“…An acetalization strategy was developed for the upgradation of furanic compounds into fuel additives. 118 He et al designed a catalyst-free acetalization method to produce oxygenated fuel additives, 2-(furan-2-yl)-1,3-dioxolane, from renewable furfural and ethylene glycol (Scheme 16c). 119 78.6% yield was obtained in neat cyclohexane at 160 °C after 2 h. It was found that the overused ethylene glycol in this system enables recovery and reutilization without the loss of reaction activity.…”

“…The acetalization/ketalization of glycerol has been studied under different conditions and catalysts. The cyclic acetals and ketal products obtained with aldehydes and ketones, respectively, present a large variety of applications [36]. One of the most desired is solketal, being a renewable raw material, obtained from glycerol by an acid-catalyzed reaction with acetone [12].…”

The valorization of the large amount of crude glycerol formed from the biodiesel industry is of primordial necessity. One possible direction with high interest to the biorefinery sector is the production of fuel additives such as solketal, through the acetalization of glycerol with acetone. This is a chemical process that conciliates high sustainability and economic interest, since solketal contributes to the fulfillment of a Circular Economy Model through its use in biodiesel blends. The key to guarantee high efficiency and high sustainability for solketal production is the use of recovery and recyclable heterogeneous catalysts. Reported works indicate that high yields are attributed to catalyst acidity, mainly the ones containing Brönsted acidic sites. On the other hand, the catalyst stability and its recycling capacity are completely dependent of the support material and the acidic sites incorporation methodology. This review intends to conciliate the information spread on this topic and indicate the most assertive strategies to achieve high solketal production in short reaction time during various reaction cycles.

“…Pyrolysis is an important thermochemical route to convert bulky biomass to biochar and bio-oil of much higher volumetric energy density as well as pyrolytic gases that can be combusted in situ. [1][2][3] Biochar has versatile applications, while bio-oil is commonly accepted as an intermediate product for production of biofuel via further hydrotreatment. [4][5][6] However, owing to the high oxygen content, high acidity and high reactivity of the organics in bio-oil towards polymerization, hydrotreatment of bio-oil for deoxygenation is rather challenging due to rapid coking and deactivation of the catalyst, making the process costly.…”
