TheProduction of biofuel from biomass sources is believed to reduce the reliance of fossil fuel and its cost. This investigation was aimed to produce and characterize the bio-oil obtained from co-pyrolysis. Two different feed stocks were used for co-pyrolysis; one is Mahua seed (MS) and the other one is Polystyrene (PS). The effect in addition of plastic to biomass in pyrolysis process were investigated on the yield and quality of products. Experiments were conducted in a semi-batch pyrolysis reactor under various parameters of temperature, heating rate and blending ratio. The results indicated that a temperature of 525 °C, and blend ratio of 1:1is maximumwith a heating rate of 20 °C/min. The yield of bio-oil obtained from the co-pyrolysis was found to be approximately 71%, which was higher about 22% than that of yield obtained from pyrolysis of Mahua seed (MS) alone. Further the bio-oil was characterized using different spectroscopic and chromatographic analyses. The analysis of the results for characterization of bio-oil indicated that the synergetic effect increased the bio-oil yield and its quality.

The Impact

Relevance. One of the most important elements of the technology of cultivation of strawberries for increasing productivity and improving the quality of berries is the use of fertilizers that can regulate the growth, development, yield and quality of products.Methods. During 2016-2018, the impact of pre-planting application of complex mineral fertilizers on the yield and quality of strawberries in the Udmurt Republic was studied. The analysis of meteorological conditions during the growing season of the crop according to the research results is carried out.Results. The results of the use of complex fertilizers Azofoska, Perm-yagodnoye and Fusco-yagodnoye on garden strawberries when grown in the conditions of the Udmurt Republic are presented. It was found that the use of these fertilizers in comparison with the control (Azofoska) contributes to an increase in yield and has a positive effect on the quality of berries. The aftereffect of the studied fertilizers on the second and third year of fruiting of wild strawberries is noted. According to the results of research, the highest yield of berries of the garden strawberry was obtained in 2016 in the first year of fruiting when applying Chamfer-berry (1.33 kg/m2 ). The pre-planting application of the FaskoYagodnoye fertilizer provided a reliable increase in yield at all times of berry harvesting, and on average for three years by 0.13 kg/m2 with an NSR of 0.04 kg/m2 . The content of dry matter, water-soluble sugars and vitamin C in the berries corresponded to the characteristics of the Darenka variety and to a greater extent depended on the meteorological conditions of the growing season of strawberries.

Palm plantations in Indonesia began to grow rapidly since the early 80s. The area of ​​Indonesia's oil palm in 2013 was 10.4 million ha and increased 4.69% annually.  The production of palm midrib was about 22 midribs per tree per year with the weight of midrib meat ranging from 2.2 kg. The palm midrib is composed of cellulose, hemicellulose, and lignin, which can be used as liquid smoke. The purpose of this study was to analyze the effect of temperature and time of pyrolysis on the yield and quality of liquid smoke produced. The pyrolysis process of fractured palm was performed at 150 ºC, 200 ºC, and 250 ºC for 30 minutes, 60 minutes, 90 minutes. The results indicated that the yield of liquid smoke tends to decrease with increasing pyrolysis temperature, and tends to increase with increasing pyrolysis time in which the difficult condensed gas production increases with increasing temperature and time of pyrolysis. The highest yield of liquid smoke pyrolysis temperature of 150 OC with pyrolysis time 120 minutes that is equal to 43.47%. In this study, obtained the best results for a pH value of 3.1 is done at process temperatures of 250 ° C with processing time 60 minutes

The article shows in 4 links of field rotation on the light-gray medium loamy soil effects of winter rye and lupine on the yield and quality of potato crop, spring wheat and aftereffects on the yield of third crops - barley and fifth crops - potatoes. Narrow-leaved lupine on gray forest soils of the Chuvash Republic in comparison with winter rye is the best precursor for spring wheat and potatoes. This provides not only the reliable increase of productivity of these crops, but also improve the quality of products. The starch fees per unit area also rises. It should be noted an increase of gluten content in grain of spring wheat from 20.2 % to 29.2 %. An aftereffect of narrow-leaved lupine was manifested at the third level cultures-barley and fifth-potato.

Abstract The article is focused onthe energetical balance of a technical system for the conversion of crushed tyres by pyrolysis. Process temperatures were set in the range from 500 to 650°C. Mass input of the material was 30 kg per hour. The aim of the article is to answer the following questions as regards the individual products: Under which process conditions can the highest quality of the individual products related to energy be reached? How does the thermal efficiency of the system change in reaction to various conditions of the process? On the basis of the experimental measurements and calculations, apart from other things, it was discovered that the pyrolysis liquid reaches the highest energetic value, i.e. 42.7 MJ.kg-1, out of all the individual products of the pyrolysis process. Generated pyrolysis gas disposes of the highest lower calorific value 37.1 MJ.kg-1 and the pyrolysis coke disposes of the maximum 30.9 MJ kg-1. From the energetic balance, the thermal efficiency of the experimental unit under the stated operational modes ranging from about 52 % to 56 % has been estimated. Individual findings are elaborated on detail in the article.
