BioGasol is a leading supplier of advanced sugar extraction systems

The Company’s Carbofrac® biomass fractionation technology makes it possible to unlock sugars from plant material, allowing efficient utilisation of Earth’s most abundant renewable resource for fuels, chemicals and materials. The Carbofrac® technology has been specifically developed for biochemical conversions and due to the precise process control high yields and excellent product quality is achieved.

BioGasol also operates the Pentocrobe® fermentation organism, which has the ability to convert all sugars into ethanol simultaneously at high temperatures.

Biomass Sugar Extraction Technology

The Carbofrac continuous biomass sugar extraction reactor is the centrepiece of BioGasol’s technology platform.

In a typical process, the biomass or plant material structure is broken down to enable access to three main components: cellulose (glucose), hemi-cellulose (primarily xylose, arabinose, mannose) and lignin. These components can be converted into energy carriers such as biofuels (e.g. bioethanol, methane), solid fuel pellets, biogas or plastic materials. As sugar is the most important feedstock for biochemical conversion processes (fermentation), this first step (often referred to as pretreatment) is vital for a biochemical process plant, both technically and economically.

The Carbofrac® system is designed to utilise an elevated temperature under a pressure corresponding to steam temperature. When the pretreated material is released, a rapid pressure drop, or “steam explosion”, occurs which further breaks down the structure of the biomass. Additives such as acid, base or solvents act as catalysts in the process and are typically applied in order to facilitate depolymerisation of the sugar-chains in the biomass. Dilute acid catalysed steam-explosion pretreatment is BioGasol’s reference process.
