Biodiesel production from hempseed oil using alkaline earth metal oxides supporting copper oxide as bi-functional catalysts for transesterification and selective hydrogenation

- Highly unsaturated hempseed oil was converted into high quality biodiesel.
- Cu/SrO is an effective catalyst for transesterification and hydrogenation.
- Increasing hydrogen pressure and reaction temperature favor selective hydrogenation.
- Basic strength and basicity affected catalytic activity for transesterification.
- Surface copper species determined catalytic activity for selective hydrogenation.
