Comparative Analysis of Small-Scale Rice Husk Gasification in a Downdraft Reactor and a Novel Self-Bed Bubbling Fluidized-Bed Reactor
In order to improve producer-gas production, this work aims to qualify and compare the products of rice husk gasification in two types of reactors: a downdraft fixed-bed and a self-bed bubbling fluidized-bed (BFB). Herein, comparative experiments were carried out in both reactors, with each capacity of 15 kg-feedstock/h. Equivalence ratio (ER) was defined as the other independent variable. Herein, CO, H 2 , CO 2, and CH 4 contents, carbon conversion efficiency, and cold gas efficiency in an ER of 0.30 for self-bed BFB gasification were 15.67%, 7.41%, 17.84%, 3.071%, 30.19%, and 31.34%, respectively. In contrast, for downdraft gasification with an ER of 0.27, those values were 5.25%, 3.34%, 6.07%, 0.87%, 19.06%, and 17.94%, respectively. Research found that a self-bed BFB gasifier was a promising candidate for a small-scale application. However, further research still needs to be done in order to improve the technical and operational sides of the gasifier
