“…The equivalence ratio (ER) is the prime considered parameter as it greatly affects the outcome of the gasification processes. Some researchers have taken it in the range of (0.08-0.8) [48], while some varied it is only a small range (0.12-0.4) [12], [16]. For the present study, the ER is changes from 0.2 to 0.4.…”

Present study concerns with the production of H2 rich product gas by thermochemical energy conversion having biomass gasification as a route for the four biomasses i.e., Kasai Saw Dust, Lemon Grass, Wheat Straw and Pigeon Pea Seed Coat. The biomasses are from the family of woody biomass, grasses, agricultural waste and food process industry wastes. Waste engine oil as an additive is used, which also acts as a binder. Air gasification and Air-steam gasification is applied and compared for product gas composition, hydrogen yield and other performance parameters like lower heating value, energy yield. Product gas constituents, hydrogen production is examined with different steam to biomass ratio (S/B ratio) and equivalence ratio. The equivalence ratio varies from 0.20-0.40 and the steam to biomass ratio varies between 0-4. The waster engine oil is mixed with the biomasses with different percentage of 5 and 10 wt%. For enhancement of feedstock quality palletization process is applied. The H2 yield is greatly affected by the equivalence ratio. Results show maximum H2 production and higher calorific value of product gas at an air to fuel of 0.26 for all the biomass pallets. Also, the S/B ratio observed as important aspect for hydrogen enrichment. Hydrogen yield is maximum at 2.4 steam to biomass ratio. This study considers the rarely studied Indian biomasses with waste engine oil as an additive for hydrogen-rich product gas production and will be beneficial for small scale hydrogen-rich syngas production considering the central Indian region originated biomasses. Statement of Novelty (SON):Research work belongs to eco-friendly use of rarely studied Indian biomass pallets. Equivalence air to fuel ratio (E/R ratio), steam to biomass ratio (S/B ratio) and waste engine oil as additive have been considered to upgrade H2 content and Calorific Value (CV) of the product gas. Novelty of work include use of waste engine oil as additive to make biomass pallets.

“…Lv et al, 2007 applied the air and O2/H2O(vapour) as gasifying agent in downdraft gasifier and observed that steam gasification is more favourable for H2 rich gas production [15]. Adefeso et al, 2015 integrated the H2 rich gas with fuel cell based structure [16]. S. Valizadeh et al, 2021 applied steam and air gasification [17].…”

The main reason that drives many developing countries to pursue waste-to-energy (WtE) technologies is that it produces energy while eliminating build-up of large quantities of wastes, at a time, when oil and gas reserves are declining. The rate of generation of municipal solid wastes (MSW) in any given country depends on many factors including economy, population, and modernization of industry and infrastructure developments. The United Arab Emirates (UAE) is a federation of seven emirates that has grown to be one of the Middle East's most important economic centers. UAE has also become one of the highest waste producing countries due to fast development and growth; thus, UAE pursue modern technologies to covert generated wastes into energy. In this communication, the status of ongoing waste to energy projects and WtE plants that are currently under design and construction in UAE are discussed. The need for development of WtE technologies is presented based on the literature, reports, economics and the environmental regulations.

“…12−16 Refuse-derived fuel (RDF) produced from raw MSW via segregation, crushing, mixing, and compression into pellets is homogeneous, exhibits a high LHV and low levels of moisture and ash, and is easy to handle and store. 17 Therefore, RDF gasification is of major interest. Hwang et al compared the pyrolysis and steam gasification performance of woody waste, RDF, and refuse paper and plastic fuel (RPF); temperature had a large impact on gasification, steam gasification of RDF at 900 °C was impressive, and the gas yield was increased by tar reforming.…”

Oxygen-enriched gasification of single-feed refuse-derived fuel (RDF) and dry sewage sludge (DSS) in a laboratory-scale fluidized bed was investigated. The optimal temperature, equivalence ratio (ER), and oxygen concentration of RDF and DSS gasification were 800 °C, 0.292, 50% and 750 °C, 0.321, 44.7%, respectively. The low heating values (LHVs) and cold gas efficiency (η values) of syngases from RDF and DSS were 6.79 MJ/Nm 3 , 53.0% and 6.51 MJ/Nm 3 , 49.2%, respectively, under optimal conditions. To improve the quality of DSS syngas, the effect of the RDF mixing ratio on RDF and DSS cogasification was investigated at 800 °C, with an ER of 0.321 and an OC of 44.7%. The gas yield increased continuously with increased RDF mixing ratio, and η rose to 55.0% with relatively high LHV of producer gas at a 25% mixing ratio of RDF.
