Description

Method for manufacturing eco-friendly bio-solid fuel using livestock manure {A method for manufacturing eco-friendly bio-solid fuel using livestock manure}

The present invention relates to a method for producing eco-friendly biosolid fuel using livestock manure, and in particular, when producing biosolid fuel through hydrothermal carbonization of livestock waste (livestock manure), a catalyst is added to produce solid fuel. It relates to a method for producing eco-friendly bio solid fuel using hydrothermal carbonization of livestock manure and catalyst technology, which can increase calorific value and reduce harmful components.

The information described below merely provides background information related to the present invention and does not constitute prior art.

In general, the main method of converting livestock manure into energy is to manufacture it as a solid fuel.

Methods for producing solid fuel include a carbonization (torrefection), a torrefaction process, a drying process, a hydrothermal carbonization process, and the like.

Torrefection and torrefaction processes have disadvantages in that moisture of the reactants must be removed and an oxygen-free atmosphere must be created by injecting an inert gas (argon, nitrogen, helium, etc.) into the reactor.

In addition, the drying process is the simplest method that can be performed with only a heat source and is the most common method for producing solid fuel.

Since livestock manure has an average moisture content of about 60 to 80% by weight, the process of drying livestock manure is not economical considering the input heat energy.

In addition, harmful gases generated during drying may cause environmental pollution.

However, since the hydrothermal carbonization process is a wet process that does not require drying, a primary drying process is unnecessary, and it is a technology capable of reducing harmful components while showing a higher calorific value than solid fuel produced from an existing drying process.

Generally, the high calorific value of dried cattle and pig manure is 3,500~4,500 kcal/kg, which is suitable for the calorific value standard of bio solid fuel (low calorific value 3,000 kcal/kg) set by the Ministry of Environment, but the high calorific value of dried chicken manure is 2,000~2,500 kcal/kg kg does not meet the standard.

Therefore, when producing bio-solid fuel from chicken manure, there is a hassle of mixing other raw materials with high calorific value.
