“…Finally, to the best of our knowledge, there are no publications studying the transfer hydrogenation of furfural with glycerol as a hydrogen donor, despite publications indicating its transfer hydrogenation capacity and the generation of dihydroxyacetone (DHA) and/or lactic acid coproducts. − Hence, due to its potential low cost as a byproduct from biodiesel production, further research should also consider glycerol as a hydrogen donor, with focus on coproducing DHA, a high-value (US$25,000/tonne) compound mainly used for self-tanning products . As discussed previously, a significant advantage of CTH is the possibility of selling the dehydrogenated hydrogen donor coproduct, generating additional revenue.…”

Catalytic transfer hydrogenation (CTH) has gained attention as a potentially more sustainable process than conventional hydrogenation with H2 gas. In this process, hydrogen is supplied in situ from a donor molecule without the need for high-pressure H2. We developed a conceptual commercial process for the transfer hydrogenation of furfural into furfuryl alcohol (FFA) and performed techno-economic and greenhouse gas (GHG) analyses aiming to identify bottlenecks and guide future research in this field. Two hydrogen donor compounds were considered: 2-propanol and ethanol. Total capital investment varies between US$24.9 and 33.4 million for these processes, and the minimum selling price for FFA is below the market price of US$1.52/kg only with ethanol as a hydrogen donor. The main impact on the profitability is from selling the dehydrogenated hydrogen donor as a coproduct. Thus, low-cost hydrogen donors that generate high-value dehydrogenation products are required for this process to be competitive with conventional hydrogenation. In addition, utilizing a hydrogen donor that comes free of embodied impact and/or that avoids a GHG release is required for CTH to have a lower GHG emission intensity than conventional hydrogenation.

A combination of different physio‐chemical treatment steps was applied to purify industrially derived crude glycerol at laboratory scale. The full process included acid–base treatments, phase separation, and adsorption, and the glycerol purity and recovery were optimized by varying the pH during saponification and acidification, the solvent‐to‐glycerol ratio, and type of base used in the process to enhance both. The testing campaign resulted in a final purity of up to 87% wt starting from a very low‐quality ‘end‐of‐life’ waste glycerol sampled from different refineries. The net glycerol recovery at laboratory scale reached 42% of the initial glycerol in the feedstock and the maximum ash removal exceeded 90% given the low quality of the feedstock and high content of impurities and the attempt to achieve high glycerol recovery. The experiment showed that mild operations such as saponification with KOH (pH of 8), acidification with H3PO4 (pH of 6), an ideal 2‐propanol to glycerol volume ratio equal to 3 and potassium hydroxide as a base for the neutralisation step were the optimum conditions despite the differences between samples. The sequence of the processes proposed was therefore considered a viable option to treat any kind of crude glycerol to make it profitable for fuel and chemical applications.
