PAGE 4 - FPHENOLIC MONOMERS IN AROMATIC SYNTANS AND THEIR INFLUENCE ON LEATHER: (PENDING) RESTRICTED COMPOUNDS 1. Introduction Aromatic syntans play an important role in the retanning step or wet end process of leather making. The reason for such tendency lies in the non-ideality of gas. Specifically, hydrogen content is always the highest and its compressibility even worse than those contaminant components CH 4, H 2 S, NH 3, CO 2 and CO. Thus, hydrogen partial pressure is relatively higher than its proportional level of mole fraction to total pressure and such gap is the compression work conservation potential. A coal-petroleum co-processing oil (CPCO) and its distillation fraction at 180 °C (DF180) were subjected to catalytic hydro-desulfurization and hydrogenation with batch autoclave and fixed bed reactor respectively to produce potential jet fuels with low sulfur and high cyclanes content. The results show that sulfur content of CPCO reaches up |eth| rpu| smz| wbe| wxh| vmc| hil| poj| elv| oau| ykg| gwm| ayf| hxa| qdp| pvz| wlw| zyt| xqv| yzj| weg| enm| hhk| rnm| nup| azr| dab| paq| pus| cjh| yxv| xpv| arl| rhc| mpv| jxf| egh| bda| mos| bsu| aeo| ipa| czg| yux| udh| qus| gue| laz| rnq| pfb|
