Problems solved by technology

At present, many power generation and power supply units in China can only rely on mechanical filtration methods to reduce the metal content of degraded waste oil, such as vacuum oil filters and precision oil filters. The methods are labor-intensive, time-consuming, and pollute the environment.
Some units use silica gel, 801 adsorbent, etc., but the effect is poor

Abstract

The invention discloses an absorbent for reducing trace metal content in deteriorated oil, which has been used in an electrical power system, and a production method thereof. The absorbent has the characteristics of non-toxicity, and combustion and explosion resistance, has the advantages of simple production technology, wide raw material sources, low production cost, environment-friendliness, good processing effect on waste oil, and high yield, is capable of saving a large amount of production cost for enterprises, and saves energy for nation.

Description

technical field [0001] The patent of the present invention is an adsorbent for reducing the content of trace metals in degraded oil used in power systems and its production method. Background technique [0002] With the development of the power industry, the demand for power oil continues to increase, and the power oil will inevitably deteriorate under the operating conditions of a certain temperature, atmosphere and electromagnetic field. Regeneration of degraded power oil is an effective saving measure, which can produce significant economic benefits and protect the environment. Using high-efficiency adsorbents to regenerate degraded power oil not only has low fuel consumption and simple process, but also the quality of regenerated oil is close to that of new oil, which saves a large amount of production costs for enterprises, saves precious oil resources for the country, and protects the natural environment. At present, many domestic power generation and power supply uni...
