In this manuscript, the effect of various mixture proportions of a lignocellulosic material (palm shell) and waste tyres (a material not easily degraded in natural environmental conditions) subjected to a thermochemical process known as pyrolysis, on the distribution of the different fractions of the reaction products, was analyzed. The mixtures consisted of 20%-80%, 50%-50% and 80%-20% of palm shell and used tyre respectively, which were subjected to a co-pyrolysis, a simultaneous thermochemical decomposition of two biomass sources, and the resulting liquid and solid fractions were characterized. The experiments were carried out using a 0.5 mm-particle size under 500 °C for each pyrolysis run. The raw materials are characterized by proximate and elemental analysis, Fourier Transform Infrared Spectroscopy (FTIR) in addition to Thermogravimetric Analysis (TGA). Solid and liquid products were also characterized by FTIR, and their calorific value was also determined. The distribution of fractions was made by weight difference between the fractions and the mass fed. The pyrolysis run that obtained the best properties was the mixture of 80% waste tyres and 20% palm shells with a calorific value of 21,117 kJ/kg, obtaining three types of products with the following mass proportions: solid 23.5%, liquid 18.6% and gas 57.9%. It can be concluded that the solid product obtained has a great energy potential, superior than that of dry wood, which is 19,000 kJ/kg.

Sunflower Production

The aim of the work is to analyze technical and economic basis for the development of energy and biofuel production from sunflower growing by-products in Ukraine. The task of the work is to determine conditions that ensure the economic feasibility of such type projects in Ukraine. Results of assessment of the energy potential of sunflower production by-products in Ukraine are presented. Ukraine is a world leader in terms of sunflower gross harvest. Consequently the country has a large potential of by-products from sunflower growing and processing available for energy. Today, with the exception of sunflower husk, this type of biomass is practically not used for energy needs. Small amounts of sunflower growing by-products are mainly used by some agricultural producers and rural households to cover their own needs in heat. Taking into consideration the insufficiently described practice of harvesting this type of biomass and the undoubted prospects of its use for energy in Ukraine, it is necessary to conduct some field tests of harvesting technologies, at least on the basis of existing agricultural machinery, in particular, forage harvester and mulcher with a baler. Further research is needed on the technology of direct combustion of stalks and other by-products of sunflower growing, as well as the production of solid, liquid and gaseous biofuels from them.

The present study investigates the quality changes of wood bio-briquette fuel after the addition of spent coffee ground (SCG) into the initial feedstock materials (sawdust, shavings) in different mass ratios (1:1, 1:3). Analysis of SCGs fuel parameter proved great potential for energy generation by a process of direct combustion. Namely, level of calorific value (GCV = 21.58 MJ∙kg−1), of ash content (Ac = 1.49%) and elementary composition (C = 55.49%, H = 7.07%, N = 2.38%, O = 33.41%) supports such statement. A comparison with results of initial feedstock materials exhibited better results of SCG in case of its calorific value and elementary composition. Bulk density ρ (kg·m−3) and mechanical durability DU (%) of bio-briquette samples from initial feedstock materials were following for sawdust: ρ = 1026.39 kg·m−3, DU = 98.44% and shavings: ρ = 1036.53 kg·m−3, DU = 96.70%. The level of such mechanical quality indicators changed after the addition of SCG. Specifically, SCG+sawdust mixtures achieved ρ = 1077.49 kg·m−3 and DU = 90.09%, while SCG + shavings mixtures achieved ρ = 899.44 kg·m−3 and DU = 46.50%. The addition of SCG increased wood bio-briquettes energy potential but decreased its mechanical quality. Consequently, the addition of SCG in wood bio-briquette has advantages, but its mass ratio plays an important key role.
