A membrane adsorbent was successfully made from palm empty fruit bunches (PEFB), which was pyrolysed as physical activation. The effect of adding the impact of one-step catalyst (hydrochloric acid) and differences in the concentration on the characteristics and structure and deconvolution are investigated in this study. The results of the research have been successfully created and characterised using Fourier-Transform Infrared (FTIR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) isotherm, and membrane morphology using SEM test. Membrane performance testing was carried out using a biogas flame test. The adsorber membrane was made by adding NHCl as a cationic surfactant, polyvinyl acetate (PVA), and polyethylene glycol (PEG) with a ratio of 1:3. The FTIR test has a functional group: O-H; C-H stretch; C=C-C; Arly O-Strech; C-O. Adsorbent membrane with the addition of 0.5 M HCl catalyst had the highest ratio of O-H/C=C-C relative area of 4.33. The diffractogram shows an amorphous structure with (002) and (100) graph planes. Adsorber membrane with a concentration of 1.5 M HCl has formed amorphous structured fibre. The adsorber membrane with a concentration of 0.5 HCl activator gave a surface area of 0.5345 m g and a pore volume of 0.000983 cm g.
一种膜吸附剂由棕榈空果串（PEFB）成功制成，其通过物理活化进行热解。本研究考察了添加一步催化剂（盐酸）的影响以及浓度差异对其特性、结构和解卷积的影响。研究结果已通过傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）、布鲁诺尔-埃米特-泰勒（BET）等温线以及使用扫描电子显微镜（SEM）测试的膜形态进行了成功创建和表征。膜性能测试使用沼气火焰测试进行。吸附剂膜通过添加氯化铵作为阳离子表面活性剂、聚醋酸乙烯酯（PVA）和聚乙二醇（PEG）以1:3的比例制成。FTIR测试显示有官能团：O-H；C-H伸缩振动；C=C-C；芳基O-伸缩振动；C-O。添加0.5 M HCl催化剂的吸附剂膜的O-H/C=C-C相对面积比最高，为4.33。衍射图谱显示为具有（002）和（100）晶面的非晶结构。浓度为1.5 M HCl的吸附剂膜形成了非晶结构纤维。浓度为0.5 M HCl活化剂的吸附剂膜的表面积为0.5345 m²/g，孔体积为0.000983 cm³/g。
