Hydrothermal carbonization (HTC) is a low-temperature thermochemical conversion process to upgrade side streams into hydrochar with interesting properties. Possible areas of use are e.g. soil improvement, environmental remediation, energy storage, and as an energy source.
RISE subsidiary RISE Processum in Örnsköldsvik has several reactors for scaling up HTC. On a smaller scale, there are 200 and 400 ml autoclave reactors from Büchi Glass. These can be used at temperatures up to 285 °C and pressures up to 70 bar. If larger volumes are needed, it may be appropriate to choose a 50 L batch reactor that can be run at temperatures up to 230 °C and pressures up to 20 bar.
In the coming years, the plan is to supplement the test bed with two new batch reactors, 50L and 250L, both of which can handle temperatures up to 300 °C and 40-60 bar.
