Abstract

This study proposed an innovative process of biomass torrefied liquids washing, torrefaction, and chemical looping gasification (BW/T-CLG). The fixed-bed reactor and Py-GC/MS were used to assess the effects of combined pretreatments on CLG performance of rice straw (RS). The pretreatment results indicate that torrefaction liquids washing effectively removed ash component in the RS, and combined measures clearly enhanced the calorific values and energy density of RS. The jointly pretreated RS exhibits good cyclic stability in multiple chemical looping gasification (CLG) cycles. When the reaction temperature boosted from 700 to 900 °C, a 34 % improvement in carbon conversion efficiency (ηC) and 32.9 % rise in cold gas efficiency (ηG) were achieved. As the OCs proportion increased, the ηC increased from 62 % to 72 %, whereas the CO selectivity (SelCO) and the syngas content (Csyngas) generally reduced, and its optimal value was determined to be 30 %. The Py-GC/MS result showed that both washing and torrefaction decreased the levels of acidic compounds while boosting the production of high-value products.
