Problems solved by technology

[0003] The current fuel additives have certain limitations in actual use. In the process of production and processing, a large amount of industrial wastewater will be generated during the deoxidation process, and the product yield is uncontrollable, and the production cost increases. In addition, the production safety needs to be further improved; For this reason, we propose a kind of etherification catalyst and preparation method thereof

Embodiment 1

[0026] An etherification catalyst, by percentage, comprising modified silica and activated alumina (a-Aio 3 )42%, copper oxide (CuO), sodium carbonate (N a 2CO 3 ), potassium oxide (K 2 O), titanium dioxide (TIO 2 ), calcium oxide (C a O) and iron powder (Fe) 58%, pore forming agent 1% and molding lubricant 2.5-3%.

[0027] Among them, modified silica is used as aggregate, and activated alumina (a-Aio 3 ), the product is further demolecularly watered, and the depth of etherification is promoted, and the two account for 42% of the total proportion; copper oxide (CuO), sodium carbonate (N a 2CO 3 ), potassium oxide (K 2 O), titanium dioxide (TIO 2 ), calcium oxide (C a O) and iron powder (Fe) increase the carbon chain number (C2-C5) of methanol in the "etherification catalyst", promote the activity of the catalyst, consolidate the dechlorination effect and promote the complexation of protons, denitrification and deoxygenation, accounting for The total ratio is 58%; the...

Embodiment 2

[0037] Aiming at the use effect detection of a kind of etherification catalyst prepared by the method of the present invention, the etherification catalyst prepared by the method of the present invention is selected for use, preferably, by percentage, comprising modified silicon dioxide and activated alumina (a-Aio 3 )42%, copper oxide (CuO), sodium carbonate (N a 2CO 3 ), potassium oxide (K 2 O), titanium dioxide (TIO 2 ), calcium oxide (C a O) and iron powder (Fe) 58%, pore forming agent 1% and molding lubricant 2.75%;

[0038] In addition, 3 groups of commercially available catalysts were selected for use detection comparison, and four control groups A, B, C, and D were randomly set up, wherein A, B, and C were commercially available groups, and group D was the etherification catalyst prepared by the method of the present invention. The test standard is the combustion value, anti-knock performance, emission index and scope of application of each catalyst after being ble...

Abstract

The invention discloses an etherification catalyst and a preparation method thereof, and relates to the technical field of fuel additives. The etherification catalyst comprises the following components by percentage: 42% of modified silica and activated aluminum oxide (a-Aio3), 58% of copper oxide (CuO), sodium carbonate (Na2CO3), potassium oxide (K2O), titanium dioxide (TIO2), calcium oxide (CaO) and iron powder (Fe), 1% of a pore forming agent and 2.5-3% of a forming lubricant; the modified silicon dioxide is used as an aggregate, the activated aluminum oxide (a-Aio3) is added to further remove molecular water from the product and promote the etherification depth, and the activated aluminum oxide and the modified silicon dioxide account for 42% of the total amount; and the copper oxide (CuO), the sodium carbonate (Na2CO3), potassium oxide (K2O) and the titanium dioxide (TIO2) are included. The etherification catalyst disclosed by the invention has good oxidation resistance, anti-knock property and good oil-saving effect, reduces emission of harmful gases in automobile exhaust, is extremely beneficial to environmental protection and energy conservation, and has good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of fuel additives, in particular to an etherification catalyst and a preparation method thereof. Background technique [0002] The traditional solution to engine carbon deposits is to disassemble the engine and clean it, which is not only time-consuming, but more importantly, the advanced supercharging technology and GDI technology make the engine more precise, dismantling and cleaning may bring many follow-up problems, so The fuel system carbon remover (fuel additive) that can be cleaned without disassembly has gradually become a necessary means for us to clean carbon deposits; [0003] The current fuel additives have certain limitations in actual use. In the process of production and processing, a large amount of industrial wastewater will be generated during the deoxidation process, and the product yield is uncontrollable, and the production cost increases. In addition, the production safety needs to be f...
