在粉状活性炭(PAC)中加入载磷酸废木屑，经挤压、加热等步骤，使 PAC 转化为成型活性炭(ACM)。利用 SEM、XRD、N2吸附-脱附技术及万能试验机，考察了ACM的形貌、微晶结构、比表面积、孔结构及耐压强度。研究发现，载磷酸废木屑制取容易，且能使PAC成型但无损比表面积。当 PAC 用量、加热温度、加热时间分别为40%、560℃、100 min 时，可得到耐压强度为4.2 MPa、比表面积达710 m2/g 的ACM；延长加热时间，能够提高 ACM的比表面积、微孔孔容和耐压强度，但对其微晶结构影响较小。

Powdery active carbon (PAC)was converted into active carbon monoliths (ACMs)by adding H3 PO4-loaded waste sawdust into it,followed by treatments like extrusion and heating.The morphologies,microcrys-tal structures,specific surface areas (SSAs),pore structures,and compression strengths of the obtained ACMs were investigated using SEM,XRD,N2 adsorption-desorption technique,and compression test.The H3 PO4-loaded waste sawdust was an easy-making binder.Moreover,by using it,the PAC was converted into ACMs without reducing its SSA.An ACM with a SSA of 710 m2/g and compression strength of 4.2 MPa could be produced by heating at 560 ℃ for 100 min using a PAC dosage of 40%.The increase in activation time increased the SSA,micropore volume,and compression strength of ACMs,but hardly affected their microcrystal struc-ture.
