METHODS FOR PREPARATION OF ALKANE AROMATIZATION CATALYSTSThe present invention relates to a process for the preparation of a catalyst for the aromatization of alkanes giving a high percentage conversion, a high yield, a high selectivity of aromatic compounds and a high selectivity of p-xylene in ...
Step-by-Step Solution1. Preparation of Alkanes: a. Hydrogenation of Unsaturated Hydrocarbons: - Alkenes and alkynes can be converted into alkanes through hydrogenation. - For exa
A geochemical investigation in the study area should be primarily focused on characterizing the complex chemical inventory of the groundwater, surface water, soil, rock, stream and lacustrine sediments, and soil gas. Geochemical site characterization inc
An examination of the kinetics of CpCo- alkane (PE oligomer) reactions revealed no bias for alkanes of differing molecular weights. However, the success of the LIAD/CpCoCI technique was found to depend greatly upon the LIAD sample preparation method used. Several sample preparation methods were ...

The ultimate source of SCVF emissions is subsurface natural gas resources. While methane is the predominant component of natural gas, there is considerable variability in the concentrations of methane, higher alkanes and other constituents dependent on the maturity and history of the reservoir (Hitcheo...

In terms of their molecular structures, VOCs can be divided into alkanes, olefins, aromatics, alcohols, aldehydes, and ketones (Zhu et al., 2020). In addition, according to the Kyoto Protocol (Eyckmans and Hagem, 2011), greenhouse gases are mainly divided into CO2, CH4, N2O, hydro...
(OSME) and GC-MS. 80 volatiles in total were identified through OSME, and 65 compounds in total were detected via the chromatographic analysis, while 44 with certain odor and 36 without odor. The detected compounds were mainly aldehydes, alkanes, carboxylic acids, alcohols and ketones (Dias ...
