文摘
- •
Palygorskite was used as a catalyst support for the transesterification reaction.
- •
The K2CO3-supported palygorskite catalysts exhibited good catalytic performance.
- •
The high biodiesel yield obtained was owing to the high basicity of catalyst.
- •
The main contributions to the basicity of catalyst were K2O and Al–O–K groups.
- •
A little deactivation of catalyst was mainly due to the leaching of K+ ions.
