Embodiment Construction

[0011] After completing the life cycle inventory analysis of various fuels, the fossil fuel consumption in the fuel life cycle and the total energy consumption in the fuel life cycle can be obtained. According to the obtained two index values ​​and the calculation method shown in formula 1, the Fuel life cycle fossil fuel usage (λ) can be calculated. The larger the value of λ, the greater the proportion of fossil fuel consumption in the fuel life cycle to the overall fuel consumption, and the worse the renewable of the fuel; conversely, the smaller the value of λ, the greater the proportion of fossil fuel consumption in the fuel life cycle to the overall fuel consumption. The smaller the fuel, the more renewable it is.

[0012] For example, to compare gasoline and bioethanol fuel, see Table 1 for specific reference data. The data are only used for method instructions and do not necessarily represent current accurate values:

Abstract

The invention discloses a fuel renewable evaluation index, belonging to the fuel evaluation field; by utilizing life cycle fossil fuel consumption index and life cycle integral fuel consumption index, a new fuel renewable evaluation index-life cycle fossil fuel consumption rate (lamda) is formed. The fuel renewable evaluation index is characterized in that: the index is equal to the specific value of the life cycle fossil fuel consumption and the life cycle integral fuel consumption and has no dimension. After life cycle inventory analysis of various fuels is carried out, the fossil fuel consumption in fuel life cycle and total energy consumption value of fuel life cycle can be obtained, according to the two index values, the fossil fuel utilization rate (lamda) in the fuel life cycle can be calculated. The bigger the lamda value is, the proportion that fossil fuel consumption accounts for the fuel life cycle is high, the fuel renewable performance is poor; conversely, the smaller the lamda is, the proportion that fossil fuel consumption accounts for the fuel life cycle is low, and the fuel renewable performance is good.

Description

technical field [0001] The invention belongs to the field of energy renewable evaluation methods, and relates to a fuel renewable evaluation index. Background technique [0002] With the rapid development of society and economy, people's demand for fossil fuels such as coal, natural gas and oil continues to increase. However, the reserves of these fossil fuels are limited and non-renewable. In order to realize the sustainable development of society, we should develop new renewable energy sources and fuels. Therefore, when developing and producing a new fuel, it becomes very important to evaluate its renewability. However, currently there are few evaluation indicators for fuel renewables, and some simple methods are often used to evaluate the renewable properties of fuels, such as using binary numbers 0 and 1 to evaluate whether fuels are renewable, 0 means non-renewable, 1 means renewable regeneration. Such fuel renewable evaluation indicators are too simple and have grea...
