Biokonwersja gliceryny odpadowej do wodoru przez bakterie Enterobacter aerogenes
PublicationBadano możliwości produkcji wodoru w procesie ciemnej fermentacji beztlenowej z pożywki tioglikolanowej z dodatkiem gliceryny przez bakterie Enterobacter aerogenes. Przetestowano stanowisko umożliwiające prowadzenie fermentacji, odbiór i analitykę produktów lotnych i medium ciekłego. Uzyskano dobrą powtarzalność doświadczeń. Stwierdzono, że gliceryna jest trudniej przyswajalna przez bakterie niż np. glukoza, stąd ilość gazu powstającego...

Bioconversion of waste materials to hydrogen via dark fermentation using Enterobacter aerogenes
PublicationHydrogen can be obtained via dark fermentation with the use of anaerobic Enterobacter aerogenes. The efficiency of hydrogen production by fermentation techniques is strongly dependent on the con-ditions used i.e. the pH range, temperature, composition of fermentation broths, oxygen content, or even the presence of substances with potentially inhibitory effects on the microbiological culture [1-4]. The paper describes the study...

Biokonwersja materiałów odpadowych do wodoru na drodze fermentacji ciemnej z wykorzystaniem Enterobacter aerogenes
PublicationW drodze fermentacji ciemnej z wykorzystaniem względnych beztlenowców z gatunku Enterobacter aerogenes można otrzymać wodór. Wydajność wytwarzania wodoru technikami fermentacyjnymi jest silnie zależna od zastosowanych warunków w zakresie pH, temperatury, składu brzeczek fermentacyjnych, zawartości tlenu czy nawet obecności substancji o potencjalnie inhibitującym wpływie na hodowlę mikrobiologiczną [1-4]. W pracy opisano badania...

A comparative study of pentanol (C5 alcohol) and kerosene blends in terms of gas turbine engine performance and exhaust gas emission
PublicationThe growing demand for sustainable and clean energy sources provides the incentive for the development of alternative fuels. Simultaneously, the development of gas turbine technologies with flexible fuel supply systems enables the use of alternative non-fossil fuels that can play key roles in contributing to global efforts in meeting emissions targets. This paper presents the current state of knowledge on the production and potential...

Hydrogen Production from Energy Poplar Preceded by MEA Pre-Treatment and Enzymatic Hydrolysis
PublicationThe need to pre-treat lignocellulosic biomass prior to dark fermentation results primarily from the composition of lignocellulose because lignin hinders the processing of hard wood towards useful products. Hence, in this work a two-step approach for the pre-treatment of energy poplar, including alkaline pre-treatment and enzymatic saccharification followed by fermentation has been studied. Monoethanolamine (MEA) was used as the...

Research on Tool Temperature Dependence on Lapping Grains Size
PublicationCommonly used as a finishing operation, lapping has been used for achieving ultra-high finishes and close tolerances between mating pieces. Its carried out by applying loose abrasive grains between work and lap surfaces, and causing a relative motion between them resulting in a finish of multi-directional lay. The grains activity (sliding and rolling) in the working gap causes not only the material removal but also the temperature...

Fermentative Conversion of Two-Step Pre-Treated Lignocellulosic Biomass to Hydrogen
PublicationFermentative hydrogen production via dark fermentation with the application of lignocellulosic biomass requires a multistep pre-treatment procedure, due to the complexed structure of the raw material. Hence, the comparison of the hydrogen productivity potential of different lignocellulosic materials (LCMs) in relation to the lignocellulosic biomass composition is often considered as an interesting field of research. In this study,...

Kontrola procesu wytwarzania biowodoru z gliceryny podczas fermentacji beztlenowej
PublicationProdukcja wodoru z biomasy z wykorzystaniem procesów biologicznych jest korzystną ekonomicznie alternatywą w porównaniu do otrzymywania wodoru np. na drodze zgazowania, pirolizy, czy przez rozkład biomasy w warunkach nadkrytycznych. Wśród biologicznych procesów otrzymywania wodoru, za najbardziej obiecującą uważa się ciemną fermentację wodorową, w której substraty organiczne są przekształcane bez udziału światła przez bakterie...
