Definitions
- the present invention relates to a process for the production of odorless HTC coal and odorless HTC coal.
- the HTC coal is a product of a hydrothermal carbonization of biomass, z. B. of sewage sludge.
- hydrothermal carbonisation biomass is converted into coal sludge at temperatures between 170 ° C and 250 ° C [degrees Celsius] within a few hours.
- the prior art is described, for example, by DE 10 2007 062 808, DE 10 2007 062 809, DE 10 2007 062 810, DE 10 2007 062 811, DE 10 2007 056 170, DE 10 2008 058 444.
- the hydrothermal carbonization of various types of biomass is explained under different reaction conditions and in various methods.
- Sewage sludge is a waste material from wastewater treatment that must be disposed of by the treatment plants at a charge.
- the high degree of dehydration of up to 70% dry matter content which can be achieved in sewage sludge following treatment by HTC, advantageous because it significantly reduces the amount to be disposed of waste and disposal costs are saved.
- HTC coal is also suitable as a fertilizer and can be applied to fields.
- HTC coal is very odor intensive due to the content of volatile hydrocarbon compounds.
- the subsequent drying of the HTC carbon to improve the shelf life, etc. is known. It is constantly looking for new uses for the re-use of HTC coal.
- an odorless HTC coal to be proposed.
- a process for producing a (substantially odorless) HTC coal, comprising at least the following steps:
- the coal sludge is a HTC coal and an HTC
- Process water includes;
- the steps a) to c) are known from the prior art.
- Next is a drying of the HTC carbon, so a removal of water from the HTC coal, z. B. to improve the shelf life, known.
- temperatures of just over 100 degrees Celsius (at most 110 degrees Celsius) have been regularly used. In particular, it has been avoided that other organic compounds are expelled from the HTC coal by elevated temperatures.
- the HTC coal at higher temperatures for a predeterminable period of time.
- the higher temperatures of more than 150 degrees Celsius, especially at least 175 degrees Celsius, preferably at least 200 degrees Celsius cause that in addition to the water and volatile hydrocarbon compounds from the HTC coal can be largely removed. These volatile hydrocarbon compounds are responsible for the perceptible strong odor of HTC carbon.
- the HTC coal (completely or at least 95 wt .-%, preferably at least 99 wt .-%) to a temperature of more than 150 degrees Celsius, especially more than 180 degrees Celsius, preferably more than 200 degrees Celsius, to be heated.
- HTC coal odorless fertilizer or as Bodenbedecker.
- This fertilizer or this Bodenbedecker could especially in more populated land area, z. B. also be used in urban areas.
- the use of HTC coal as Bodenbedecker, so z. B. as a so-called mulch allows the replacement of previously used materials such as bark mulch, sawdust, green waste, etc. This is achieved by the known mulching baren advantages such as the protection of the soil, or present under the mulch humus layer or the potting soil, the nutrient input by successive composting of HTC coal, and weed control by the reduced incidence of light on the ground on.
- the HTC carbon can be used in predeterminable form, for. As a result of pelleting, and size can be provided, so that the application of the mulch (the Bodenbedeckers or also of the fertilizer) can be improved by people or machines. Furthermore, the HTC carbon can be dyed, so that also with regard to these properties possibly present requirements (eg, aesthetically or in terms of the absorption of heat) can be met.
- the mulching of soils prevents, inter alia, that wind dries out the soil or the water evaporates. Rain, in turn, is taken up by the earth and does not wash away because of the mulch cover.
- the mulch protection layer also acts as a warming blanket and can thus accelerate the growth of the plants.
- the covering of soils with mulch can thus simplify the creation and maintenance of green areas.
- the use of odor-free HTC coal now also makes it possible to use it in inner-city areas.
- the heating in step d) is carried out in particular such that more than 3% by weight, in particular at least 5% by weight, of the dry substance is volatilized.
- the dry matter (the dry residue) is determined in a known manner according to DIN EN 12880. For this purpose, a material is placed on a balance and heated at 105 degrees Celsius until no more weight loss is detected. The now present (dry) material (the dry substance) has no more water.
- the HTC coal it is proposed to treat the HTC coal at elevated temperatures until at least 3% by weight of the dry substance has evaporated. were taken.
- the required heat treatment (temperature and time) can be predetermined on samples.
- the dry weight loss proposed herein is the measurable quantity to determine that the volatile hydrocarbons have been removed from the HTC coal. Experiments have shown that thereafter a (largely) odorless HTC carbon is present.
- step d) at most 18% by weight, preferably at most 12% by weight, preferably at most 7% by weight, of the dry substance are to be volatilized.
- step d) takes place at a temperature of at most 350 degrees Celsius, preferably of at most 300 degrees Celsius, particularly preferably of at most 250 degrees Celsius.
- the step d) is carried out in particular at an ambient pressure (that is to say of approximately 1 bar) and without protective gas (that is to say just no air seal but ambient air).
- the volatile hydrocarbons removed from the HTC coal in step d) can be collected and reused.
- the step b) (ie the hydrothermal carbonization) can be carried out in a known manner at a temperature between 170 to 250 degrees Celsius, with exclusion of air and at a pressure of 5 to 40 megapascals.
- a recoloring of the HTC carbon can be carried out after step d).
- the recoloring takes place in view of the later use of HTC coal.
- the property for absorbing heat energy can thus be influenced.
- Re-coloring causes a change in the color of HTC carbon.
- reshaping of the HTC coal take place.
- the HTC coal can thus be provided in predeterminable shape and size.
- HTC coal wherein the HTC coal at an ambient pressure (ie of about 1 bar) and 20 degrees Celsius (largely or substantially) odorless with respect to volatile carbon compounds ,
- the comments on the method described above apply equally to HTC coal and vice versa.
- the HTC coal due to a color change
- step a a biomass 2 is provided.
- step b a hydrothermal carbonization 3 for producing a coal slurry 4 is performed.
- the coal slurry 4 comprises HTC coal 1 and HTC process water 5.
- step c) HTC coal 1 and HTC process water 5 are separated from each other by mechanical dehydration.
- step d) the HTC coal 1 is heated to a temperature of at least 150 degrees Celsius to remove volatile carbon compounds 6. In this case, more than 3% by weight of the dry matter HTC coal 1 is volatilized.
