Abstract

The aim of the research was to analyze the electrical conductivity of the obtained coal from organic material by pyrolysis. In order to take measurements of the electrical properties of the biochar, a prototype device was built. In addition to measurements of electrical properties, it enables measurement of the specific density of any sample of bulk material. In the case under consideration, after filling the working chamber and concentrating the powder, a carbon pellet was obtained. For it, direct electrical properties were determined by direct measurements, ie: voltage drop at the current flow through the sample (direct and alternating current), resistance of the carbon resistor, value of current flowing through the resistor, inductance and capacity. In addition, the dynamic characteristics of the voltage with respect to the alternating current flowing through the carbon resistor were recorded using the oscilloscope. It has been noted that capacitive features can be attributed to the test samples.

从能源工厂热解得到的生物炭的电学特性分析

本研究的目的是分析由有机物热解得到的煤的电导率。为了测量生物炭的电学特性，我们制作了一个原型装置。除了测量电性能外，它还可以测量任何散装材料样品的比密度。在考虑的情况下，在填充工作腔并浓缩粉末后，获得碳球团。对于它，直接电学性质是通过直接测量来确定的，即:流过样品的电流(直流电和交流电)时的压降、碳电阻的电阻、流过电阻的电流值、电感和容量。此外，用示波器记录了电压相对于流过碳电阻的交流电的动态特性。已经注意到，电容特性可归因于测试样品。
