Microalgal Biodiesel

Canada, as one of the largest producers and consumers of fossil fuels per capita on the planet, is attempting to reduce greenhouse gas (GHG) emissions. In order to accomplish this, fuel alternatives, such as biofuel, are required. Accordingly, this study uses LCA methodology to quantify the GHG impact of a unique biofuel production model. This unique model produces biodiesel (BD), acetone, butanol and ethanol (ABE) from microalgae and assesses the process GHG impact against other microalgal BD production processes. This study’s microalgal BD and ABE production process produces 76 kgCO2e per functional unit, whereas other comparable microalgal BD production processes produce between 3.7 and 85 kgCO2e. Overall, this study clarifies that without the development of versatile infrastructure to accommodate biofuel production, LCA studies will continue to find renewable fuel production processes net GHG positive for the simple reason that fossil resources are still the primary energy source.

The purpose of the work is to carry out a preliminary feasibility study of some typical projects on the production and consumption of agribiomass briquettes in Ukraine. The task of the work is to analyse and summarize the results of the feasibility study. The research methods include an overview of the successful examples of the production and use of biomass briquettes in Ukraine, the identification of priority types of relevant projects, the assessment of the main technical and economic indicators of several typical bioenergy projects. The results of the work make it possible to conclude whether it is feasible or not to implement certain types of projects in this segment of bioenergy. It is shown that today in Ukraine there are already examples of successful implementation of projects on the production and consumption of different biomass type briquettes. These examples include projects implemented for grants and business projects. For Ukraine, several promising options for the production and use of biomass briquettes can be suggested. The three typical variants of the biofuel production projects are as follows: (1) a rural enterprise produces agribiomass briquettes and sells them as a substitute for expensive coal to the local population and other consumers using small boilers with manual loading; (2) villagers or members of a united territorial community create an energy cooperative within which they produce biomass briquettes for their own consumption; (3) a large agrarian enterprise produces briquettes from its own agricultural raw materials and sells the product partly to its employees, partly to other consumers. Typical types of projects for the use of biomass briquettes can be as follows: an individual consumer or a trade/service organization or an industrial/commercial enterprise uses biomass briquettes in an existing boiler (replacement of coal) or in a newly purchased boiler of the appropriate capacity (replacement of coal/natural gas). The results of the preliminary feasibility study of these typical projects show that all the projects are economically feasible with a discounted payback period of 3-5 years.

Isentropic compressibility is one of the significant properties of biofuel. On the other hand, the complexity related to the experimental procedure makes the detection process of this parameter time-consuming and hard. Thus, we propose a new Machine Learning (ML) method based on Extreme Learning Machine (ELM) to model this important value. A real database containing 483 actual datasets is compared with the outputs predicted by the ELM model. The results of this comparison show that this ML method, with a mean relative error of 0.19 and R 2 values of 1, has a great performance in calculations related to the biodiesel field. In addition, sensitivity analysis exhibits that the most efficient parameter of input variables is the normal melting point to determine isentropic compressibility.

Recent Advances

With the global biodiesel production growing as never seen before, encouraged by government policies, fiscal incentives, and emissions laws to control air pollution, there has been the collateral effect of generating massive amounts of crude glycerol, a by-product from the biodiesel industry. The positive effect of minimizing CO2 emissions using biofuels is jeopardized by the fact that the waste generated by this industry represents an enormous environmental disadvantage. The strategy of viewing “waste as a resource” led the scientific community to propose numerous processes that use glycerol as raw material. Solketal, the product of the reaction of glycerol and acetone, stands out as a promising fuel additive capable of enhancing fuel octane number and oxidation stability, diminishing particle emissions and gum formation, and enhancing properties at low temperatures. The production of this chemical can rely on several of the Green Chemistry principles, besides fitting the Circular Economy Model, once it can be reinserted in the biofuel production chain. This paper reviews the recent advances in solketal production, focusing on continuous production processes and on Process Intensification strategies. The performance of different catalysts under various operational conditions is summarized and the proposed industrial solketal production processes are compared.
