Interestingly, ethane (C2H6) is produced when the roughness factor exceeds 30 (FEC2H6 = ~1.2% in this work). The mechanistic pathway to produce C2H6 has been proposed to be the reaction between adsorbed ethylene (*C2H4) and adsorbed hydrogen (*H)51. Therefore, observation of C2H6 indic...
C. Natural gas contains methane, ethane and hydrog How many moles of gaseous boron trifluoride, BF3, are contained in a 4.3409 L bulb at 790.5 K if the pressure is 1.215 atm? How many grams of BF3? Calculate the final pre...

combined ethylene and propylene content greater than 30 percent by weight; (d) a combined ethane and propane content less than 50 weight percent; (e) a methane content less than 15 weight percent; (f) a combined saturated and unsaturated C4 and higher hydrocarbon content less than 20 ...
Olefins used in the process of this invention can be in the presence of other substances such as other hydrocarbon-based molecules. Thus, a feedstream used in the process of this invention comprising propylene also can contain other hydrocarbons such as methane, ethane, propane, hydrogen, and in...
A test was conducted where a mixture of methane and propane was converted to ethane at 250掳, with almost 100% selectivity. The results indicated that methane can replace hydrogen to cleave carbon-carbon bonds, saving costs and providing environmental benefits. The new catalyst may impart a ...
