Abstract
Bitumen within raw oilsands may be cracked and fully recovered by light hydrocarbon extraction following exposure to modified natural zeolite catalysts under cracking conditions. The recovered bitumen is reduced in viscosity, with lower boiling point distributions. Effective cracking of oilsands bitumen using economical, abundant and readily disposable natural zeolites represents a significant step towards a waterless and environment friendly extraction process.
