Накратко на български

Лигнинът от дървесината се използва за едновременно производство на биоразградими полиестери и бутен-2. Това помага за замяната на токсични вещества и суровини от crude oil с алтернативи от биомаса, което подпомага прехода към икономика без изкопаеми горива.

Development of a novel method for a simultaneous production of 2-butene and degradable polyesters from biomass

What is the problem/issue being addressed? The project addresses valorization of largely unvalorized part of wood, namely - lignin. Lignin is considered as a side product of pulp and paper industry and find only low-key application as a heat source. Lignin is a macromolecule which has a great potential to generate bio-based analogs for materials and commodities to substitute their petroleum-based counterparts. In this project we developed a methodology to concomitantly produce a bio-based substitute for bisphenol A (BPA) and butene-2 from lignin. BPA is widely used as a plasticizer and a monomer for production of polyesters and polycarbonates. However, a crude oil origin of BPA and its high toxicity raised multiple concerns and are calling for the development of a substitute. Butene-2 is a valuable light olefin, currently almost entirely produced from crude oil. Bio-based routes to butene-2 are very limited and energy intensive. Overall, the process illustrates a high atom efficacy in conversion of bio-derived molecules into final product via valorization of all carbon atoms. Why is it important for society? Transition to a fossil fuel-free economy is one of the major goals for the global development and is reflected in several European initiatives e.g. European Green Deal. Development of pathways for a direct upgrading of biomass into final products is of paramount importance for this transition. Competition with crude oil-based products is burdened by a well-established structure of the petroleum industry, which has been optimized for many decades. This results in lower production prices for crude oil-based commodities difficult to compete with. Understanding of fundamental aspects of biomass conversion can help to develop novel optimized efficient methods for the biomass upgrading and as such to bring biorefinery closer to life. What are the overall objectives? Overall objectives of the described herein project include: -Set-up specific optimization of reductive catalytic fractionation (RCF) of birch wood to generate iso-eugenol and propenyl syringol enriched lignin depolymerization oil -Optimization of olefin metathesis step of IE and PS to generate targeted bisphenols (substitutes for BPA) and butene-2 -Production of materials (polyesters) based on the obtained BPA-substitute -Application of the developed protocol directly to biomass: from wood to polyesters pathway

Цел на проекта

A high dependence of chemical industry on crude oil raises multiple concerns due to its limited supply and an environmental and politico-economic impact. Thus, the development of more sustainable and renewable systems for the production of fuels and materials is highly desirable. Biomass is an available and renewable source of an organic matter. Production of bio-based fuels and chemicals results in a carbon-neutral cycle. Lignocellulosic biomass or woody biomass is a non-edible source of biomass. It makes lignocellulose an especially attractive source for the production of chemicals, fuels and materials, since it does not directly compete with the production of food. Lignocellulose is in essence a mixture of three classes of polymers: cellulose (38–50 wt%), hemicellulose (23–32 wt%) and lignin (15–40 wt%). Cellulose is a polysaccharide with a regular, semi-crystalline structure; hemicellulose is an amorphous irregular polysaccharide comprising of xylose, galactose, arabinose, mannose, etc. Among these three components lignin stands out as being the largest source of naturally occurring aromatics. Lignin has a complex and inhomogeneous structure. That is why unlike carbohydrate part of biomass (cellulose and hemicellulose), lignin finds a limited application in the chemical industry. In the current project we aim to develop an integrated process for the simultaneous production of degradable aromatic polyesters and 2-butene from lignin. This will be achieved in a three-step process. First, we will implement a reductive catalytic fractionation of wood to generate iso-eugenol and propenyl syringol from lignin . We envision to further transform these products into biphenolic compounds and butene via a metathesis reaction. In the final step we will convert bisphenols into polyesters via a condensation polymerization with maleic and succinic anhydrides.
