Hydrothermal carbonization (HTC) of residues, a patent analysis with patentscope

Abstract

Research related to the environment and energy has been expanding along with a growth in scientific knowledge. In this sense, the use of the hydrothermal carbonization technique (HTC) for the treatment of waste and at the same time generates a value-added fuel product is very promising. The HTC is a treatment with multiple advantages, it is a simple process that operates at low temperatures, the need to treat the raw material is eliminated, energy and storage space are saved, treatment times and the carbon footprint are low and, furthermore, a high calorific value biochar is generated that can be used as fuel among other applications.
