Process simulation of bioethanol production from brown algae

An Overview of Bioethanol Production From Algae

Bioethanol production from marine algae biomass: prospect and troubles

The increase of petroleum cost as well as global warming and climate change result in investigation to discover new renewable energy resources. Bioenergy is one of the most important sources that is concerning the scientists and industrial sector. Although bioethanol had to be known as one of the most important renewable energy sources in order to reduce greenhouse gases and global warming, the...

Integrated bioethanol and protein production from brown seaweed Laminaria digitata.

A wild-growing glucose-rich (i.e. 56.7% glucose content) brown seaweed species Laminaria digitata, collected from the North Coast of Denmark in August 2012, was used as the feedstock for an integrated bioethanol and protein production. Glutamic acid and aspartic acid are the two most abundant amino acids in the algal protein, both with proportional content of 10% in crude protein. Only minor pr...

Process engineering economics of bioethanol production.

This work presents a review of studies on the process economics of ethanol production from lignocellulosic materials published since 1996. Our objective was to identify the most costly process steps and the impact of various parameters on the final production cost, e.g. plant capacity, raw material cost, and overall product yield, as well as process configuration. The variation in estimated eth...

Bioethanol : Industrial production process and recent studies

Because of the recent increase in the gas price and interest in environmental issues, the demand of ethanol as substitute of gasoline is rapidly increasing. Basically, 5 steps are included in ethanol production composed of grinding, cooking, fermentation, distillation, and hydration. In each step, there are several ideas to improve its productivity and benefitablity. In this paper, I put some e...
