In-bulk recording without cracking in borosilicate glass by high repetition rate (80 MHz) 12 ps pulses at 355 nm wavelength is demonstrated and discussed. The theoretical model of a “hot-line” scan and thermal accumulation qualitatively well describes the experimental results. The analytical expression of a thermally induced stress was obtained. © 2004 American Institute of Physics. [DOI: 10.10...

Biomass is one of the most important sources of renewable energy. One aim of Biomass gasification is to convert a solid feedstock into a valuable syngas for electricity or liquid fuel production. Actual industrial auto-thermal gasification processes achieve a production of syngas mainly polluted by products such as dust, nitrogen oxides, sulfur dioxide and tars. Tars remain, one of the main dra...

Many organic-rich rocks are major sources of oil and gas in sedimentary basins presumably through high-temperature thermal cracking. This view was brought into question with recent reports of marine shales generating catalytic gas in the laboratory at 50◦C, 300◦C below thermal-cracking temperatures. Gas forms under natural conditions without artificial stimulation. Compositions of methane, etha...

Some the same as furnace at time replace reactor doing In oven placed serpentine of pipes beginning part it heats up. Next cracking process goes.
