A Polystyrene supported Scandium (III) microencapsulated Lewis acid catalyst for hydrothermal carbonization of glucose

Original language description

Hydrothermal carbonization of glucose in the absence and presence of recoverablesolid polystyrene-supported microencapsulated Lewis acid catalyst has been carriedout at 180 and 200 ºC for 6, 12, and 24 h using either 0.25 g or 0.5 g of catalyst. Theeffects of temperature, residence time, and catalyst loading on the resulting hydrocharswere investigated. At the lowest temperature (180 ºC) and the shortest residence time(6 h) without the presence of catalyst, the glucose conversion was the lowest asexpected. No hydrochar was formed at 180 ºC for 6 h without using any catalyst. Incatalytic runs, the formation of hydrochar was observed under identical conditionsalthough the yields of hydrochar were low. The use of the catalyst increased the yieldof acid compounds (acetic, glycolic, lactic and levulinic) at the expense of 5-hydroxymethylfurfural under identical conditions. Except for 180 ºC for 6 and 12 h, theuse of catalyst decreased the yield of hydrochars. The use of the catalyst led toincreasing the diameter of carbon sphere particles under identical conditions. Thepresence of the catalyst resulted in the production of a notable amount, approximately20% by weight, of levulinic acid as a by-product.
