New plant coverts biomass to bio-oil

On 22 May 2015, Aarhus University is inaugurating an HTL commander plant during AU Foulum. The new plant translates organic materials such as weed or organic rubbish into bio-crude oil, that can reinstate hoary oil for producing fuels and chemicals. The plant is shaped on newly developed, ground-breaking technologies.

The oil that is now pumped adult from a subsurface was shaped between 10 and 160 million years ago. This took place with a deposition of organic element on a sea floor. As a element was gradually lonesome by new deposits, a vigour and feverishness increasing – and it was converted to wanton oil.

This can be replicated by hydrothermal liquefaction (HTL) technology, a routine in that organic element is churned with H2O and unprotected to high vigour and temperature. The outcome is a gelatinous oil that can be polished to diesel oil and a substantial series of other products.

The routine has been famous given a 1930s, though has never unequivocally taken off on a vast scale, quite since a routine is connected with poignant technological challenges. Some of these vital hurdles will presumably be solved with a new Foulum plant.

“The new plant is shaped on a upsurge reactor, with a solid influx of biomass and an outflow of bio-oil from a other end. The routine takes place in a 120-metre-long pipe, where a flowing biomass is exhilarated to 450 degrees and subjected to a vigour of adult to 350 bar,” says Associate Professor Ib Johannsen, Department of Engineering, who is obliged for conceptualizing a plant.

The new plant will capacitate a continual routine in that vigour is confirmed and feverishness detriment is reduced by means of feverishness recovery. This means that a plant is approaching to be distant some-more energy-efficient than prior facilities.

“One of a parameters in a pattern of a commander plan is a recycling of a poignant volume of a feverishness used to feverishness a biomass. Our aim is that a upgraded plant will be means to recycle as most as 85 per cent of a heat,” explains Associate Professor Johannsen.

The new plant is a commander project, though a aspiration is that a pattern can be scaled for blurb use.

If a record proves to be amply efficient, it could also minister to elucidate a series of meridian and environmental problems. The record could initial and inaugural reinstate hoary fuels with bio-oil shaped on residual biomass.

Facilities will be set adult beside a HTL plant for extracting proteins from immature biomass, thereby formulating a total height for biorefining on a commander scale. This height will be means to play alongside determined activities during AU Foulum in fields such as biogas and collect technology, as good as endless experiments with softened apparatus potency in biomass production.

The altogether height will emanate new cultivation and prolongation opportunities in agriculture. One of a options being investigated during benefaction is replacing alien soy protein with weed protein grown in Denmark.
