Name: Pyrolysis characteristics and kinetics of microalgae by Thermal Gravimetric Analysis (TGA)
SKU: STEM-ACT-0037-WXH
Rating: 5 (1 reviews)

Introduction

Pyrolysis is a promising route for biofuels production from microalgae at moderate temperatures (400–600 °C) in an inert atmosphere. Depending on the operating conditions, pyrolysis can produce biochar and/or bio-oil. In practice, knowledge for thermal decomposition characteristics and kinetics of microalgae during pyrolysis is essential for pyrolyzer design and pyrolysis optimization.

Principle

Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction).

Applications

• Thermal characterization of polymers.
• Determination of the composition of alloys and mixtures.
• Determining the purity and thermal stability of both primary and secondary standards.

Procedure

TGA analysis is performed by gradually raising the temperature of a sample in a furnace as weight is measured on an analytical balance that remains outside the furnace. Thermogravimetric analysis instrument measures the changes in a sample's weight in a particular temperature by enclosing the sample in an oven.
