Pyrolysis Process in Aramid Fibers Investigated by Py-GC/MS & TGA-DTA/MS

Poly （ m-phenylene isophthalamine） （PMIA） and Poly（ p-phenylene terphthalamine） （PPTA） are among the most important high-temperature resistant aramid fibers. The pyrolysis behaviors of these two fibers under inert gases were studied using pyrolysis-gas chromatography/mass spectrometry （Py-GC/MS） and thermogravimetric analysis coupled with mass spectrometry （ TGA-DTA/MS ）. The pyrolysis processes of PMIA and PPTA are distinguishing, and the stepwise pyrolysates reflect these differences. A mechanism system of pyrolysis is suggested, which involving hydrolysis and homolysis, At low pyrolysis temperatures, hydrolysis is a primary reaction, and it is very noticeable in the first-step pyrolysis region of PMIA. Elevating pyrolysis temperature, homolysis is enhanced and keep a large advantage in the high temperature range. On the other hand, at higher temperatures, carbonization happens and the homolysis and carbonization of PPTA are emphasized more than of PMIA.

Development of RSDS-III Technology for Ultra-Low-Sulfur Gasoline Production

The 3rd generation catalytic cracking naphtha selective hydrodesulfurization(RSDS-III) technology developed by RIPP included the catalysts selective adjusting(RSAT) technology, the development of new catalysts and optimized process conditions. The pilot plant test results showed that the RSDS-III technology could be adapted to different feedstocks. The sulfur content dropped from 600 μg/g and 631 μg/g to 7 μg/g and 9 μg/g, respectively, by RSDS-III technology when feed A and feed B were processed to meet China national V gasoline standard, with the RON loss of products equating to 0.9 units and 1.0 unit, respectively. While the feed C with a medium sulfur content was processed according to the full-range naphtha hydrotreating technology, the sulfur content dropped from 357 μg/g in the feed to 10 μg/g in gasoline, with the RON loss of product decreased by only 0.6 units. Thanks to the high HDS activity and good selectivity of RSDS-III technology, the ultra-low-sulfur gasoline meeting China V standard could be produced by the RSDS-III technology with little RON loss.

Contemporary myth and its aesthetic consciousness

Pragmatic rationality and scientific and technological developments in modem society have jointly put an end to classical myth and consigned it to the historical museum of the spiritual culture. However, mythical thinking and consciousness are synchronically hidden in our psychological structures and still exert an important influence on civilizations and cultures. In the modem and postmodem historical and cultural context, myth hides in our spiritual and cultural activities in various altered forms. Having evolved into a mythic form in the contemporary sense, it continues to play a powerful psychological role and to act as a midwife of conscious activities and forms. Contemporary myth typically comprises science myth, consumption myth and hero myth. It has inherited the symbols and structures of traditional myth, but with some developments and variations; in particular, by means of science and technology, it has acquired broader and richer social ingredients and swift and intensive modes of transmission, producing a widespread and far-reaching influence on various aspects of society.
