkality thiab kub. Nws yog tsim rau purification ntawm anthraco-synthetic gas. Nws tuaj yeem de-sulfurize cov vulcanized hydrogen tawm ntawm cov kua qaub ntawm cov pa roj carbon monoxide, cov roj av, cov pa roj hauv cov chaw ua haujlwm lossis cov nroog thiab cov roj liquefied roj av. Hauv particular, nws muaj peev xwm de-sulfurize organic sulfur zoo.
