Paper Review

The amount of biomass products generated globally increases year after year. Nature produces lignocellulose, which is largely constituted of three components in the following order: cellulose (34–50%), hemicellulose (15–35%), and lignin (5–30%). A promising conversion method known as biomass conversion employs a liquid media-based process to address the issue of an abundance of biomass as waste. Converting biomass with ionic liquid (IL) can address not only environmental issues caused by the abundance of biomass waste but also generate new energy sources or new products with economical selling value. IL can be employed as a green catalyst, solvent, or electrolyte, as well as in a number of conversion processes. In general, 1-alkyl-3-methyl-imidazolium-based cations are the most commonly used IL types for biomass conversion. The conversion conditions are relatively mild, consisting of a low temperature of around 95-220 °C, 1 atm, for 10–240 minutes. This paper review is expected to be a significant reference in the future for the development of other biomass conversion processes.

Environmental issues make the quest for better and cleaner energy sources a priority. Worldwide, researchers and companies are continuously working on this matter, taking one of two approaches: either finding new energy sources or improving the efficiency of existing ones. Hydrogen is a well-known energy carrier due to its high energy content, but a somewhat elusive one for being a gas with low molecular weight. This review examines the current electrolysis processes for obtaining hydrogen, with an emphasis on alkaline water electrolysis. This process is far from being new, but research shows that there is still plenty of room for improvement. The efficiency of an electrolyzer mainly relates to the overpotential and resistances in the cell. This work shows that the path to better electrolyzer efficiency is through the optimization of the cell components and operating conditions. Following a brief introduction to the thermodynamics and kinetics of water electrolysis, the most recent developments on several parameters (e.g., electrocatalysts, electrolyte composition, separator, interelectrode distance) are highlighted.

The concern with global warming impacts on the environment has made the world population search for new energy sources that are less aggressive to the environment. Therefore, biodiesel has become more relevant and has expanded its proportion in the blend with diesel. However, Brazil still uses about 20% of bovine tallow, which emits large amount of GHG, degrades the soil and entails great water consumption. The purpose of this study was to evaluate the possibilities and effects of the substitution of this nonrenewable source for others of vegetable origin, as well as the environmental effects of increasing the percentage of biodiesel, reaching levels of 20% and 30%. Hence, two types of biodiesel were produced and tested, with and without bovine tallow, and the results obtained and data from the diesel fleet were used to model the impacts and CO2eq emissions with the aid of the MoMo Lite model in Brazil. It was possible to determine the great benefit of adopting higher levels of biodiesel in diesel (especially when there was a substitution of bovine tallow for plant sources), besides the importance of adopting broader analysis of the whole production cycle of the raw material. Since only CO2eq emission data were observed at the burning, the results varied only 10%, but when the results were analyzed through the well-to-tank, this variation rose to 52%.
