Analysis of hydrocarbons and ash particles formed from contaminated industrial biowaste under combustion-like conditions
Kozinski, Janusz A.,Zheng, Guohui,Uloth, Vic,Gangli, Peter,Hutny, Wes
, p. 4318 - 4325 (1999)
A concept of multizone combustion of pulp and paper-generated biowaste was investigated. The biowaste was initially fed into the low-temperature region (1250 K) and then subjected to the high-temperature treatment (1770 K), which was followed by sudden quenching in a second lowtemperature zone (1250 K). This type of burning is called the low-high-low temperature process (LHL). It was found that destruction of selected polycyclic aromatic compounds occurred during the LHL process before they were emitted into the atmosphere. The biowaste material underwent dramatic morphological changes, which influenced segregation of metals within ash particles and their leachability. The heavy metals (Cr, Cd, Pb) were encapsulated and immobilized within the ash particle core surrounded by a compact shell consisting of condensed layers of light nonhazardous metals (Si, Al, Na, K). It seems that the multizone combustion of biowaste may be an attractive and useful way for the clean and efficient disposal of contaminated biowastes.

Paragraph 0058; 0059; 0062; 0063, (2017/05/02)
The present invention relates to a 1, 5, 9-trisubstituted coronene compound and a synthesis method thereof. The structural formula of the compound is shown in img file = 'dest _ path _ image 001. TIF 'wi = '109 'he = '108', wherein R represents H, C1-C18 alkyl, phenyl, 4-methylphenyl, 4-methoxy phenyl, benzyl, cyclohexyl, 4-trifluoromethylphenyl, thiophene, furan and the like. According to the technical scheme of the invention, the easily prepared 1, 5, 9-triamido triphenylene is subjected to diazotization and halogenation reaction to obtain the tri-halogenated triphenylene. After that, the tri-halogenated triphenylene is subjected to Sonogashira reaction with various alkynes to generate atriyne-triphenylene compounds. Finally, through the metal-catalyzed reaction and the cyclization reaction under the effect of an organic base, various 1, 5, 9-trisubstituted coronene compounds, novel in structure, can be obtained. According to the technical scheme of the invention, raw materials are easy for mass preparation. Meanwhile, the synthesis step is relatively short and the operation is convenient. The obtained trisubstituted coronene compound is good in thermal stability and chemical stability, and the trisubstituted coronene emits the relatively strong fluorescence within the range of 420-550 nm according to the fluorescence emission spectrum of the trisubstituted coronene compound. Therefore, the trisubstituted coronene is an excellent fluorescent material for preparing UV ultraviolet charge-coupled devices (UV-CCD) and organic light-emitting diodes (OLEDs), and has a wide application prospect in the field of electronic materials.
