Construction of energy ecological cycle theoretical system based on carbon sink
基于碳汇的能源生态循环理论体系构建

摘要

本文以农林固体废弃物为基础材料，提出了构建基于碳汇的生物质能源-电力-化工-碳捕集-环保-土壤固碳-植物固碳-生物质能源的生态循环理论体系，并阐述了构建该理论的机理和依据，同时可联产土壤调理剂、液氨、碳酸氢铵及多元素长效粒状复合氮肥等多种化工和新型肥料产品，即可大幅减少温室气体的排放，消除硫、氮氧化物对环境的污染和破坏，又可实现二氧化碳、硫氧化物和氮氧化物的资源化循环利用；联产的产品可广泛应用于农林草业，提高农产品产量和质量，增加碳汇，经济、社会和生态效益显著，对推进农林废弃物的资源化综合利用，实现碳达峰和碳中和目标具有十分重要的现实意义。

Abstract

This article takes agricultural and forestry solid waste as the basic material and proposes the construction of an ecological cycle theoretical system based on carbon sink for biomass energy, electricity, chemical engineering, carbon capture, environmental protection, soil carbon fixation, plant carbon fixation, and biomass energy. The mechanism and basis for constructing this theory are explained, and various chemical and new fertilizer products such as soil conditioner, liquid ammonia, ammonium bicarbonate, and multi-element long-term granular composite nitrogen fertilizer can be co produced, It can significantly reduce greenhouse gas emissions, eliminate environmental pollution and damage caused by sulfur and nitrogen oxides, and achieve resource recycling of carbon dioxide, sulfur oxides, and nitrogen oxides; The products of co production can be widely used in agriculture, forestry and grass industry, improve the output and quality of agricultural products, increase carbon sinks, and achieve significant economic, social and ecological benefits. It is of great practical significance to promote the comprehensive utilization of agricultural and forestry waste resources, and achieve the goal of carbon peak and carbon neutrality.
