Abstract

The solid residue of Japanese citron after its compression to obtain juice and then the extraction of oil was used as the raw material of activated carbon in order to substantiate the cascading use of Citrease for several high value products. Most of the inorganic compounds in the carbonized samples were K₄H₂(CO₃)₃·1.5 H₂O and CaCO₃. Although the amount of these inorganic compounds was independent of the carbonization temperature, most of these inorganic compounds were removed by the KOH activation process. The BET specific surface area of the sample after the KOH activation increased with the increasing amount of KOH added for activation, and the value was greater than 1900 m² g⁻¹ when the amount of KOH was greater than 67 wt%. The pore sizes and pore volumes were calculated by several methods, such as the Langmuir, t method, αs method, MP method, BJH method, and INNES method, in order to analyze in detail the surface condition related to the pores. The capacitance value of the sample activated at KOH 75 wt% was 157 F g⁻¹ at 1 mV s⁻¹.

微波萃取提取日本香solid固体残渣的KOH活化及其作为EDLC电极的性能

摘要

将日本柚子压缩后得到的固体残余物获得汁液，然后提取油被用作活性炭的原料，以证实柠檬酸酶在多种高价值产品中的级联使用。碳化样品中的大多数无机化合物为K ₄ H ₂（CO ₃）₃ ·1.5 H ₂ O和CaCO ₃。尽管这些无机化合物的量与碳化温度无关，但是大多数这些无机化合物是通过KOH活化过程除去的。KOH活化后样品的BET比表面积随用于活化的KOH的增加而增加，且该值大于1900 m²克^-1时的KOH的量为大于67重量％。孔的大小和孔体积通过Langmuir，t法，αs法，MP法，BJH法和INNES法等几种方法计算，以详细分析与孔有关的表面状况。在KOH 75激活重量％的试样的电容值为157 F G ^-1在1毫伏小号^-1。
