Cation Nature

Bio-oil (pyrolysis oil) is an essential feedstock for the production of renewable fossil-free fuels and valuable chemicals. Enhancement of the pyrolysis oil yield and its quality are significant challenges for an efficient and sustainable biorefinery. Here, we report the microwave (MW)-assisted noncatalytic pyrolysis of cellulose, as a green and controllable alternative to conventional heating, in the presence of eco-friendly Li-, Na-, K-, Mg-, Ca- and Ba-bentonites. The detailed analysis of the MV heating traces demonstrates that the bentonite MW activity significantly depends on the presence of internal water. The intensity of this interaction is controlled by the cation nature reduced in the order: Li+ > Na+ > K+ and Mg2+ > Ca2+ > Ba2+. A unique experimental design for the MW-assisted pyrolysis of cellulose in the presence of Li-doped clays helps to increase the bio-oil yield to 37.8% with high selectivity towards the commercially useful levoglucosan (purity: 39.36%). The combination of an alternative green heating method and environmentally friendly bentonites can be used many times without recycling. We believe that the improved yields of bio-oil are due to: (i) high MW activity of bentonites, which conventionally increases the heating rates of cellulose; and (ii) production of water by hydrophilic clay minerals, favouring depolymerisation of cellulose.

As a part of improving the quality of the distillate (distilling temperature 120–350 °C) recovered from waste plastic pyrolysis oil (WPPO) by simple distillation, the enrichment of paraffin components present in the distillate was compared by the equilibrium extraction of dimethylformamide (DMF) and dimethylsulfoxide (DMSO). Regardless of the solvent used, the concentration increase rate of the paraffin component in the raffinate relative to the raw material was reduced by increasing the mass fraction of water in the solvent in an initial state. On the other hand, it increased by increasing the mass ratio of the solvent to the raw material in an initial state. The enrichment performance of paraffin component in raffinate recovered by DMF was higher than that by DMSO under the same experimental conditions. Furthermore, the two solvents were compared by adding color and the waxing phenomena of recovered raffinate to assess the enrichment performance of paraffin components.

Descriptive Approach

ENGLISHPati Regency has a great potential production of consuming salt but there is an indication that the existing production of consuming salt is not optimum. The objectives of the research are: 1) to analyze the potential production of consuming salt in the study area; and 2) to analyze the existing production of consuming salt in the study area. The research uses descriptive approach. The data consist of primary data and secondary ones. Data collecting uses techniques of interview, field-events and document observation. The analysis uses descriptive one. There are three main findings in the research. Firstly, the potential production of consuming salt in Pati Regency is nearly 209,202 tons yearly but the existing production of consuming salt is 73,380 tons yearly, which is equal to 35.076% from the provided local potential production of consuming salt. Secondly, normatively local community in Pati Regency has consumption to salt 6,674 ton yearly, and the ekspor potential of salt is 202,527 ton yearly but the approximately annual salt ekspor is 66,706 ton because the realized production is not optimum. Thirdly, the product quality of consuming salt in the study area is under standard in general because of under standard raw materials and under standard equipments for production. INDONESIAKabupaten Pati memiliki potensi produksi garam sangat besar tetapi ada indikasi realisasi produksi garam konsumsi belum optimal. Penelitian ini bertujuan untuk: 1) Menganalisa potensi produksi garam konsumsi di area studi; dan 2) Menganalisa eksistensi produksi garam konsumsi di area studi. Penelitian ini menggunakan pendekatan deskriptif. Data penelitian meliputi data primer dan data sekunder. Pengumpulan data menggunakan teknik wawancara, observasi lokasi (field-events) dan observasi dokumen. Analisis data menggunakan analisis deskriptif. Penelitian ini memiliki 3 temuan utama. Pertama, potensi produksi garam konsumsi di Kabupaten Pati sebanyak 209.202 ton per tahun tetapi realisasi produksi hanya sebesar 73.380 ton per tahun (35,076%) dari total potensi yang tersedia. Kedua, secara normatif konsumsi masyarakat domestik terhadap garam konsumsi di Kabupaten Pati sebesar 6.674 ton/tahun, dan daerah ini memiliki potensi ekspor garam konsumsi sebanyak 202.527 ton per tahun tetapi realisasi ekspor garam konsumsi hanya sebesar 66.706 ton per tahun karena realisasi produksi yang tidak optimal. Ketiga, kualitas produksi garam konsumsi di area studi umumnya di bawah standar dikarenakan faktor bahan baku yang kurang baik dan proses produksi yang tidak memiliki sarana/prasarana yang memadai.

Abstract The soil production attributes of historical agrarian terraced fields were examined in the Budina cadastral area of the Ostrozky Mountains. This landscape represents a unique sub-mountainous Carpathian landscape with farms that use a historically preserved triple-field agricultural system. We determined the geo-spatial parameters of different types of land cover and terraces using geographic information systems. The soil depth was measured in the field, and the skeleton content was determined in the laboratory. We compared data regarding the potential production capabilities of the soil with data from the national classification of agricultural soils. Our results indicated that the soil productivity attributes improved because the naturally less fertile cambisols were positively affected by terracing and long-term cultivation. We recommend the preservation of traditional agricultural activities in historical terraced fields because these terraces represent valuable features that improve the quality of the landscape.

Abstract Huanglongbing (HLB) is considered one of the main citrus diseases; it spreads quickly through orchards, reducing the production and quality of the fruit of affected plants, and causes significant economic losses. In this context, the aim of this study was to estimate the incidence and economic impact of the losses generated by HLB in the micro-region of Paranavaí, in the state of Paraná, Brazil. We used data from the Paraná Agribusiness Defense Agency, which conducts surveys of host plants of the causal agent of HLB. The production sacrificed by HLB was estimated considering the following scenarios: (i) losses occurring from January 2011 to June 2013; and (ii) losses related to the potential production of the citrus plant over its useful life. Although the annual incidence of HLB in the Paranavaí region is currently below 2.5%, there was a 6-fold increase in the incidence of the disease, from 0.16% to 0.96%, in the period considered. Orchards that had lesser than 10,000 plants showed a higher incidence of the disease. The losses produced by HLB generated estimated economic impacts of US$11.8 million and US$39.2 million for the first and second scenarios, respectively. These results highlight the importance of the prevention and management of this disease.
