In this contribution we report on the electrocatalytic reduction of CO2 for the production of liquid fuels by using two different approaches under i) liquid and ii) gas phase conditions. The main aim of the work is the comparison of these two experimental setups, in terms of productivity, kinds of liquid compounds produced and efficiencies, due to the differences in the mechanism which underlay...

This review presents the summary of new studies on pyrolysis of biomass to produce fuels and chemical feedstocks. A number of biomass species, varying from woody and herbaceous biomass to municipal solid waste, food processing residues and industrial wastes, were subjected to different pyrolysis conditions to obtain liquid, gas and solid products. The results of various biomass pyrolysis invest...

Liquid fuels(hydrocarbon and peroxide)are flammableand there is a risk of pool fires during their storage and transportation. In order to measure and develop effective methods for protection and considering safety distances, experimental studies and CFD simulations of pool fire of two hydrocarbon fuels (i.e. gasoline and kerosene) and peroxide (TBPB (tert-butyl peroxybenzoate)) were performed. ...

The conversion of CO2 with CH4 into liquid fuels and chemicals in a single-step catalytic process that bypasses the production of syngas remains a challenge. In this study, liquid fuels and chemicals (e.g., acetic acid, methanol, ethanol, and formaldehyde) were synthesized in a one-step process from CO2 and CH4 at room temperature (30 °C) and atmospheric pressure for the first time by using a n...

In 2008, the world produced approximately 87 gigaliters of liquid biofuels, which is roughly equal to the volume of liquid fuel consumed by Germany that year. Essentially, all of this biofuel was produced from crops developed for food production, raising concerns about the net energy and greenhouse gas effects and potential competition between use of land for production of fuels, food, animal f...

The electrocatalytic reduction of carbon dioxide (CO2) to liquid fuels has tremendous positive impacts on atomospheric carbon balance and help to reduce global warming issues. This paper reviewed current knowledge of electrochemical CO2 reduction to small organic molecule fuels on metal catalysts and gas-phase CO2 reduction techniques based on gas diffusion electrode and solid polymer electroly...

The combustion of fuels, aside from their state concentrations (solid, liquid, gas), always occur in the gas phase. Next gas phase which is the mixture of the fuel and air or the fuel and oxygen, as well as of the fuel and gases containing oxygen can occurs in the form premixed homogeneous or not premixed heterogeneous. Processes of the combustion of liquid fuels and solid are more complicated ...
