本文研究了灯心草在453-513 K温度范围内的水热炭化过程。柠檬酸浓度为0.2 kg m ~（-3）时没有明显的催化作用。一个动力学模型，建议为底物水解和水热炭的形成，以及副产品保持溶解。具体地，在较高底物浓度下增加水热炭产率可以用中间产物形成水热炭的反应级数1.53来描述。(C)2015爱思唯尔有限公司版权所有。
Hydrothermal carbonization of soft rush (Juncus effusus) has been studied in the temperature range of 453-513 K. Citric acid at the concentration of 0.2 kg m(-3) did not have a significant catalytic effect. A kinetic model is suggested for substrate hydrolysis and the formation of hydrochar as well as byproducts remaining dissolved. Specifically, increasing hydrochar yield at higher substrate concentration can be described with a reaction order of 1.53 for hydrochar formation from intermediate products. (C) 2015 Elsevier Ltd.
