“…No sistema de limpeza de gás, durante o resfriamento rápido do syngas e o não aproveitamento do calor exaurido por este processo, as perdas podem significar 7% na eficiência líquida, por exemplo. Um aumento de temperatura na ordem de 50 •C pode causar uma redução de 0,4% na eficiência líquida do sistema (HAN et al, 2018).…”

projeto de extensão com decorrências no contexto contemporâneo de consumo. Para isso, foi realizada uma análise por meio das confluências entre a literatura e o arsenal documental do projeto para sua caracterização extensionistas. Observou-se, a partir da pesquisa, que o Clube de Trocas tem possibilitado a ressignificação do consumo e a mitigação de suas consequências, pautando assim a construção de uma nova epistemologia benéfica e solidária. Além disso, o mesmo tem se apresentado como um espaço potencial para a formação coletiva que propicia a experimentação e a vivência de outra dinâmica de consumo, direta, critica e socializadora.

“…Particulates may cause plugging and abrasion of downstream piping and equipment during combustion in gas turbines or internal engines. , Desulfurization prior to combustion of combustible gas is also critical as H 2 S therein is converted to SO x (during combustion), which may also contribute to the formation of secondary inorganic aerosol gases and fine particulates . Ceramic filters (CFs) with high thermal resistance can be used in the removal of particulates from off-gases at T > 673 K. Rigid ceramic filters have also been practical in combustion and gasification of fossil fuels and biomass for environmentally clean power generation . Direct applications of high-temperature particulate controls with CFs are expected to be beneficial to the advanced fuel processing technologies …”

High-Temperature Syngas Desulfurization and Particulate Filtration by ZnO/Ceramic Filters

Combustible gas (e.g., gasification syngas) cleaning at high temperatures can obtain further gains in energy efficiency for power generation and importantly leads to a simplified process and lower cost as a commercially viable source of clean energy. Thus, a feasibility study for high-temperature desulfurization (HTDS) and additional high-temperature particulate filtration (HTPF) of a raw syngas using ZnO sorbent-dispersed Raney CuO (ZnO/R-CuO) and ceramic filter (ZnO/CF) has been carried out. By synchrotron X-ray absorption near-edge structure (XANES) spectroscopy, mainly Zn(II) and Cu(II) are found in the ZnO/R-CuO sorbents. Both ZnO and R-CuO in the sorbents are involved in HTDS (1% H2S) at 873 K to form ZnS, Cu2S, and a small amount of CuS and reach relatively high HTDS efficiencies (82–90%). In addition, regeneration of the sulfurized sorbent by oxidation with O2 at 873 K (HTRG) for 1 h can restore ZnO and CuO for continuous and repetitive HTDS-HTRG cycles. To facilitate the HTDS engineering applications by the ZnO/R-CuO sorbents, their reaction rate constant (8.35 × 104 cm3/g/min) and activation energy (114.8 kJ/mol) at 873 K have also been determined. Furthermore, the ZnO/CF sorbent/filter can perform HTDS and additional HTPF at 873 K with very high particulate removal efficiencies (>98%). This demonstrates the feasibility for hot-syngas cleaning with a much better energy efficiency and lesser cost for cleaner power generation.

“…Fossil fuel is still the most important energy resource at present. [1,2] The clean and effective utilization of coal is essential to the low-carbon society, especially countries rich in coal resources. [3,4] Recently, the entrained flow gasification (EFG) technology has been developing rapidly for the syngas production in the modern coal chemical industry.…”

Radiant syngas cooler (RSC) is an important piece of equipment for heat recovery and steam generation in the gasification plant. In this work, the industrial RSC model of an opposed multi-burner coal-water-slurry gasification device is established, and the heat recovery performance of RSC is studied by numerical simulation method. The simulation result of the total heat transfer rate is compared with the industrial operation data. The effect of different operating parameters on RSC is further studied, including the operating load, inlet syngas temperature, and ash deposition thickness. The results show that there is a spindle-shaped high-temperature zone on the circumferential membrane wall surface with a distance of 6.5 m from the top under the basic operating conditions. There is also an obvious high-temperature zone in the mid-upper section
