WebDuring the catalytic cracking reaction, a small part of the product gas was analyzed by an online quadrupole mass spectrum (HPR20, Hiden Analytical Inc.), which was used to monitor the hydrogen yield as a function of reaction time, and then the gas was collected by gas collection bags and analyzed by a micro-GC (TRACE 1300, Thermo Scientific) with … WebThe p660 form absorbs red light and is converted to the p73o form believed to induce a biological response. The P 7 3 0 form absorbs far-red and is converted to the inactive P 6 6 0 form. The P 7 3 0 form kept in the dark reverts to the P 6 6 0 form (Hendricks 1959). The action spectrum for photolability is seen in the lower part of Figure 9.
