Hou Debang was born in 1890 in a peasant family in Minhou, from an early age diligent and studious, standing on the water wheel to drive water, both elbows lie on the horizontal wood, free hands to read, sometimes hang the book on the horizontal wood of the water wheel to read aloud, leaving the good name of "trailer reading".

At the age of 20, he was admitted to the predecessor of Tsinghua University, the Beijing Tsinghua Preparatory School for Studying in the United States. Three years later, with a total score of 1,000 points in ten courses, he studied in the United States at public expense, and received a bachelor's degree from the Massachusetts Institute of Technology and a master's degree and a doctorate degree from Columbia University.

China's alkali chemical industry has entered the world stage

At the beginning of the last century, all the soda ash needed in China depended on imports. In 1921, Hou Debang resolutely returned to serve the motherland. Under his technical guidance, the establishment of Asia's largest alkali plant - Tianjin Tanggu alkali plant, originally, Hou Debang can rely on patents to obtain high remuneration, but unexpectedly, he wrote the world's first alkali monograph "soda ash manufacturing", the mystery of alkali technology was made public.

In 1943, he took the lead in completing the joint alkali production process of continuous production of soda ash and ammonia chloride in the laboratory, that is, the Hou's alkali production method, and China's alkali chemical industry jumped on the world stage.

Hou Debang's contribution does not stop there. In 1957, Hou Debang proposed the idea of taking ammonium bicarbonate by carbonization method. The process is simple and the investment is small, so China's small fertilizer factories bloom everywhere, making China the only country that produces ammonium bicarbonate fertilizer in large quantities. Before oil production increased in the 1970s and the introduction of large fertilizer processes, these small fertilizer plants supported China's fertilizer industry and allowed grain production to catch up with population growth.
