Methanol gasoline water soluble agent

The invention relates to a methanol gasoline water soluble agent, belonging to the field of alcohol gasoline alternative fuel additives, and being prepared from the following raw materials by weight percent: 54.7 percent to 62.5 percent of partially saponified ammonium soap and 37.5 percent to 45.3 percent of fatty alcohol, wherein the partially saponified ammonium soap is an incomplete saponified product fatty acid ammonium generated by partial saponification reaction of animal and vegetable oils, waste oil or organic acid and organic ammonium or inorganic ammonium. Compared with a traditional cosolvent, the methanol gasoline water soluble agent has the advantages of simple preparation, little agent addition, low cost, favorable effect and the like. By using the water soluble agent in methanol gasoline of each grade of M15 to M100, the methanol gasoline can generally keep non-stratification by being dissolved in water for 3 percent to 5 percent. Finished methanol gasoline can be dissolved in water for 6 percent to 7 percent without stratification to the upper limit, is not turbid, is clear and transparent, has long stationary phase, and can completely satisfy the production, storage, transportation and use requirements of the methanol gasoline so as to solve the problem that the methanol gasoline generates phase separation because of the existence of water for a long time, and create beneficial conditions for generalization and popularization of the methanol gasoline.

Enhanced denitration monolithic catalyst coating slurry, and preparation method and application thereof

The invention discloses an enhanced denitration monolithic catalyst coating slurry having a long stable period, and a preparation method thereof. The slurry is prepared through adding proper amounts of an inorganic binder, a pH regulator, a hyperdispersant and a foam inhibitor to a V2O5-WO3-TiO2 catalyst system and carrying out ball milling. The polymer type hyperdispersant having an anchoring group and a solvation chain is used in the ball milling process of the catalyst slurry to substitute a traditional homopolymer, so the stable period of the slurry is greatly prolonged, stable storage, conveyage and use of the slurry are benefited, and the preparation method is especially suitable for industrial production amplification. Additionally, the addition amount of the hyperdispersant is small, so the hyperdispersant almost has no obvious influences on the subsequent preparation process of the monolithic catalyst, such as channel blowing, drying and calcination.
