Catalytic Transformation of Biomass Derivatives to Value‐Added Chemicals and Fuels in Continuous Flow Microreactors

“…Thermochemical transformations of biomass in microreactors have been occasionally reported and are not included in this review, for which the readers are referred to the corresponding literatures: pyrolysis (coupled with analytical equipment), [318][319][320] and the production of syngas by the (catalytic aqueous phase) reforming of carbohydrates [321][322][323] or glycerol. [324][325][326][327] Also the Fischer-Tropsch synthesis of liquid olefins from biomass derived syngas or methane has been reported in microreactors, [328][329][330][331] but will not be elaborated in this review.…”

Hydrogen from Renewables: A Case Study of Glycerol Reforming

“…From this standpoint, APR and SR are two reasonable valorisation processes. Glycerol reforming is an endothermic reaction and can be summarized as follows [25]: C 3 H 8 O 3 + xH 2 O + yO 2 → aH 2 + bCO 2 + cCO + dH 2 O + eCH 4 (1)…”

“…From this standpoint, APR and SR are two reasonable valorisation processes. Glycerol reforming is an endothermic reaction and can be summarized as follows [25]: C3H8O3 + xH2O + yO2 → aH2 + bCO2 + cCO + dH2O + eCH4 (1) SR occurs at high temperatures (e.g., 800 °C) and, generally, low pressure, and is a vapor phase catalytic process where y = 0 and x > 0. The main drawbacks of the investigated reaction pathway are catalyst deactivation and high energy consumption.…”

Acetalization Catalysts for Synthesis of Valuable Oxygenated Fuel Additives from Glycerol

“…A large number of value-added chemicals such as propanediols [39], acrolein [40], dihydroxyacetone [41], glyceric acid [42], hydrogen [43], synthesis gas [44], esters [45,46], etc., can be produced from glycerol using oxidation, reduction and other catalytic reactions (Scheme 1). Oxidation of primary, secondary, and all three groups yields different molecules of C 3 acids, aldehydes, and ketones [47,48].…”
