Nano rare earth additive, preparation method of nano rare earth additive and application of nano rare earth additive in gas fuel

Abstract

The invention provides a nano rare earth additive for dimethyl ether gas and methanol fuel. In the nano rare earth additive, the compounds or salts of lanthanum, cerium and manganese account for 60% of mass components, the compound or salt of each of lanthanum, cerium and manganese accounts for 10-25%, and the rest components are any three-five compounds or salts of arrowhead, lutetium, erbium, scandium, praseodymium, neodymium and yttrium. The invention also provides a preparation method and application of the nano rare earth additive. Ten nanoscale lanthanide series rare-earth elements are combined to oxygen-containing fuels such as the dimethyl ether gas and the methanol fuel in a reasonable proportion, thus the heat value utilization of the fuel is obviously improved and is superior to that of liquefied petroleum gas, thereby overcoming the defect that the heat value utilization of the oxygen-containing fuels such as the dimethyl ether gas and the methanol fuel is low. The nano rare earth additive can completely replace traditional fuels such as the liquefied petroleum gas, diesel and the like.

Description

technical field [0001] The invention relates to a nano rare earth additive, in particular to a nano lanthanide rare earth element additive mainly composed of lanthanum, cerium and manganese and its application in dimethyl ether gas and methanol fuel. Background technique [0002] Rare earth is known as the "gold" of industry. Because of its excellent physical properties such as light and electromagnetic, it can be combined with other materials to form materials with different properties, which has the unique characteristics of significantly improving product quality and performance. It also has the great effect of greatly improving the performance of military equipment, metallurgy, electronics, laser, nuclear industry, superconductivity and many other high-tech properties.

AI Technical Summary

Problems solved by technology

[0003] Dimethyl ether and methanol are very clean as fuels. As gas and fuels, they are environmentally friendly and energy-saving, but their theoretical calorific value is low, which poses a big problem for users. The power is small and the calorific value is low. Today's oil prices are unstable. In the case of a large amount of imports, dimethyl ether and methanol are facing certain difficulties as alternative fuels

However, in the existing technology, the effect of additives on improving the utilization rate of calorific value is not obvious, and the obtained dimethyl ether and methanol fuels cannot completely replace petroleum liquefied gas
