Gasification is an advanced thermochemical process that converts carbonaceous feedstock into syngas, a mixture of hydrogen, carbon monoxide, and other gases. However, the presence tar in which composed higher molecular weight aromatic hydrocarbons, poses significant challenges for downstream utilization syngas. This Review offers comprehensive overview from gasification, encompassing gasifier chemistry configuration notably impact formation during gasification. It explores concentration composition syngas purity required applications. Various removal methods are discussed, including mechanical, chemical/catalytic, plasma technologies. The provides insights strengths, limitations, associated with each method. also highlights importance integrating multiple techniques to enhance efficiency quality. selection appropriate strategy depends on factors such as composition, operating design factors, economic considerations, extent at application. Future research should focus developing cleaning strategies consume less energy cause smaller environmental impact.

Pyrolysis is a promising disposal method for municipal solid waste (MSW) due to the high-value utilization of organic components MSW. Traditional indirect heating has low heat transfer efficiency and requires an increase in exchange area. In this study, refined numerical simulation model pyrolysis four typical MSW with high-temperature flue gas was established study influence on reaction characteristics The temperature distribution particle size change different were obtained, effects velocity process analyzed. It found that difference along bed height direction about 1.36–1.81 K/mm, energy 55–61%. When uniformly mixed, rates each component similar during process. As increased, amount consumption decreased increased. increased decreased. research results are great significance promotion application technology gas.

The combustion behavior and thermal performance of industrial-scale borax pentahydrate (Na2B4O7·5H2O) melting furnaces remain underexplored despite their critical role in boric oxide (B2O3) production, a key input for high-performance manufacturing. This study addressed this gap by employing three-dimensional computational fluid dynamics (CFD) simulations to model two operational natural gas-fired with distinct burner configurations (four-burner six-burner systems). analysis focused on optimizing placement, specifically, the axial distance inclination angle, enhance uniformity reduce refractory wall damage caused aggressive high-temperature borate corrosion. A comprehensive parametric twelve revealed that tilting burners at 5–10° significantly improved temperature while reducing peak temperatures mitigating localized hot spots. optimal design, incorporating 10° angle staggered arrangement (Case 11), attained melt pool 1831.3 K charging average 1812.0 K. These values represent essential benchmarks maximizing furnace efficiency stability. modified designs four- systems led distributions notable reduction maximum temperatures, directly contributing longer maintenance intervals durability. findings confirm minor geometrical angular adjustments placement can yield significant gains. validated CFD approach proposed design modifications offer scalable, low-cost strategy improving lifespan processing facilities.
