论文摘要
本文研究了各种因素对核桃壳，杏仁，甲烷，天然气和丙烷丁烷馏分的纳米碳合成的影响，还检查了所获得的纳米碳的质地和吸附特性。在差异反应堆条件下研究了含有（CuO）X*（CUO）X*（CUO）X*（COO）Y*（NIO）Z*（NIO）Z*（NIO）Z*（FE2O3）M/HSZ，用于实施过程。样品的形态组成是通过在配备了一部分能量分散X射线微分析的LEO EVO 50 HVP仪器上扫描电子显微镜进行的。在20 kV的工作距离为10 mm的工作距离记录了能量分散的X射线光谱。通过JEM-2000 CX设备上发光的电子显微镜的方法研究了样品的显微结构。使用BET方法，测量了碳纳米管的特定表面积。计算了材料孔隙率的统计和形态特征。比表面积为168.7平方米，比孔体积为0.456 cm3/g，平均孔直径为2.58 nm。在核桃壳的情况下，在1376 cm-1和1064 cm-1处观察到这种吸收带。在基于惰性氮气气氛中各种温度下的红外光谱中的杏核检查样品时，可以看出，纤维素和木质素的特征是强烈的吸收带，并且治疗随温度升高而降低。
In this article studied the influence of various factors on the synthesis of nano carbons from walnut shells, apricot kernels, methane, natural gas and propane-butane fractions, and also checked the textural and sorption characteristics of the obtained nanocarbon. The catalytic activity of a catalyst containing (CuO)x*(CoO)y*(NiO)z*(Fe2O3)k*(MoO3)m/HSZ prepared based on "sol-gel" technology for the implementation of processes was studied under differential reactor conditions. The morphological composition of the samples was performed by scanning electron microscopy on an LEO EVO 50 HVP instrument equipped with a part of energy dispersive X-ray microanalysis. Energy-dispersive X-ray spectra were recorded at a working distance of 10 mm at 20 kV. The microstructure of the samples was investigated by the method of a glowing electron microscope on a Jem-2000 CX device. Using the BET method, the specific surface area of the carbon nanotubes was measured. Statistical and morphological characteristics of material porosity were calculated. The specific surface area is 168.7 m2/g, the specific pore volume is 0.456 cm3/g, and the average hole diameter is 2.58 nm. In the case of walnut shells, this absorption band was observed at 1376 cm-1 and 1064 cm-1. When examining samples based on apricot kernels in the infrared spectrum at various temperatures in an inert nitrogen atmosphere, it can be seen that cellulose and lignin are characterized by a strong absorption band, and the treatment decreases with increasing temperature.
