| Abstract: |
| China’s annual output of corn stalks ranks first in the world, with a wide range of sources and
high yield. Anaerobic digestion and gas production is one of the important ways to efficiently use corn stover.
The main components of corn stalk include cellulose, hemicellulose and lignin. Its complex three-dimensional
network structure has great hindrance to its anaerobic fermentation, leading to problems such as long production
cycle, low gas production and low biodegradation rate. In order to improve the digestibility of corn stalks, it
is necessary to efficiently destroy the compact structure through a certain pretreatment technology, thereby
improving the biorecyclability of corn stalks. At present, the pretreatment methods of straw include physical
pretreatment, chemical pretreatment, biological pretreatment and combined pretreatment methods. Based on a
brief introduction to the main components and contents of corn stalks, this paper summarizes the current corn stalk
joint pretreatment method and analyzes its effect on anaerobic digestion and gas production of corn stalks. |
