A slow pyrolysis of pinewood was investigated in this paper. Through the briquette process, the pinewood sawdust becomes molded biomass. The molded bio-char was produced from molded biomass with different pyrolysis factors, and the bio-char’s heating value, char yield rates, and physicochemical and morphological properties were investigated. Molded bio-char’s characteristics depended principall...

Waste to energy is an answer to the growing demand for fossil fuels. Pyrolysis plays an important role in waste to energy technologies. The product obtained from pyrolysis depends on various physical parameters that influence the reaction mechanism. Pyrolysis reactions can be classified onto flash, fast and slow pyrolysis depending on temperature and heating rate. This paper discusses the effec...

As the production process continues to be refined, biomass pyrolysis oils are increasingly being considered as potentially feasible renewable fuels. Combustion of pyrolysis oils in diesel engines has been scarcely studied, and the few studies which have been performed indicate that these fuels exhibit excessively long ignition delay, rendering them dependant on auxiliary ignition sources for di...

the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

Avoiding irreversible climate change requires >50% reduction in anthropogenic greenhouse gas (GHG) emissions by the year 2050 and the net removal of GHGs from the atmosphere by the end of the 21st century. This challenge is particularly daunting given that energy derived from fossil fuels is at the core of all modern economies and some sectors of the economy, such as transportation, will be alm...

Pyrolysis oil from the slow pyrolysis of German brown coal from Schöningen, obtained at a temperature of 500°C, was separated and analyzed using hyphenation of gas chromatography with an atmospheric pressure chemical ionization source operated in negative ion mode and Fourier transform ion cyclotron resonance mass spectrometry (GC-APCI-FT-ICR-MS). Development of this ultrahigh-resolving analysi...

Two solution-based methods, metallo-organic decomposition and sol–gel processes, were used to study the effects of precursor solution type on the microstructure evolution and texture development of oriented PZT films. Microstructure development and perovskite content are strongly dependent on the heating rate. Fast heating rate forms a dense fine-grained microstructure with (111) orientation. I...
