Characterized the microalgae (Chlorella and Spirulina) and macro algae by using TGA and bomb calorific meter for the biomass energy application

Abstract

Biomass usually is noticed a composition of various types of waste materials that can be utilized as useful form of energy alternative to the conventional fossil fuels. However this new kind of energy hasn't met its full potential in production of energy especially electricity generation due to its lower performance in terms of thermal efficiency. Algae (included Microalgae & Macroalgae) is widely used for multi-application developments such as fishery aquaculture, food/nutrient supplement, cosmetics, and biomass energy. Microalgae has been treated as the source of bio-fuel. In this paper we selected the two type of freshwater microalgae "Chlorella Vulgaris " & "Spirulina " and macro algae (Laminariaceae) as the main materials and we analyzed TGA (Thermal Gravity Analysis) and calorific values (heat of combustion). We found the calorific values are 1000∼5000 KC/KG and TGA results show that the microalgae decrease rapidly after reached 300 °C. The results in this paper will be used as a reference material for microalgae multi-oriental energy application and biomass composition proximate and ultimate research development in the future.
