Abstract
Development of stable, reusable,
and water-tolerant solid acid
catalysts in the conversion of polysaccharides to give value-added
chemicals is vital because catalysts are prone to undergo morphological
changes during the reactions. With the anticipation that silicoaluminophosphate
(SAPO) catalysts will have higher hydrothermal stability, those were
synthesized, characterized, and employed in a one-pot conversion of
hemicellulose. SAPO-44 catalyst at 170 °C within 8 h could give
63% furfural yield with 88% mass balance and showed similar activity
up to at least 8 catalytic cycles. The morphological studies revealed
that SAPO catalysts having hydrophilic characteristics are stable
under reaction conditions
