Technique optimization of hydrothermal carbonization based on energy yield for Camellia oleifera shells
摘要
Abstract
In this paper, hydrothermal carbonization (HTC) temperature, residence time, and solid ratio for HTC of waste Camellia oleifera shells were analyzed by the higher heating value, and energy yield in order to design and optimize the HTC process of waste Camellia oleifera shells. Based on these, three processing conditions of HTC were optimized by the orthogonal experiment. The results showed that the optimal process conditions were 200 ℃ of HTC temperature, 30 min of residence time, and 10%of solid ratio. Under these conditions, the higher heating value and energy yield were 22.28 MJ/kg and 75.07%, respectively. Thermogravimetric analysis of combustion experiments showed that the combustion process of Came llia ole ife ra shells hydrochar moved to the high temperature zone compared to raw simples. The results could be used to guide the production of Camellia oleifera shells hydrochar for the higher calorific value, higher energy yield and provide references for utilizations of Camellia oleifera shells.关键词
