Effect of hydrogen addition on the laminar premixed combustion characteristics the main components of natural gas

Laminar flame characteristics of natural gas and dissociated methanol mixtures diluted by nitrogen

“…The peak laminar burning velocity of DM0, DM40 and DM80 occurs at equivalence ratio of 1.0, 1.1 and 1.2 respectively. There is a trend that the peak burning velocity shifts towards the richer side with increasing fraction of dissociated methanol, which shows the similar trend with the results in [27] and [34]. From previous studies [35, 36 and 37], the peak burning velocity of H 2 -air mixtures and syngas (CO:H 2 =99:1)-air mixtures occurs at around the equivalence ratio of 1.8 and 2 respectively, while the peak laminar burning velocity of CH 4 -air mixtures occurs at around the equivalence ratio of 1.…”

Numerical Investigation of the Impact of H2 Enrichment on Lean Biogas/Air Flames: An Analytical Modelling Approach

“…It comprises 111 chemical species and 784 reactions and is tailored for the combustion of H 2 /CO/C 1 -C 4 based blends. This mechanism has overall presented good results with CH 4 /CO 2 /H 2 fuels in engine simulations [23] and in the estimation of laminar premixed combustion characteristics [24,25].…”

Adsorbed Natural Gas Storage for Onboard Applications

“…It should be noted that NG is a mixture that also contains light alkanes (e.g., ethane, propane, butanes), H 2 S, CO 2 , and N 2 . [ 10,16,34,39 ] These components can have an adverse effect on the methane storage and delivery capacity of the ANG system. [ 26,155 ] The composition of NG varies from one coal bed to another, [ 156–158 ] complicating the ANG system.…”

“…Among fossil fuels, natural gas (NG) is the best suited to satisfy the world's energy demand while minimizing environmental repercussions. [ 10–17 ] One advantage of NG is that its reserves could satisfy the global energy demand for the upcoming decades. [ 18,19 ] For instance, at the end of 2018, the world's proved NG reserves totaled about 197 trillion cubic meters.…”

“…[ 21 ] Second, as compared to coal and oil, NG has a higher calorific value and lower carbon emission. [ 10,16,22 ] In fact, NG combustion emits 50% and 33% less carbon dioxide (CO 2 ) than the combustion of coal and oil, respectively. [ 16 ] Considering the advantages of energy generation from NG, it is unsurprising that the IEA forecasted that the share of NG toward primary energy will continue to increase another 20 years until 2040.…”
