“…Dioxane is another rather commonly used polar organic solvent (Table 2.4). 91,[104][105][106][107][108][109] Dioxane has an effect on the glucose-fructose isomerization, mediated by a Sn-β metal catalyst, with progressively more aqueous dioxane-water solvent systems being less and less effective in the sugar conversion. 105 Specifically, the fructose conversion after 2 h of reaction drops from >90 mol% to approx.…”

“…75-80 mol% selectivity in the presence of a solid carbon-based acid catalyst, derived from calcium gluconate. 107 Like DMSO, dioxane has also been employed in the treatment of more recalcitrant starting materials (e.g., corncob and bamboo lignocellulosic biomass), with very promising outcomes. 108,109 Specifically, a fully organic dioxane environment gave rise to >90 mol% yield of furfural starting from bamboo biomass, in an HCl-catalyzed process.…”

“…Several other polar organic solvents have been used in the production of furans from sugars, e.g., acetone, butanone, GBL, and acetonitrile (Table 2.5). 82,86,99,104,107,[110][111][112][113][114][115] Acetone in combination with a choline chloride-ethylene glycol deep eutectic solvent (2:5 v-v DES-acetone mixture) gave furfural starting from xylose with approx. 70 mol% selectivity, using H2SO4 as a catalyst.…”

“…When the water content of the system is limited or even absent, the characterization of the behavior of the acid catalyst is more complex. [84][85][86]88,[90][91][92][93][94]98,102,[106][107][108][109] The acid- catalyzed process of sugar dehydration involves a proton transfer from the catalyst onto the sugar, which affects the β-elimination of the hydroxyl groups. 1,22,[33][34][35][36][37][38][39][40] In mainly aqueous media, such proton transfer is mediated by water molecules, but with the decrease of the water content the catalyst activity increases.…”

Furfural manufacture from xylose : routes towards high selectivity and novel processes

Planet Earth is facing a human-induced climate crisis. 1 Scientists from numerous nations have raised concern about this issue at various instances in the past, with one of the latest public warning having arrived in January 2020. 1 The alarming trends observed in the parameters that we use to describe climate and environment (e.g., desertification, availability of fresh water, air pollution) show that drastic, politically driven changes are urgently necessary. 1 With greenhouse gas (GHG) emissions still rapidly rising, and most public discussions focused on global surface temperature only, it is of fundamental importance to understand that this environmental crisis is related to social and economic factors embedded in our society. 1,2 In parallel, and strongly related, to the climate crisis, our society is facing an energy crisis, which is directly connected to the steep rise in energy demand. 3,4 These two crises are intertwined, since the combustion of crude oil, natural gas and coal still is the primary energy sources worldwide, both for transportation of people and goods, fueling industry and infrastructures, and for ensuring the stability of the energy grid. 4 The product of combustion of these fossil fuels is CO2, which is an important contributor to the greenhouse effect. The increased energy demand is due to worldwide industrial development, coupled with an average increase of wealth. [3][4][5] This scenario, in combination with the increasing costs of extraction and manufacture of fossil fuels, is becoming a troubling bottleneck for economic development. [3][4][5] Currently, the addition of green and/or renewable sources of energy (e.g., hydroelectric, solar, wind and nuclear energy) is rapidly growing. 5 Yet, we must realize that just compensating the growing energy demand with these 'clean' energy sources is not sufficient. Reducing the (absolute) contributions of fossil fuels to the energy palette is absolutely necessary to act on the climate crisis and reduce, for example the CO2 levels in the atmosphere. 5 Making humanity fully independent from fossil fuels is an incredibly complex task. 1,2 To do so, the chain of production and consumption of energy, at all levels, needs to be redesigned with drastic, both politically and economically driven international choices. 1,2 Next to these necessary societal changes, research is needed to explore possible alternatives for fossil fuels, which would ease this transition with the aim to avoid, or minimize, an economic crisis. [1][2][3][4][5] Particularly, some sectors of industry and transportation, e.g., heavy industry and aviation, are extremely challenging to decarbonize and cannot solely rely on solar and wind energy, requiring the development of renewable fuels and chemicals. 6 Reducing, and finally eliminating, fossil resources such as oil is exceptionally complex, as these resources are also the basis for the current petrochemical industry. 6,7 The petrochemical industry, one of the largest during the last century, continues to grow t...

More Sustainable Chemical Activation Strategies for the Production of Porous Carbons

2020

View full text Add to dashboard Cite

The preparation of porous carbons attracts a great deal of attention given the importance of these materials in many emerging applications, such as hydrogen storage, CO2 capture, and energy storage in supercapacitors and batteries. In particular, porous carbons produced by applying chemical activation methods are preferred because of the high pore development achieved. However, given the environmental risks associated with conventional activating agents such as KOH, the development of greener chemical activation methodologies is an important objective. This Review summarizes recent progress in the production of porous carbons by using more sustainable strategies based on chemical activation. The use of less‐corrosive chemical agents as an alternative to KOH is thoroughly reviewed. In addition, progress achieved to date by using emerging self‐activation methodologies applied to organic salts and biomass products is also discussed.

Solid Acid Catalyst Derived from Cotton for Conversion of Xylose and Corn Cob to Furfural

et al. 2022

Carbon‐based solid acid catalysts (CS−SO3H) were prepared by one‐pot carbonization‐sulfonation method with concentrated sulfuric acid using cotton as raw material, which was used to transformation of xylose and corn cob to furfural. The catalyst preparation conditions were optimized to be that the cotton mass/sulfuric acid volume ratio is 1 : 20 (g/mL), and the reaction is carried out at 160 °C for 10 h. The morphology, functional groups and surface chemical state were investigated. The yield of furfural can reach 87.3 % from xylose under the optimal reaction condition of 0.1 g xylose, 0.05 g catalyst, 180 °C for 90 min in 5.0 mL γ‐valerolactone‐water solvent. The yield of furfural can reach 63.2 % by the direct one‐pot conversion of corn cob over the CS−SO3H under the optimal reaction condition of 0.1 g corn cob, 0.1 g catalyst, 190 °C for 90 min in 5.0 mL γ‐valerolactone‐water solvent. The catalytic activity gradually declined when it was cycled for four times. The reason was determined to be the partial shedding of the sulfonic acid groups grafted on the catalyst during the reaction and insoluble humus accumulated on the catalyst surface. After regeneration, the catalytic activity can be restored.
