摘要：
This paper designs a set of pre-treatment steam leaching system for the raw materials according to the cellulose structure characteristics of corn straw，and expounds the design principle of the system and equipment. The corn straw was treated with the designed system and equipment，and the effect of steam leaching was tested and analyzed，the key parameters of corn straw transformation efficiency were calculated. The test results show that the generation rates of acetic acid and furfural in corn straw after pretreatment are 13.2% and 11.2% ，respectively. The degradation rates of cellulose and hemicellulose are 89.00% and 95.20% ，respectively. In addition，the scanning electron microscope and infrared spectroscopy comparison analysis with straw carbon powder show that the characteristic absorption peaks of lignin are 1600 cm- 1 and 1510 cm- 1 did not change significantly，indicating that the structure of lignin was not obviously destroyed and was similar to that of straw carbon powder. © 2024 Science Press.
