“…Carbon monoxide values (8.5% on average) were also slightly lower than the values obtained in other studies (Parthasarathy and Sheeba, 2015). In the same line, the results obtained for CO 2 and CH 4 were also lower than those reported in different works studying the gasification of other lingo-cellulosic raw materials (Skoulou et al, 2008;Weerachanchai et al, 2009).…”

The plantation of fast growing trees in contaminated sites, in combination with the use of organic wastes, could partially solve a dual environmental problem: the disposal of these wastes and the improvement of soil quality in these degraded soils. This study evaluated the effects of two composts amendments on the quantity and quality of Paulownia fortunei biomass and on syngas production by biomass gasification, produced by plants growing on trace elements contaminated soils. Compost increased biomass production to values similar to those produced in non-contaminated soils, due to the improvement in plant nutritional status. Moreover, biomass quality for gasification was increased by compost addition. Trace element accumulation in the biomass was relatively low and not related to biomass production or the gas quality obtained through gasification. Thus, P. fortunei plantations could pose an opportunity to Preprint submitted to Elsevier 2 improve the economic balance of the revegetation of contaminated soils, given that other commercial uses such as food or fodder crop production is not recommended in these soils.

“…Alkali-based catalysts are expensive but have the capacity to enhance gasification rates (Weerachanchai, Horio, & Tangsathitkulchai, 2009). Nickel-based catalysts have been widely used owing to their high activity for steam reforming of hydrocarbons and tars at relatively low temperatures and because they lead to high percentages of H 2 and CO in the product gas mixtures.…”

“…Three types of measures can be taken as primary methods: the proper design of reactor [11], the right selection of operating: use and location of secondary air, equivalence ratio and biomass moisture [23]; steam and N 2 (pyrolysis) as gasifying agents [24]; co-gasification of high moisture woodchips and shredded rubber waste [25] and the use of proper bed additives/catalysts during gasification: silica sand, calcined limestone, combination of calcined limestone and calcined waste [24]; inert quartzite, olivine, dolomite, Niealumina [26]; silica sand, alumina, alumina impregnated with nickel [27].…”

This paper presents a modelling approach for simulating tars and particulate (dust) removal in a moving bed heat exchange filter (MBHEF) in order to satisfy gas requirements of end-use syngas applications: engines and turbines. The two-dimension, adiabatic, steady-state proposed model accounts for two-phase (gas and solid) and neglects conduction and mass diffusion. Tars condensation is modelled through representative tar class lumps: phenol (class 2), naphthalene (class 4), pyrene (class 5). The model also considers tar concentration influence on the tar dew point. The filtration model is taken from literature. A sensitivity analysis is performed varying the particle size and the superficial gas velocity. Maps of temperature and tars abatement efficiency are presented. The simulation results indicate the feasibility of the use a MBHEF as tars removal equipment benefiting its advantages against others gas-cleaning methods with acceptable pollutant removal efficiencies, ranging 88e94% for ranges studied. Results also point out low gas velocities (0.5-1 m/s) and high particle size (400e700 mm) for reducing operational costs in MBHEFs with compact size.
