“…Several conventional conversion methods 8 have already been proposed for the decentralized generation of pure hydrogen from biogas, such as steam reforming, 9 dry reforming and autothermal reforming, 10,11 but also unconventional methods, such as solar reforming, membrane reforming 12 and thermal plasma reforming. However, these methods for hydrogen generation from biogas may be inhibited by the presence of common impurities as H 2 S which poisons downstream nickel-based catalysts, siloxanes or carbon depositions due to methane dry reforming with carbon dioxide.…”

“…Oxygen reforming emits heat to provide the heat required for water reforming and the subsequent autothermal reaction. In addition, increasing the ratio of oxygen/carbon can release a large amount of heat during combustion and, thus, improve both the temperature of the reaction system and hydrogen yield; however, if too much oxygen is used, it will react with hydrogen and result in a decreased hydrogen yield. − …”

Non-precious metal catalysts were prepared using the equal volume fractional impregnation method. The effect of the catalyst bed inlet temperature and diesel liquid airspeed on the self-thermal reforming of diesel was investigated with respect to the LaCeCoCrFeNi/Al2O3 catalyst. Optimum operating conditions were determined with a catalyst bed inlet temperature of 700 °C, diesel liquid airspeed of 0.24 h–1, water and carbon ratio of 15, and oxygen/carbon ratio of 0.4.

“…These advantages lead to a minimum risk of coking on the surface and blocking the pores of catalysts. 5,6 The hydrogen production from methanol can be achieved by using auto-thermal reforming of methanol (ATM), 7,8 methanol steam reforming (MSR), 9,10 partial oxidation of methanol (POM), 11,12 and methanol decomposition (MD). 13 At present, MSR is the main thermochemical route for hydrogen production from methanol.…”

Hydrogen production via partial oxidation of methanol (POM) in an ultrasonic spray system was studied experimentally, using an h-BN-Pt/Al 2 O 3 catalyst with ultra-low Pt contents (0.2 wt%). The effects of oxygen-to-methanol (O 2 /C) ratio, methanol flow rate, and gas hourly space velocity (GHSV) of air and carrier gas on H 2 yield were examined. Compared to conventional spray systems, the ultrasonic spray system could produce more uniformly dispersed methanol and thus further enhance the POM reaction. The results showed a higher O 2 /C ratio (0.8) enhanced the POM, which poses higher CH 3 OH conversion, higher reaction temperature, and lower CO and CH 4 productions. The CO 2 concentration was mainly affected by GHSV and CH 3 OH flow rate. A higher GHSV led to a quicker retention time for the reactants in the catalyst bed, and a lower CH 3 OH flow rate deteriorates the CO 2 concentration. Based on the Box Behnken design (BBD) from response surface methodology (RSM) and analysis of variance (ANOVA), the optimal operating conditions are found to be O 2 /C ratio = 0.8, CH 3 OH flow rate = 0.7 mL min À1 , and GHSV = 10 000 h À1 . Combining these conditions, the predicted maximum H 2 yield is 1.635 mol‧(mol CH 3 OH) À1 which is close to the experimental value of 1.646 mol‧(mol CH 3 OH) À1 . The RSM and ANOVA not only resulted in a quadratic response surface regression model and significant regression coefficients but also indicated CH 3 OH flow rate being the primary factor.analysis of variance (ANOVA), h-BN-Pt/Al 2 O 3 catalyst, hydrogen production, partial oxidation of methanol (POM), response surface methodology (RSM), ultrasonic sprays
