While methane (CH 4 ) is always a major constituent of the gas, other components may be present: hydrocarbons heavier than methane (mostly ethane C 2 H 6 , propane C 3 H 8 , butane C 4 H 10 ), carbon dioxide CO 2 ; hydrogen sulfide H 2 S, nitrogen, hydrogen, argon, helium, ...
Here we report a promising LOHC system, based on the inexpensive, abundant 2-aminoethanol (AE), that is catalytically converted to a cyclic dipeptide with formation of hydrogen gas by use of a ruthenium pincer catalyst; peptide hydrogenation, using the same catalyst, regenerates AE. Mechanistic ...

It is process in order to raise the execution possibility of the hot gas cleanup in order to produce the synthetic gas, rich of hydrogen and carbon monoxide under the pressure which is sufficient in order to form the flow of the synthetic gas and at temperature, the flow of the methane ri...
The direct synthesis of hydrogen peroxide (H2O2) from H2 and O2 over gold nanoparticles has been achieved in the past decade; however, our understanding for the mechanism is still far from complete. We present herein a density functional theory investigation of the formation mechanism of H2O2 from...
When subjected to HPLT conditions, the water can physically absorb low-molecular-weight hydrocarbons (e.g., C1, C2, C3, iC4, nC4, iC5), CO2, and hydrogen sulfide (H2S) within its hydrogen-bonded solid lattice. Regardless of their state (i.e., vapor or liquid) and miscibility ...
Helium partitions into this gas phase. This gas formation mechanism accounts for the observed primary nitrogen–helium gas discovered in the basal sedimentary lithology of this and other basins, predicts co-occurrence of crustal gas-phase hydrogen, and reduces the flux of helium into overlying strata...
Methods and systems for treating a waste stream (202) in a waste treatment system (204) involve performing a unit process (206) by contacting the waste stream (202) with oxyhydrogen-rich gas (214) generated on-site by an oxyhydrogen gas generator (207). The gas generator (207) preferably...
