Embodiment Construction
[0019] like figure 1 Shown, the present invention is further illustrated by the following examples.
[0020] Henan Academy of Sciences Energy Research Institute Co., Ltd. designed a biomass-based ethyl levulinate production plant with an annual output of 500t. The biomass is corn stalks as an example.
[0021] 1. Calculation of corn stover production stages
[0022] During the growth of corn stalks, there are energy consumption and carbon dioxide emissions in the process of tillage, fertilization and harvesting, as well as the production of pesticides and fertilizers. Considering that corn stalks are the appendages of grain growth and agricultural waste, the energy consumption and farming , The carbon dioxide emissions produced during fertilization are not included in the production process of corn stalks.
[0023] During the process of using corn stalks as fuel, carbon dioxide increased in a certain period of time. However, with the re-generation of corn stalks, carbon diox...

The invention belongs to the field of energy-oriented utilization of forestry wastes, and relates to a method for evaluating the environmental influence and energy consumption condition caused by analyzing utilization of biomass-based ethyl levulinate as liquid fuel subjectively, quantitatively and comprehensively. The method comprises the steps of: evaluating the environmental influence and energy consumption in the whole process from production of raw materials of ethyl levulinate to utilization of ethyl levulinate according to the life cycle theory of the biomass-based ethyl levulinate. The evaluation method can be used for evaluating and comparing the environmental influence and energy consumption in different stages of the life cycle of the biomass-based ethyl levulinate, and for evaluating and comparing the life cycle, environmental influence and energy consumption of biomass-based ethyl levulinate manufacturing plants of different scales.
Description
technical field [0001] The invention belongs to the field of energy utilization of agricultural and forestry waste, and relates to an evaluation method for objectively, quantitatively and comprehensively analyzing the environmental impact and energy consumption status of using biomass-based ethyl levulinate as a liquid fuel. Background technique [0002] Ethyl levulinate can be mixed with diesel and used as vehicle fuel, which has good combustion performance and can reduce the greenhouse gas CO in the atmosphere 2 , reduce NO X , SO X And the emission of solid particles, it is a clean and efficient fuel. Biomass is a renewable energy source that can be converted into ethyl levulinate using biomass. The traditional view is that biomass is renewable, and biomass-based liquid fuels (such as ethyl levulinate) can achieve zero emissions, which is not conducive to energy saving and emission reduction in the production process, so looking for a bio-based levulinic acid The eval...
