Abstract

The invention provides an oxygen-free steam carbonization method for cotton straws. The method comprises the following steps: cutting the cotton straws into section materials, immersing the cotton straw section materials in an NH4Cl solution, taking out the immersed cotton straw section materials, draining off the section materials, putting the drained-off cotton straw section materials into a container, carrying out steam heating for carbonization, cooling to room temperature, washing and drying, thus obtaining biomass charcoal. The biomass charcoal obtained through the method is large in specific surface area, good in pore structure and high in organic carbon content, and has a good improvement effect when used for soil improvement.

Description

technical field

[0001] The invention belongs to the technical field of resource utilization of agricultural waste, and in particular relates to an oxygen-free steam carbonization method of cotton stalks. Background technique

[0002] Cotton is a very important economic crop. It is also an important industrial raw material. Cotton is widely planted in my country and is the largest cotton producing country in the world. my country's cotton production accounts for more than 1 / 4 of the world's cotton production. While producing cotton, it also produces a large amount of cotton stalk waste. According to statistics, more than 50% of straws in my country are discarded or burned, causing serious waste of resources and environmental pollution. If these abundant waste straws can be effectively utilized, it will not only turn waste into wealth and benefit the people, but also improve the comprehensive economic benefits of cotton planting. In recent years, there have been many researc...
