The work presented here, demonstrates the on-board exhaust assisted catalytic ammonia (NH3) conversion to H2-N2 using either only heat (decomposition) or by direct reaction with part of gas (reforming). resultant mixture from driven thermochemical energy recovery processes contains up 15% more than reactant NH3 (i.e. for 1 kW used in 1.15 H2 is produced). Experimental studies a rhodium-platinum...

Asymmetric hydrogenation uses inexpensive, clean hydrogen gas and a very small amount of a chiral molecular catalyst, providing the most powerful way to produce a wide array of enantio-enriched compounds in a large quantity without forming any waste. The recent revolutionary advances in this field have entirely changed the synthetic approach to producing performance chemicals that require a hig...

The clean hydrogen in the prioritized value chain platform could provide energy incentives and reduce environmental impacts. In current study, strengths, weaknesses, opportunities, threats (SWOT) analysis has been successfully applied to different sectors determine Japan’s chain’s as a case study. Japan was chosen study since we believe that it is only pioneer country with national strategy, in...

The reaction of 3-chloropropyl boehmite nanoparticles with caffeine and sulfuric acid afforded BNPs-3-propyl-imidazolopyridinium hydrogen sulfate [BNPs-Caff]HSO4 as a new BNPs-supported ionic liquid (IL) catalyst. [BNPs-Caff]HSO4 proved to be an efficient heterogeneous catalyst for the synthesis of pyrazolopyranopyrimidines via a one-pot four-component reaction of...
