While microalgae oil was perceived as the preferred feedstock to supply the inelastic global demand for biofuel, industry and academia attempts to create viable microalgae-oil production processes has not reach the desired goal yet. UniVerve Ltd. has developed an innovative technological process that provides a scalable, cost effective and sustainable solution for the production of microalgae-biomass. The oil, which can be extracted with off-the-shelf wet-extraction technologies and used as an excellent feedstock for all kinds of biofuel, is expected to be produced at up to US$50 per barrel. As the biomass also contains omega-3, proteins and other valuable biomaterials that can be commercialized in the food and feed markets, a microalgae farm can serve the biofuel, food and feed industries, which currently face an increasing lack of quality feedstock at an affordable price.
The pyrolysis characteristics of Chlorella vulgaris (C. Vulgaris) (one kind of microalgae) by microwave oven are studied. The microwave pyrolysis of C. Vulgaris is carried out under different dosages of C. Vulgaris and different contents of activated carbon. The products and pyrolysis temperature are analyzed in order to obtain the optimal conditions. The results indicate that with increasing the dosage of C. Vulgaris, pyrolysis temperature drops and pyrolysis time increases, the average heating rate has the decreasing tendency. The maximum bio-oil yield and gas yield are achieved under 30g of C. Vulgaris and 25g of C. Vulgaris, respectively. The optimal content of activated carbon is 5% with the maximum gas yield of 60.25% and the largest weight loss of 87.47%.
