FATTY ACID CONVERSION OVER POLYMER-BASED CATALYSTS SYNTHESIZED IN SUBCRITICAL WATER (Papers SGEM2018)

V. Matveeva, A. Stepacheva, V. Molchanov, G. Demidenko, M. Sulman
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Conversion of vegetable oils and fats are of the great attention in the last decades. The main processes used in the triglyceride processing are transesterification, hydrolysis, hydrodeoxygenation, and hydrogenation. The last two reactions can be concerned with hydrotreatment (...)


FOSSIL FUEL IN CONTRAST WITH RENEWABLES IN ROMANIA (Papers SGEM2018)

A. M. BULMEZ, I. Bucur, P. Gabriel
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Renewable-energy sources are considered to be the energy that is collected from sources that may be regenerated in a lifetime. The renewable-energy sources branch out in five types: wind power, hydropower, solar energy, geothermal energy and bio energy. However, in this paper, we are (...)


HARNESSING HYDROPOWER IN NORTH-EASTERN POLAND (Papers SGEM2018)

P. Solowiej, J. Piechocki, M. Neugebauer, K. Nalepa, M. Wesolowski
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Poland has been long harnessing hydraulic energy despite the absence of supportive conditions for hydropower development. According to the Energy Regulatory Office, there were 721 hydropower plants in Poland in 2014. Electric power generation in small and medium-sized hydropower (...)


HARVESTING GEOTHERMAL FROM ABANDONED, SUPERDEEP DRY HOLES (Papers SGEM2018)

M. Horvath, D. Kelemen, A. Toth, D. K. Fenerty
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Hungary, like other eastern European countries, has suffered from an energy deficit for the past several years. Energy consumption exceeds energy production, and the country remains dependent on mostly imported fossil fuels such as oil and gas. Renewable energy usage is mostly limited (...)


HYDROGENATION OF LEVULINIC ACID USING MONO- AND BIMETALLIC POLYMER-BASED RU-CONTAINING CATALYSTS (Papers SGEM2018)

E. Sulman, D. Abusuek, L. Nikoshvili, O. Manaenkov, L. Kiwi-Minsker
Thursday 11 October 2018 by Libadmin2018
ABSTRACT This work is devoted to the investigation of the possibility of use of Ru-containing catalysts including bimetallic (Ru-Fe) magnetically separable one on the basis of polymeric matrix of hypercrosslinked polystyrene in hydrogenation of levulinic acid (LA) to gamma-valerolactone (GVL), (...)


IMPROVING THE ENERGY EFFICIENCY OF MULTIFUNCTION MOTOR VEHICLES BY EQUIPPING THEM WITH HYDROSTATIC PUMPS WITH LOAD SENSING (Papers SGEM2018)

P. A. Chirita, C. Cristescu, L. Dumitrescu, A. D. Marinescu, C. A. Safta
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Multifunctional motor vehicles are equipped with one or more working mechanisms actuated by hydrostatic drive systems, which consume most of the power installed on such vehicles in which the primary mechanical energy is generated by an internal combustion engine, usually Diesel (...)


INCREASING ENERGY EFFICIENCY AND FLOW RATE REGULARITY IN FACILITIES, MACHINERY AND EQUIPMENT PROVIDED WITH HIGH OPERATING PRESSURE AND LOW FLOW RATE HYDRAULIC SYSTEMS (Papers SGEM2018)

T.C. Popescu, P.A. Chirita, A.I. Popescu
Thursday 11 October 2018 by Libadmin2018
ABSTRACT There are plenty of facilities, machinery and equipment, either stationary or mobile, which require hydraulic operating power, generated by low-flow pumping systems at high pressures. Such systems can be met in stationary applications, in which energy efficiency is important, while (...)


INCREASING PERFORMANCES OF A COMBINED HEAT AND POWER PLANT BY OPTIMAL TECHNOLOGY SELECTION AND OPERATION (Papers SGEM2018)

D. TUTICA, V.CENUSA, P. TUDOR, R. PATRASCU, E. MINCIUC
Thursday 11 October 2018 by Libadmin2018
ABSTRACT The efficient use of cogeneration systems depends on both the heat demand variations and on the restrictions imposed by the related legislation. In this paper, in order to optimize the operating regimes of a Combined Heat and Power Plant, authors have determined the correlation (...)


INFLUENCE OF SUPPORT SCHEME ON ELECTRICITY PRODUCTION FROM RES IN ROMANIA (Papers SGEM2018)

B. Popa, L. I. Vuta, F. Popa, M. A. Diminescu, E. I. Tica
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Renewable energy sources (RES) are of great interest across the world, since it can be used to obtain clean, green energy, thus minimizing the environmental pollution. Romania has an important potential for development of renewable energy, in the hydro, wind, solar, geothermal, and (...)


INFLUENCE OF THE CE ADDITION ON THE FUEL COMBUSTION PROCESS IN THE DIESEL ENGINE (Papers SGEM2018)

E. Kardasz, K. Pstrowska, P. Kardasz, V. Pohrebennyk, O. Mitryasova
Thursday 11 October 2018 by Libadmin2018
ABSTRACT Background. Reducing fuel consumption in the engine, while achieving assumed power is important for both reasons: the economic and the environmental. In this work series of studies of diesel fuel combustion in cogeneration system with the participation of 1:4000 vol. CeO2 concentrate: (...)
