利用固定床反应器，以固体酸为催化剂催化桐油预酯化反应。
Pre-esterification of China wood oil catalyzed by solid acid in fixed bed reactor was researched.
固体颗粒在两个流化床层之间循环，使得大型反应器中产生的或需供给的大量热量有传递的可能。
The circulation of solids between two fluidized beds makes it possible to transport the vast quantities of heat produced or needed in large reactors.
总结了固体生物质热解液化装置——一套循环流化床反应器冷态实验的结果。
This study work illustrated briefly the fluidization characteristics of a CFB reactor, which is designed for the biomass fast pyrolysis.
结果表明：反应器内固含率要高于进料中的固体含量；床层轴向压降保持不变，但受固相含量影响；
The results showed that the solid holdup in the reactor was higher than that in feed, the pressure drop remained unchanged along the axial bed but was influenced by the content of solid in feed;
