Cerium-based rare-earth catalytic combustion improver and preparation method thereof

Abstract

The invention provides a cerium-based rare-earth catalytic combustion improver. A preparation method of the cerium-based rare-earth catalytic combustion improver comprises the following steps of: forming a carrier by C16H35O4P and/or phosphorous or kerosene; dissolving rear-earth oxide in an H2SO4 or HCI solution to obtain rare-earth feed liquid; mixing the carrier and the feed liquid to obtain a load organic phase; and mixing the load organic phase and cerium-based rare-earth oxide to obtain the cerium-based rare-earth catalytic combustion improver. The invention also discloses the preparation method of the cerium-based rare-earth catalytic combustion improver. The cerium-based rare-earth catalytic combustion improver provided by the invention is low in cost and simple in preparation and operation processes, and the adjustable range of component parameters is wide. After the cerium-based rare-earth catalytic combustion improver is added, the heat value of fuel oil is increased by 10-15%, the content of CO, CH and NOx in discharged exhaust gas is reduced by 50-60%, an energy saving and emission reduction effect can be realized very well, and simultaneously carbon deposits can be effectively cleared away. The cerium-based rare-earth catalytic combustion improver is wide in the application range, has no side effects on equipment and is simple and convenient to add and operate.

Description

technical field [0001] The invention relates to a combustion-supporting agent, in particular to a cerium-based rare-earth catalytic combustion-supporting agent; the invention also relates to a preparation method of the cerium-based rare-earth catalytic combustion-supporting agent. Background technique [0002] With the gradual reduction of global oil resources and the continuous aggravation of global environmental pollution, how to improve fuel combustion efficiency, save energy, and reduce pollution have become two major topics of human concern today. Many experts, scholars, and scientific and technological personnel will be involved in this field As a major scientific research topic, the project is actively explored and researched.

AI Technical Summary

Problems solved by technology

[0003] At present, there are many kinds of catalytic combustion aids on the market, but their effects are not ideal. The disadvantages of common catalytic combustion aids are:

[0004] 1. The use is limited, and most of them are fuels in the form of catalytic combustion-supporting organic gases. For the use of liquid polyalkane petrochemical fuels, many of them fail to achieve the expected results, and even produce side effects such as corrosion and swelling, embrittlement of equipment, etc.

[0005] 2. Common catalytic combustion aids have complex components, cumbersome preparation methods, and are difficult to control; for example, most of them are mixed and synthesized with various alcohols and hydrocarbons under the control of a certain temperature and pressure in different weight ratios, often due to improper control of synthesis parameters, resulting in The product is substandard and does not achieve the expected effect

[0006] 3. Some catalytic combustion aids can only play a combustion-supporting role, but they are not environmentally friendly, and may even increase pollution. Often due to intentional or unintentional doping of heavy metal elements, the pollution of exhaust emissions will increase after addition

[0007] Common catalysts with good effects are relatively expensive, cost-effective, and unsatisfactory economic benefits. Without policy subsidies, ordinary consumers are difficult to accept, so the general public is currently less used
