Tungsten trioxide nanoparticles with two different sizes (average particle sizes about 50 and 80 nm) were prepared by the spray pyrolysis method. Photo degradation of Congo Red (azo dye) showed that photo catalytic property of the as-prepared WO3 nanoparticles with average size about 80 nm is higher than the sample with average size about 50 nm. Photo degradation of Rhodamine B (...

Renewable energy and alternative fuel from different conventional resources such as biomass, plastic waste, recyclable polymers are impertinent environmental issues worldwide. Furthermore, to replace fossil reduce greenhouse gas emissions that have a negative impact on climate change. This article exhibits the effect of metal oxide composite/clay in thermal decomposition Polypropylene. That het...

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...

This contribution is based on the monograph entitled “Recent Advances in Thermochemical Conversion of Biomass”, covering both general items as well as the primary processes, like fast pyrolysis, gasification, hydrothermal liquefaction, carbonization and secondary processes, like co-processing of bio-oil in fluidized catalytic cracking (FCC), Fischer-Tropsch synthesis and valorization of lignin ...
