Warm Cloud Catalyst, Preparation Method Therefor and Application Thereof

A method for preparing a warm cloud catalyst, wherein when the surfactant is in form of a solution, the method comprising:

• 1) preparing the surfactant solution, wherein in the surfactant solution, the mass concentration of a solute is 0.5%-35%;
• 2) evenly mixing 15-32 parts by weight of the prepared surfactant solution with 80-120 parts by weight of the plant ash/plant powder/plant carbon powder to obtain a mixture;
• and
• 3) drying the mixture, then adding 2-10 parts of the thickening agent and evenly mixing, and then sieving to obtain a warm cloud catalyst,
• wherein the warm cloud catalyst comprises the following components in parts by weight:
• 80-120 parts of a plant ash/plant powder/plant carbon powder,
• 15-32 parts of a surfactant solution, and
• 2-10 parts of a thickening agent.

A method comprising:

• using a warm cloud catalyst in warm cloud precipitation, reservoir and pond water addition, precipitation redistribution, flood prevention and control or drought disasters, wherein the warm cloud catalyst comprises the following components in parts by weight:
• 80-120 parts of a plant ash/plant powder/plant carbon powder,
• 0.5-5 parts of a surfactant dry powder or 15-32 parts of a surfactant solution, and
• 2-10 parts of a thickening agent.

A method for preparing a warm cloud catalyst, wherein when the surfactant is in form of a dry powder, the method comprising:

• a) grinding 2-20 parts of the dry plant ash/plant powder/plant carbon powder, together with 0.5-5 parts of the surfactant dry powder and 2-10 parts of the thickening agent dry powder, and sieving through a 200-mesh sieve, to obtain a surfactant and thickening agent dry powder with a smaller particle size;
• b) further fully mixing the rest plant ash/plant powder/plant carbon powder with the finer dry powder prepared in a), so as to disperse the surfactant and the thickening agent and reduce contents of the surfactant and of the thickening agent;
• and
• c) sieving the mixture prepared in b) to obtain the warm cloud catalyst, wherein the warm cloud catalyst comprises the following components in parts by weight:
• 80-120 parts of a plant ash/plant powder/plant carbon powder,
• 0.5-5 parts of a surfactant dry powder, and
• 2-10 parts of a thickening agent.
