Abstract The utilization of real producer gases such as raw biogas or gasified wood for chemical looping hydrogen production implies the introduction harmful contaminants into process. Hydrogen sulfide represents one most challenging trace in reformer steam iron cycle. aim present work was an in-depth investigation reforming with pure methane and synthetic contaminated selective concentrations ...

The pyrolysis of lignocellulosic biomass is one the most promising methods alternative fuels production. However, due to low selectivity this process, quality obtained bio-oil usually not satisfactory and does allow for its direct use as an engine fuel. Therefore, there a need apply catalysts able upgrade composition mixture products. Unfortunately, despite increase in efficiency thermal decomp...

In recent decades, the massive emission of greenhouse gases, such as carbon dioxide and methane, into atmosphere has had a serious impact on ecological environment. The dry reforming methane to syngas cannot only realize resource utilization but also reduce global climate change. It is great significance in reduction. Owing (DRM) being strongly endothermic reaction, it needs be carried out unde...

New theoretical relationships for a complex catalytic reaction accompanied by deactivation are obtained, using as an example the two-step mechanism (Temkin–Boudart mechanism) with irreversible reactions and deactivation. In domain of small concentrations, Alim=NSk1CAkd, where Alim is limit integral consumption gas substance, NS number active sites per unit catalyst surface; k1 kd, kinetic coeff...
