摘要:

为了更好地利用菌渣制备稳定、优质的生物炭,以12种不同原料配方工厂化杏鲍菇菌渣为材料,建立高温裂解生物炭制备工艺,利用孔雀石绿吸附能力对生物炭进行快速质量评价。12种菌渣理化性质表现出一定差异。以X0组菌渣为材料,12种处理炭得率为26.00%~47.17%,且随着温度升高而降低。综合炭得率、孔雀石绿吸附率和能耗,确定400℃、2.5 h为菌渣生物炭最适制备条件。以该条件制备的11种菌渣生物炭各组间炭得率无显著差异,对400 mg/L孔雀石绿2 h吸附率均达到95%以上,表明具有良好的孔隙度和吸附效果。本研究建立了一种菌渣生物炭制备工艺和评价方法,为工厂化菌渣生物炭化利用提供理论和实践依据。

Abstract:

The purpose of this study is to make better use of the spent mushroom substrate (SMS) to prepare stable and high-quality biochar. 12 kinds of SMS of industrial Pleurotus eryngii with different raw material formulae were used as materials to establish the biochar preparation process of pyrolysis method, and the adsorption capacity of malachite green was used for rapid quality evaluation of biochar. The results showed that the physicochemical properties of the 12 kinds of SMS showed some differences. The carbon yield of the 12 treatments using the X0 group of SMS as the material ranged from 26.00% to 47.17%, and decreased with temperature increase. The optimal preparation condition for SMS biochar was determined to be 400℃ and 2.5 h based on the carbon yield, malachite green adsorption rate and energy consumption. The carbon yields of the other 11 kinds of SMS under the optimal condition showed no significant difference, and the adsorption rates to malachite green at 400 mg/L reached more than 95% for 2 h. It indicated that the produced biochar had good porosity and adsorption effect. In this study, the preparation process and evaluation method of SMS biochar were established, which could provide theoretical and practical basis for utilizing biochar prepared from SMS of industrial Pleurotus eryngii.
