“…[3,4] Besides environmental concerns as a result of the use of petroleumderived hydrocarbons, the need for a new route to 1,3-BD is further exacerbated due to the possible future shortfall in supply due to the changes of feedstock from naphtha to ethane in the U.S. [5,6] The catalytic conversion of ethanol into 1,3-BD is an attractive alternative, due to the availability of bioethanol which is expected to significantly increase over the next few years from fermentation of sugar rich waste materials (second generation bioethanol). [1,5,7,8] For example in Brazil alone, 23.4 billion litres of bioethanol were produced in 2014. [9] The route most widely accepted to account for 1,3-BD production from ethanol involves five consecutive reactions.…”

Abstract:The conversion of ethanol to 1,3-butadiene (1,3-BD) has been investigated over ZrO2 and ZnO containing magnesia silica oxides prepared by co-precipitation method at different Mg-to-Si molar ratios. The effect of reaction temperature and ethanol flow rate was investigated. The catalyst acidity was modified through the addition of alkali metals (Na, K and Li) to the final materials. Catalysts were characterised by nitrogen physisorption analysis, Xray diffraction, scanning electron microscopy with energy dispersive X-ray, temperature programmed desorption of ammonia, infrared spectroscopy and 29 Si/( 7 Li) NMR spectroscopy. The catalytic results showed that the controlled reduction of catalyst acidity allows suppressing of ethanol dehydration, whilst increasing 1,3-BD selectivity. The best catalytic performance achieved 72 mol % for the combined 1,3-BD and acetaldehyde selectivity.

“…Examples of catalytic conversions mentioned earlier in this section are the conversion of ethanol to ethylene, depolymerization of lignin (in R&D), and methanol production from syngas. The number of catalytic reactions to produce chemicals from biomass and bio-based components is large, see for example [94,108]. One interesting option is the production of furans from cellulose and hemicellulose fractions of biomass.…”

The increasing production of modern bioenergy carriers and biomaterials intensifies the competition for different applications of biomass. To be able to optimize and develop biomass utilization in a sustainable way, this paper first reviews the status and prospects of biomass value chains for heat, power, fuels and materials, next assesses their current and long-term levelized production costs and avoided emissions, and then compares their greenhouse gas abatement costs. At present, the economically and environmentally preferred options are wood chip and pellet combustion in district heating systems and large-scale cofiring power plants (75-81 US$ 2005 /tCO 2 -eq avoided ), and large-scale fermentation of low cost Brazilian sugarcane to ethanol (-65 to -53 $/tCO 2 -eq avoided ) or biomaterials (-60 to -50 $/tCO 2 -eq avoided for ethylene and -320 to -228 $/tCO 2 -eq avoided for PLA; negative costs represent cost effective options). In the longer term, the cultivation and use of lignocellulosic energy crops can play an important role in reducing the costs and improving the emission balance of biomass value chains. Key conversion technologies for lignocellulosic biomass are large-scale gasification (bioenergy and biomaterials) and fermentation (biofuels and biomaterials). However, both routes require improvement of their technological and economic performance. Further improvements can be attained by biorefineries that integrate different conversion technologies to maximize the use of all biomass components.

“…However, achieving sustainability in chemistry is more complex (see [33]). Just switching the carbon source is not sufficient as has been elucidated for bio-plastics [32] and the sustainability assessment of 12 bio-ethanol derived chemicals suggests 1.3 butadiene and diethyl ether as most favorable but the rest as more or less not sustainable [34].…”
