Abstract

The invention relates to an organic-inorganic compound fertilizer prepared from high-pressure partial oxidation-process coal gasification waste residues and a preparation method of the organic-inorganic compound fertilizer, and belongs to the technical field of fertilizers. The organic-inorganic compound fertilizer comprises the fermented high-pressure partial oxidation-process coal gasification waste residues, fermented chicken manure, fermented straw, urea, potassium sulfate and monoammonium phosphate. The used high-pressure partial oxidation-process coal gasification waste residues have relatively high pH value and porosity and provide air passages for a heap in the fermentation process so as to promote aerobic fermentation; the prepared organic-inorganic compound fertilizer has the effects of regulating the pH value of soil and improving the structure of the soil; in addition, the release speed of fertilizer nutrients can be reduced by virtue of the relatively high porosity thereof, so that the nutrient utilization rate is increased and the times of topdressing are reduced.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer prepared from coal gasification waste residue by a high-pressure partial oxidation method and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] High-pressure partial oxidation coal gasification waste residue usually refers to the use of Texaco furnace to produce synthetic ammonia with coal water slurry as raw material. The remaining ash, coal water slurry and pure oxygen enter the gasifier through the nozzle during the gasification process. Gasification reaction under high pressure to obtain H 2 , CO-based water gas, and then methanol, olefins, etc. can be further synthesized. In order to achieve a high carbon conversion rate during the gasification process, a large amount of heat source is released by partial oxidation reaction, and the temperature in the reactor is maintained at the melting point of coal ash. Above, the ash le...
