Professor Lu Ding's research lab specializes in the clean and efficient conversion of coal and biomass, with a focus on co-pyrolysis and co-gasification processes. The lab investigates the role of biomass-derived additives—particularly biomass ash and hydrochar—in enhancing char reactivity, optimizing product distribution, and modifying the physicochemical properties of coal-derived char. Key research directions include the kinetic analysis of gasification behavior, the evolution of alkali and alkaline earth metals (AAEMs), and the structural transformation of carbon during thermal conversion. The lab aims to develop sustainable strategies for synergistic utilization of low-rank coal and biomass.

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
