Cellulose is a renewable resource that can be used to develop sorbents for dry flue gas desulphurisation processes. In this study, nanoparticles of hydrated lime (Ca(OH)2) were impregnated onto cellulose nanocrystals (CNCs) using a coprecipitation technique. The Ca(OH)2/CNCs composite was then mixed with diatomite and hydrated. Fourier transform infrared and Xray diffraction confirmed the ...

Effects of ball milling on biochar's physicochemical Increase of surface area. The specific surface area of the BMbiochars were all greater than that of their precursors (corresponding unmilled biochars, Table 1).The unmilled biochars produced at 300 °C had very low surface area (02 m 2 /g), which is common for biochars produced at low temperatures (Guo and Chen, 2014).

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Abstract. Biochar has been recognized as a promising sustainable adsorbent for removing pollutants from wastewater. In this study, two natural minerals, attapulgite (ATP) and diatomite (DE) were coball milled with sawdust biochar (pyrolyzed at 600 °C for 2 h) at ratios of 1040% (w/w) and examined the ability of methylene blue () to be removed from aqueous solutions by them.
