The author participated national research campaign for butadiene rubber

organized by the state of China during 1965—1975

and directly worked on the research and development of the fluidized bed reactor used for producing butadiene through oxidative dehydrogenation of butane. In this paper

the author recollects several representative research and development experiences

such as the work on gas-solid fluidized bed with baffles

the comparison between single fluidized bed reactor and double fluidized bed reactor

the 3000 h catalyst life test

the work at JinZhou medium-scale test base

and the construction of medium-scale fluidized bed reactor at Beijing Shengli Chemical Factory. From these

the author deeply felt the outstanding quality of the Chinese nation’s self-reliance

hard work

and the determination and ability of the Chinese nation to stand in the nations of the world. The author also deeply felt that the superiority of China’s socialist system in concentrating on doing great projects.
