Abstract. In this study, we present simultaneous airborne measurements of peroxyacetyl nitrate (PAN), ethane (C2H6), formic acid (HCOOH), methanol (CH3OH), and ethylene (C2H4) above the South Atlantic in September October 2019. Observations were obtained from Gimballed Limb Observer for Radiance Imaging Atmosphere (GLORIA), as two-dimensional altitude cross sections along flight path. The fligh...

Ammonia as a fuel offers the potential to avoid carbon emissions, but its combustion is hindered by low reactivity. Here, extinction limits of NH3 and plus reactivity enhancers were measured in counterflow laminar non-premixed flames. A stable NH3-N2 flame was established with an oxygen-enriched oxidizer stream, when blended CH4, C2H6, C3H8, H2. For mixtures, results showed that CH4 has least e...

We used the NIRSPEC instrument on the Keck-2 telescope atop Mauna Kea, HI to observe Comet C/2001 A2 (LINEAR) in a Target of Opportunity campaign on UT 2001 July 9.5, 10.5 August 4.4, 10.5. We measured seven organic parent volatiles (C2H6, C2H2, HCN, CH4, CO, CH3OH, H2CO) simultaneously with H2O. We obtained absolute production rates and relative abundances for parent volatiles, and also measur...

The Cassini measurements of C2H2 and C2H6 at ∼5 mbar provide a constraint on meridional transport in the stratosphere of Jupiter. We performed a two-dimensional photochemical calculation coupled with mass transport due to vertical and meridional mixing. The modeled profile of C2H2 at latitudes less than 70 follows the latitude dependence of the solar insolation, while that of C2H6 shows little ...

The separation of light hydrocarbon mixtures and the extraction C3H8 C2H6 from natural gas are significant importance in purification upgrading. Microporous carbon adsorbents promising separation. However, fabrication uniform ultramicropores to boost selectivity remains challenging. Herein, we fabricated a series poly(vinylidene chloride)-resin-derived ultramicroporous with relatively pore size...
