Rapid heating technique gives high yields of bio-oils from kelp

A Norwegian research group have reported that they have achieved bio-oil yields of 79% from sugar kelp (Laminaria saccharina) – an improvement on the yields closer to 20% obtained by other researchers working with the same species.

They used a technique called fast hydrothermal liquefaction to rapidy heat the kelp and bring it to the optimum temperature to produce bio-oil.

“What we are trying to do is to mimic natural processes to produce oil,” said Khanh-Quang Tran, an associate professor in NTNU’s Department of Energy and Process Engineering. “However, while petroleum oil is produced naturally on a geologic time scale, we can do it in minutes.
