In the production of rice a large amount of solid residue is produced, for which alternative utilizations are scarce or are not commonly applied in industry. Rice straw (RS) is a waste product of rice harvest that is generated in equal or greater quantities than the rice itself. RS is frequently burned in open air, which makes it a significant source of pollution. In the search for possible uses of RS, it should be noted that its ash (RSA) is particularly rich in silica, alkaline and alkaline earth metals and may be used as a source of alkalis and silica for the production of triaxial ceramics. The present research work proposes the production of a ceramic raw material from RS for its use in the fabrication of ceramic materials for the construction industry. Based on the chemical and mineralogical composition of RSA created under different thermal conditions, the most suitable RSA for this purpose was that obtained from treating RS at a temperature of 800 °C for a time of 2 h. The resulting RSA presented high contents of SiO 2 (79.62%), alkaline oxides (K 2 O) (10.53%) and alkaline earth oxides (CaO) (2.80%). It is concluded that RSA is a new alternative ceramic raw material that can be used as a replacement for the fluxing (mainly feldspar) and inert (quartz) materials that are used in the production of triaxial ceramics.

“…However, no trace of sulfur and chlorine was detected in both feedstocks. The elemental composition of pine sawdust showed similar characteristics when compared with the results in other articles [26,27]. In the case of TSRFR, it shows an agreement with element composition of RDF reported by Kathirvale et al [28] and Cozzani et al [29].…”

Co-Gasification of Treated Solid Recovered Fuel Residue by Using Minerals Bed and Biomass Waste Blends

Solid recovered fuel (SRF) residue, which is leftovers from the SRF manufacturing process, usually is discarded in landfill because of its low heating value and high ash and moisture content. However, it could be used as a fuel after mechanical and biological treatment. Gasification experiments were conducted on treated SRF residue (TSRFR) to assess the viability of syngas production. Efforts were also made to improve the gasification performance by adding low-cost natural minerals such as dolomite and lime as bed material, and by blending with biomass waste. In the case of additive mineral tests, dolomite showed better performance compared to lime, and in the case of biomass blends, a 25 wt% pine sawdust blend with TSRFR showed the best performance. Finally, as an appropriate condition, a combined experiment was conducted at an equivalence ratio (ER) of 0.2 using a 25 wt% pine sawdust blend with TSRFR as a feedstock and dolomite as the bed material. The highest dry gas yield (1.81 Nm 3 /kg), with the highest amount of syngas (56.72 vol%) and highest lower heating value (9.55 MJ/Nm 3 ) was obtained in this condition. Furthermore, the highest cold gas efficiency (48.64%) and carbon conversion rate (98.87%), and the lowest residue yield (11.56%), tar (0.95 g/Nm 3 ), and gas pollutants content was observed.Energies 2020, 13, 2081 2 of 16 48,934 tons of MSW per day [8]. Usually, this MSW carries an incredible amount of materials like plastic, paper, wood, metals, and glass which can be recycled easily and effectively by doing energy recovery [9].Gasification of MSW is a productive way of generating heat and power. In addition, it is a propitious route to produce fruitful end products using various synthesis routes [10]. In the past decades, gasification of biomass and waste has been comprehensively studied by many researchers [11][12][13], whereas, in the present day, gasification of solid recovered fuel (SRF), an alternative fuel produced from the combustibles in MSW, is one of the key topics in waste gasification [1,[14][15][16].In South Korea, during the SRF manufacturing process, there is a significant amount of residue generated which approaches 40 wt% of input waste, and the disposal cost occupies 20% of the annual operating cost in a few manufacturing facilities [17]. The SRF residue produced as leftovers during the SRF manufacturing process is usually discarded in landfill because of its high ash content (>20 wt%) and high moisture content (>10 wt%) but low energy content (<3500 kcal/kg). However, the South Korean government has set a goal to reach 3% landfill for overall waste and zero landfill for recyclable waste by the year 2020 [8]. In addition, by the year 2050, the South Korean government aimed to expand the share of renewable and new energy to 20% [18]. Thus, to support the South Korean government's vision, in this study, an effort was made to recover energy from SRF residue via the gasification process. However, before applying the gasification process, to improve the quality of SRF residue it was tr...

Lignocellulosic biomass is a renewable feedstock that has the potential to replace the diminishing fossil fuels. Herein, we reported the simultaneous conversion of cellulose, hemicellulose and lignin from raw biomass into gasoline alkanes (hexanes and pentanes) and monophenols and related hydrocarbons over layered LiTaMoO 6 and Ru/C in aqueous phosphoric acid medium. Specifically, gasoline alkanes were directly yielded from the carbohydrate components, based on hemicellulose and cellulose, and the total yield could be up to 82.4%. Notably, the lignin fraction could also be transformed into monophenols, related alcohols and hydrocarbons by the one-pot reaction. It suggested that the hydrocracking of monophenol fraction could be performed in this catalytic system. The total yield of volatile products was 53% based on the lignin fraction. In this paper, the influences of phosphoric acid concentration, substrate ash and the amino acids derived from the biogenic impurities were investigated and different raw biomass substrates were tested. Furthermore, the catalysts could be reused for several runs to convert raw biomass without pretreatment.
