In the first step, the thermal behavior of biomass was determined by analyzing the mass loss during non-catalytic gasification with the use of TGA. The results of thermogravimetric analysis were used to assess the course of the biomass heating process in the atmosphere of CO 2 and to distinguish the individual phases of this process. Then, the thermovolumetric measurements of MG gasification were taken with the use of Ni/Al 2 O 3-SiO 2 and Ni/Al 2 O 3-SiO 2 with K 2 O promoter as catalysts. The obtained results allowed determining the process rate as well as composition of the resulting gas and yields of main gaseous products (CH 4 , CO, H 2). The use of Ni/Al 2 O 3-SiO 2 as catalyst resulted in the highest conversion rate of MG gasification into gaseous products with considerably increased contents of H 2 and CO. The second analyzed catalyst-Ni/Al 2 O 3-SiO 2 with K 2 O promoter-did not catalyze the gasification process. However, the use of both tested catalysts had a positive effect on reducing the methane content in the resulting gas. One can also suppose that it promotes the decomposition of the tar formed in the process.

TGA tests were performed in high purity carbon dioxide (99 998%) with a flow rate 200 ml/min and 100 mg of sample, milled and sieved to a particle size below 250 mm. Moreover, yields of gasification products such as hydrogen (H 2), carbon monoxide (CO) and methane (CH 4) were determined based on the thermovolumetric measurements of catalytic (Ni/Al 2 O 3-SiO 2 and Ni/Al 2 O 3-SiO 2 with K 2 O promoter catalysts) and non-catalytic gasification of the Rosa multiflora biomass. Additionally, carbon conversion degrees are presented. Calculations were made of the kinetic parameters of carbon monoxide and hydrogen formation reaction in the catalytic and non-catalytic CO 2 gasification processes. A high temperature of 950°C along with Ni/Al 2 O 3-SiO 2 and Ni/ Al 2 O 3-SiO 2 with K 2 O promoter catalysts resulted in a higher conversion of Rosa mutiflora biomass into gaseous yield production with greatly increasing of H 2 and CO contents. Consequently, H 2 and CO are the key factors to produce renewable energy and bio-gases (synthesis gas). The parameters obtained during the experimental examinations enable a tentative assessment of plant biomasses for the process of large-scale gasification in industrial sectors.

However, its transition to cleaner cooking fuels is still low where the household’s fuels preferences play an important role in the process. To examine the factors that influence the household’s cooking fuel choice in Northern Sudan, a multinomial logit model (MNL) was used to analyze data collected from Kassala state in two selected districts, New Halfa and Nahr Atabara. The findings show that the most utilized fuels are still firewood and charcoal, which are used by 63.4% of all respondents. The results also revealed that socioeconomic factors have an impact on household fuel choice, where one additional unit of credit access may boost the possibility of choosing LPG by 22.7%. Furthermore, one additional level of education would reduce 5.4% of charcoal users while simultaneously raising 10% of current liquefied petroleum gas (LPG) users. Therefore, the study suggests initiating mobil...

Here we review complementary eco-innovations for sustainable development in different regions. One of the newer biotechnologies is laser photostimulation of different species of plants and microorganisms to increase their adaptability to xenobiotics in soil, air, and water. Empirically selected algorithms of laser irradiation significantly increase biodegradation of hydrocarbons, phytoremediation of trace metals by willow Salix sp., elephant grass Miscanthus x giganteus, Virginian mallow Sida hermaphrodita, and to increase tolerance of different species of plants to petrochemical pollutants and efficiency of reclamation of contaminated areas and tolerance to salinity of soil and suboptimal temperatures as well as water deficiency. This biotechnology is also useful for biomass enhancement and bio-energy production under suboptimal conditions for more efficient vegetative multiplication of some vegetables and development of sustainable agriculture, forestry, protection of the landscape, and biodiversity. Integration of transdisciplinary cooperation and application of complementary biotechnologies and innovative methods of environmental pollutant bioremediation (such as wastewater treatment) and reclamation, supported by the implementation of a neural network, can optimize bioprocesses that are useful for a better quality of life, globally. Long-term research-developing studies are supplemented by problem-solving training and case studies in different regions (including ecotourism, recreation, and promotion of ecological culture), long distance education and life-long education for the common action of experts and knowledge-based society, promoting sustainable development that is based on integrated biological sciences and sustainable models of consumption.

There is certain isolation of networks and power lines from generation facilities; attention is lost to such an important problem as the reliability and safety of power supply. In this situation, the load on the power elements of the electric network increases, there is a need to create appropriate reserves of generating capacities, to increase the throughput of electric networks. All this involves increasing the role of system operators and improving supervisory control systems. The strategic goal of this study was to analyze the development of the electric power complex by the creation of smart grid systems as a platform for market, managerial and technological innovations that provide a transiti...

In this study, MSW and coal samples were chosen as principal components. The mixture of these products was pyrolyzed in a horizontal tube furnace at 800 • C with a heating rate of 20 • C/min. The tar derived from the pyrolysis of this mixture was further studied. Gas chromatography-mass spectrometry (GC-MS) coupled with a trace GC and a nuclear magnetic resonance (NMR) spectrometer was applied to investigate the tar composition and characterization along with their molecular chemical structures. 1 H and 13 C NMR spectra indicated that the functional groups of the tar derived from the mixture of MSW and coal were dominant at the resonances of 0.9-1.8 ppm, 1.5-2.6 ppm and 3.8-4.1 ppm for 1 H, 10-40 ppm and 60-80 ppm for 13 C. The results from GC-MS showed that the tar derived from the mixture of MSW and coal contained about 20 major chemical compounds such as benzene, methyl isobutyl, toluene, xylene, phenol, cresol, naphthalene and others. c

Technological innovations and measures to lessen environmental impacts make small-scale hydropower stations inexpensive and justified energy sources that provide renewable energy on an independent basis and help not only to protect the environment but also to weaken human dependence on fossil fuels. This study is devoted to finding solutions based on renewable energy technologies and innovations in Uzbekistan. This article is devoted to the development of a water wheel experimental model for the micro-hydroelectric power station. Experimental studies were carried out on the basis of this model and obtained results were used in the preliminary calculations. The results from the calculations showed that the installation can generate 7-11 kWh of electricity per hour, about 168-264 kWh of electricity per day and 61 to 96 MWh of electricity per year.
