Definitions
- the invention relates to a method for producing an organic fertilizer with humic character according to the preamble of claim 1.
- the invention further relates to a fertilizer produced by the method with a special material composition and its use.
- the fertilizer can be used as a natural means for sustainable plant nutrition and soil improvement.
- lignite Because of their chemical properties and their availability, lignite has long been of interest as a starting material for the production of substances or mixtures of substances with a fertilizing effect.
- a method according to the preamble of claim 1 is known from DE 22 47 938 A.
- Raw lignite is treated in an aqueous suspension at elevated temperature (80 ° to 200 ° C) and pressure (up to 50 atm) with oxidizing and ammonizing.
- the suspension contains 95 to 70 percent by weight of water, ammonia is added, the mixture is heated to the reaction temperature in a pressure vessel and then brought to the reaction pressure by injecting pure oxygen.
- a specific way of setting a specific pH is not described.
- EP 0 298 710 discloses a process in which coal is processed with an aqueous medium to form a slurry with a pH in the range from 4 to 9.
- the slurry is oxidized with a gaseous oxidizing agent, such as oxygen, air, and mixtures thereof.
- the oxidation takes place at temperatures of 100 to 300 ° C, at a pressure of 0.1 to 10 MPa and a reaction time of 5 to 600 minutes.
- the product thus oxidized only has a nitrogen content of less than 2%.
- the result is an unfavorable C / N ratio of approx. 35 to 40.
- a method for growth stimulation of seedlings which consists in that a carbon oxidation product is supplied to the medium in which the seedling grows.
- a product is proposed as the carbon oxidation product, which by dry oxidation of the coal with oxygen, in particular air, at a temperature between 120 and 350 ° C. and a partial pressure of oxygen between 0.01 and 1 MPa, preferably between 0.01 and 0.5 MPa, during a contact time between 15 and 600 minutes is produced.
- a product which is produced in accordance with EP 0 298 710 is proposed as a further carbon oxidation product.
- the carbon oxidation product produced by dry oxidation typically has a nitrogen content of less than 2% and a C / N ratio of approx. 35.
- lignite is mixed with inorganic material and / or organic waste. These mixtures are optionally subjected to mechanical processing and / or hydrolysis processes beforehand.
- coal lumic acids have been extracted, for example, according to US Pat. No. 3,770,411 with aqueous ammonia and the extracts have been reacted with phosphoric acid.
- the object of the invention is to convert an organic raw material which is available in large quantities in nature by a process into an organic fertilizer with a pronounced humic character, with an increased nitrogen content with a favorable C / N ratio and long-term ineffectiveness
- the lignite is suspended in an aqueous ammonia medium with a pH greater than 9 to 12 and is partially dissolved and oxidized at a temperature of 20 to 100 ° C. under normal pressure, and the organic fertilizer as Dispersion in an aqueous medium is obtained by thickening or drying, a C / N ratio of 9 to 15 being obtained
- the special feature of the process is that the lignite is gently oxidized in a mixture of an aqueous suspension and solution under alkaline conditions in the presence of an N-basic reactant, such as in particular ammonia
- lignite is first converted into an aqueous-ammoniacal mixture of suspension and solution and is now alkalinized in the reactor, which is constructed according to the injector principle, initially without the addition of oxygen / air and in the process over a controllable time of up to 0 Brought to the oxidation temperature for 5 hours
- the oxidation gas is now fed into the reaction mixture via the injector. According to this procedure, a system of liquid and fine-bubble foam is formed a large exchange area between the organic material in the liquid and the oxidizing gas.
- the effective oxidation can be achieved both by oxygen and by air and here with an oxygen partial pressure which is significantly lower than that of pure MP, compared to the use of pure oxygen.
- the oxygen entry is closed and the reaction is stopped.
- the reaction mixture is now cooled to a temperature which is necessary for working up without further oxygen supply.
- the special reactor advantageously allows cooling times of ⁇ 1 hour.
- the oxidation can be carried out with air or oxygen, or air / oxygen mixtures and in an aqueous-ammoniacal environment with an ammonia concentration of up to 7%.
- Lignite can be used with different particle sizes.
- the oxidation is advantageously carried out at a reaction temperature of up to 100 ° C. over a period of 0.5 to 4 hours.
- lignite in a mixture with technical lignins of the pulp industry, as well as wood hydrolysis lignite in a mixture with lignin and lignocellulosic material from the steam explosion digestion for fiber production and lignite in a mixture with lignocellulosic material, such as wood or bark particles, are used as the starting material used.
- a further advantageous embodiment of the method provides that during or after the oxidation of the lignite or the lignite in a mixture with lignins, further doping with macro- and micronutrients, such as with phosphorus, takes place.
- An organic fertilizer produced by the method is indicated by the features mentioned in claim 8.
- the fertilizer according to the invention is characterized by a particularly favorable C / N ratio of 9 to 15, the nitrogen being present in differently bound form at this C / N ratio.
- the lignite although containing a high proportion Structures of coal-specific humic or fulvic acid type are present, which are highly condensed, as a suspension or partially dissolved by oxidation in an aqueous-ammoniacal environment, to form a humus-like fertilizer with a long-term non-effect.
- the process according to the invention introduces nitrogen into the coal-specific humic substances in a chemical bond and the chemical structure of these coal luminescent substances is modified so that they are more closely similar to the humic substances of the soil formed under natural conditions.At the same time, the high-molecular organic structures of the coal, which are not similar to humic substance, are partially broken down, i.e. split up into smaller molecular sizes and functionalized with polar groups
- the process can be implemented in such a way that a water-ammoniacal mixture of suspension and solution of the starting material is circulated through a heat exchanger and the oxidation gas is introduced via an injector system
- Oxygen or only air is used as the oxidizing agent.
- it is advantageously carried out according to the invention under mild conditions at normal pressure and temperatures up to 100.degree
- the products made from lignite using the process can contain up to 6% total nitrogen, which is available in various chemical bond forms.
- the chemical bond forms differ in terms of their hydrolyzability.
- the nitrogen bound in the ammonium form (20 - 45% of the total nitrogen) is also in water Suspended MgO can easily be split off as ammonia, while the organic bond forms (55 - 80% of the total nitrogen) are more difficult to hydrolyze.
- Part of the organically bound nitrogen is in the amide form (up to 20% of the total nitrogen), which is normally done with dilute sodium hydroxide solution can be hydrolyzed under the conditions of steam distillation. The one which cannot be hydrolyzed under these experimental conditions The proportion is called solid organically bound nitrogen (up to 60% of the
- the atomic ratio H / C increases from 1.05 to 1.28, while in the coal-humic acids
- brown coal can be from different locations
- Bark particles can be used
- the mixture is then pumped through a tubular reactor and a heat exchanger and brought to the reaction temperature of 70-76 ° C. After the specified reaction temperature has been reached, an amount of 30-50 hours is metered in via an injection system and the oxidative ammonolysis is started constant pumping and constant supply of the oxidation gas over a reaction time of 1 to 4 hours. At the end of the reaction, the oxygen supply is closed, the reaction mixture is cooled with pumping and subsequently discharged. The reaction product is finally obtained as a solid by evaporation or vacuum evaporation
- the reaction is carried out as in embodiment 1, variant 1 or 2, but instead of oxygen, air is metered in as the oxidizing gas in the amount of 50 l / h.
- the nitrogen yield was determined analytically Elemental analysis:
- the mixture was then pumped through a tubular reactor and a heat exchanger and brought to the reaction temperature of 70-76 ° C.
