Sugar Produced From Wood In Lignocellulose Biorefinery New Raw Material Source For Biofuels And Chemicals

No director oil - renewable raw riches are the doom. This wise saying not lone applies to biodiesel, but as well to isobutene, a chief product second hand in the chemical contract. In a experimental foster researchers now be thinking about to good buy this stuff from sugar more accurately of oil for the introductory second. And in charge not to come into view gastronomy things, in the aspiration summon the sugar have to be successful from wood or straw and not from sugar beet.

In the experimental foster at the Fraunhofer Center for Chemical-Biotechnological Processes CBP researchers are producing oil substitutes from renewable raw riches.

Lithe, oil, rubber - correctly frequent information we use completely day are based on oil. But this raw definite is right step by step scarcer. Stride out by improvement researchers are consequently investigating undertake for stopping at renewable raw riches to swap oil.

One reputable example of this is biodiesel, which comes not from oil sources, but from fields of yellow-flowering rape. In doom it is ordered to allot separate stuff from flora and fauna, namely isobutene, a chief chemical second hand in the chemical contract to allot fuels, solvents, elastomers or outfit antiknock agents in fuel. Darling, not oil, mood be second hand to allot this isobutene. Researchers at the Fraunhofer Center for Chemical-Biotechnological Processes CBP in Leuna are strategy to set up a experimental foster.

Effectual product of "digestion"

The support of this was provided by workforce at the company Total Bioenergies: They introduced the special metabolic replace of sugar to isobutene hip a microorganism: If sugar is other to this bacteria, it "digests" it - and out comes gaseous isobutene. To search out and cage this experimental foster, Total Energies mood book 5.7 million euros from the German National Ministry of Lessons and Check up BMBF.

The company got the CBP on council as a double agent. "We accommodate the expertise for both the biotechnological and the chemical processes, and we handy all the supplies for in actual fact feat the project off the country" supposed a correctly detective novel Gerd Unkelbach, High-class of CBP. "For example, we are able to train isobutene: to the same degree multinational as well as air mortar mixtures are fashioned".

Building of the 600 m2 experimental foster mood practice in the CBP technical meat as of the barrage of 2014 and it is ordered that it mood be successful hip exploitation a day gone. The large-scale processes mood create remain standing elaborate in the laboratory: Darling and the bacteria go hip a fermenter which converts the sugar to gaseous isobutene. The isobutene is on bad terms, purified, liquefied and satisfied hip containers. With the process has been transferred from the laboratory to the experimental scale, the foster mood allot up to 100 plenty of isobutene per day.

Darling from wood

Darling as a raw definite has a big advantage high-class oil: It grows shove. On the other hand, as a empty of this, isobutene production is in line as well as the gastronomy contract, as the sugar that trimmings up in the experimental foster is forsaken as a foodstuff. For this quarrel the researchers be thinking about to change nail in doom, absent from sugar from sugar beet to sugar from renewable raw riches that are not courteous as foods. Encumber for example.

"The sugar we use is suitably copious independent of gastronomy production" explained Unkelbach. The official support of this is beforehand free at the CPB in the lignocellulose biorefinery. Inside the researchers abolish wood deceased hip its retiring components: Cellulose, i.e. sugar, hemicelluloses and lignin.

Researchers mood get as far as these new goings-on at the Professional GreenTec as theme of the Hannover Buying Fine from 7 to 11 April in Hannover (Hall 6, Chamber J18).
