MODELING OF A TiO2-COATED QUARTZ -WOOL PACKED-BED PHOTOCATALYTIC REACTOR

2010

A fixed-bed, photocatalytic laboratory reactor aimed to degrade pollutants from water streams was designed and built. Quartz wool coated with a thin film of TiO2 was employed as the reactor filling. The photocatalyst was placed in the reactor forming a loose packing to guarantee the intimate contact among reactants, photons, and the photocatalytic surface. This reactor was employed to study the photocatalytic decomposition of a model pollutant (formic acid). A reactor–radiation–reaction model was developed, which was comprised of the reactor mass balance, radiation model, and kinetic model for the degradation of formic acid. The local superficial rate of photon absorption, which was necessa…

Electrochemical conversion of carbon dioxide in pressurized electrochemical cells

2019

To limit the negative effect of carbon dioxide as a greenhouse gas, an interesting approach is the utilization of Carbon Capture and Conversion (CCC) methodology, which is focused on the use of CO2 waste as a feedstock to produce added-value products by using the excess electric energy from renewable source [1]. In this framework, an increasing attention has been devoted to the electrochemical conversion of carbon dioxide to formic acid in water [2-3] or CO [1]. Since the main hurdle of the CO2 reduction from aqueous solution is the low CO2 solubility in water, in this work, the utilization of pressurized electrochemical cells is evaluated. The effect of various operating parameters, includ…

2017

Electrochemical conversion of CO2 is considered one of the more appealing approaches to introduce renewable energy in the chemical and energy chain and to mitigate the greenhouse gases effect. In this work, the reduction of carbon dioxide was performed in undivided electrochemical cell to produce formic acid, which is one of the highest value-added chemicals and economically feasible for large-scale applications (1). It is well known that the main hurdle of the reduction of CO2 from water solution is the low CO2 solubility in water. In order to overcome this obstacle, a specific investigation on the effect of the CO2 pressure and other operating parameters at tin flat cathodes was carried o…

REDUCTION OF CARBON DIOXIDE TO FORMIC ACID IN VARIOUS KINDS OF ELECTROCHEMICAL DEVICES.

2016

The reduction of carbon dioxide is considered a relevant topic for both the synthesis of chemicals and/or fuels and the decrease of global warming. Indeed, the utilization of CO2 as a feedstock for producing chemicals may contribute to alleviate global climate changes caused by the increasing CO2 emissions and provide new opportunities for catalytic and industrial development. In the last years, an increasing attention has been devoted to the electrochemical conversion of carbon dioxide to formic acid or formate in water. Thus, formic acid has a broad market and wide application range in dyeing, textile and leather industries, in rubber production, as an intermediate in the chemical and pha…
