“…Meanwhile, C 2 H 4 and C 2 H 6 contents were small and thus had no apparent change. These results indicated that increasing the temperature is conducive to reforming reactions in equal (8). Notably, as the temperature increased, CH 4 content decreased from 11.24% to 3.83% and CO 2 content decreased from 20.04% to 2.40%, whereas CO content increased from 11.76% to 36.99%.…”

Rice husk was completely used for synthesis gas production. The pyrolysis volatiles (gas and bio-oil) of rice husk were used as raw materials to produce synthesis gas and the bio-char from the rice husk pyrolysis was used as the catalyst for catalytic reforming of pyrolysis volatiles of rice husk. We investigated the role of catalysts in gas and bio-oil catalytic reformation under different reaction conditions and the interaction between gas and bio-oil. The results indicated that 0.1Ni-0.1Co/RHPC (rice husk pyrolysis carbon) exhibited favorable selectivity and high conversion for rice husk pyrolysis volatiles. In particular, H 2 and CO contents from bio-oil were 56% and 18%, respectively, 37% and 36% from gas, respectively.Moreover, the content of H 2 is 32%, while that of CO is 22% after catalytic reforming from the mixture of gas and bio-oil. The Co-Ni/RHPC catalysts were characterized by X-ray diffraction, FT-IR, NH 3 -TPD, H 2 -TPR and N 2 adsorption and desorption. BET results showed that adding Co and Ni can effectively enhance the BET surface from 4 m 2 g À1 to 96 m 2 g À1 . XRD results showed the active parts of the Ni and Co diffraction peaks remained evident after reaction.

The chapter is devoted to the development of technologies for the processing of carbonaceous wastes, including hazardous ones, using plasma energy sources. In particular, plasma-steam equipment provides complete environmental safety and high quality of the synthesis gas produced. Its application is also discussed to exclude the risk of environmental pollution by heavy metals, if they are contained in the recycled waste. The advantages of using oxygen instead of air as an additional reagent in gasification processes are underlined. It is shown that the proposed variant of the processing technology corresponds well to the general idea of numerous publications in the world scientific literature, known as the Waste-to-Energy. It has been shown that plasma equipment has significant advantages in terms of the commercialization of processes for the treatment of sewage sludge and some other hazardous waste.

Kruopštus nuolatinės srovės elektros lanko reiškinių tyrimas, teorijos kūrimas ir pritaikymas, taip pat plazmos srautų diagnostika leido sukurti didelės galios ilgai veikiančius plazmos šaltinius. Atlikus tyrimus nustatyta, kad konvekcinis šilumos pernešimo intensyvumas plazmos generatorių lanko iškrovos zonoje yra tiesiog proporcingas elektrinio lauko stipriui, o intensyviausi šilumos mainai vyksta plazmotrono anode dėl čia lokalizuotos lanko dėmės ir jos aplinkoje vykstančios konvekcijos. Sukurti plazmos šaltiniai tiekia nepusiausvirąjį plazmos srautą, kurio tekėjimo charakteristikos gali būti griežtai reguliuojamos ir valdomos keičiant plazmotrono parametrus, įtekančių plazmą sudarančių ir papildomų dujų srautus bei įpūtimo vietų dislokaciją. Straipsnyje aptariami kai kurie žemos temperatūros plazmoje dominuojantys procesai, aprašomos naujos plazminės technologijos, sukurtos Lietuvos energetikos instituto Plazminių technologijų laboratorijoje: keraminių medžiagų lydymas ir pluošto sudarymas iš stiklo atliekų, korundo, dolomito, silicio dioksido ir jų mišinių; pavojingų medžiagų bei atliekų skaidymas plazmocheminiame sroviniame reaktoriuje; naujų katalizinių dangų iš pigių metalų oksidų sintezė ir panaudojimas vietoje įprastinių tauriųjų metalų dangų; konstrukcinių medžiagų paviršinių sluoksnių modifikavimas; C:H dangų nusodinimas iš įvairių plazmą sudarančių dujų mišinių. Aptartos kai kurios kitos technologijos ir naujos galimybės, pažymėta, kad atmosferinio slėgio nepusiausviroji plazma yra tinkama priemonė modifikuoti plačiai taikomas esamas medžiagas arba sintetinti naujas siekiant gauti specialios struktūros ir savybių produktus. Straipsnyje taip pat trumpai aprašoma nauja vandens garo plazminė technologija, kuri ateityje bus naudojama naudingų cheminių medžiagų sintezei, kuro konversijai, mikro- ir nanodalelių nusodinimui, įvairios paskirties katalizinių ir tribologinių dangų bei kompozitų sudarymui.
