Development in TIPS RAS of novel advanced
processes for conversion of gaseous
feedstock and polymer wastes to valueadded chemical products
INOVACE 2013
Innovation technologies for unconventional chemical
feedstock transformation
1. New technology for synthesis gas production
2. New technology for production of olefins or
gasoline from natural , associated or biogas
3. New technologies for synthesis gas
transformation in slurry systems
4. Novel processes for polymer waste to fuel
transformation
OXIDATION OF NATURAL GASES TO SYN-GAS IN REACTOR SYSTEM WITH

Metal (Me)
Conversion hydrocarbons in syn-gas:
CnHm + nMeO → nCO + ½m H2 + nMe
CO2+CH4 = 2CO+2H2
Catalyst regeneration:
O2 + 2Me0 → 2MeO
Nitrogen
ADVANTAGES OF NEW TECHNOLOGY
OF SYNGAS PRODUCTION:
Air
•44 % less capital costs and 16% less syngas
production costs
in comparison to
traditional steam reforming;
•Processing of associated petroleum gas
with a wide range of C2-C4 hydrocarbons
and CO2 into synthesis gas ;
•Using air as an oxidant without dilution of
syngas with nitrogen;
•Elimination of the formation of explosive
oxygen-hydrocarbon mixtures;
•Low rate of catalyst deactivation due to
coke removal during regeneration;
•Production of considerable amounts of
pure nitrogen
