Lu Ding教授の研究室では、石炭とバイオマスの共同処理を効率的・クリーンに実現するための熱化学的プロセスに注力しています。特に、バイオマス灰を触媒として用いたコークスのガス化反応性の向上や、ヒドロターマル処理を施したバイオマスと石炭の混合ガス化挙動の解明を進めています。炭素構造やアルカリ金属・ alkaline earth metals (AAEM) の化学的形態の変化と反応性の関係を定量的に評価する独自のアプローチが特徴です。

In this study, two typical biomass ash additives, rice straw ash (RSA), high K and high Si and cotton stalk ash (CSA, high K–Ca–Na and low Si), were adopted as natural and effective catalysts to systematically investigate the influence of biomass ash type on pyrolysis product distribution, char physicochemical characteristics (i.e., chemical forms and concentrations of alkaline and alkaline earth metals (AAEMs), pore structure, and carbon structure), and char gasification reactivity of bituminou
Co-gasification of biomass after hydrothermal treatment (HTT) and coal blends had great potential to realize the clean and efficient co-conversion of biomass and coal. In this study, co-gasification reactivity and synergy of Shenfu bituminous coal and rice straw (RS) hydrochar (prepared at HTT temperatures of 200, 220, and 240 °C) blends (denoted as SF-RS200, SF-RS220, and SF-RS240) were investigated using a nonisothermal thermogravimetric analysis, and gasification kinetic analysis was conducte
