Comparative studies on catalytic and non-catalytic co-gasification of rubber seed shell and high density polyethylene mixtures

Application of response surface methodology to investigate the effect of different variables on conversion of palm kernel shell in steam gasification using coal bottom ash

“…The desired temperatures were 650, 700 and 750°C based on the experimental design sheet. Equal steam to biomass ratio was used throughout the gasification based on the work reported by Chin et al [31] for conversion and kinetics study. Each of run was conducted for 30 min at a set temperature to ensure gasification.…”

“…Coal bottom ash was used as the catalyst. Catalyst used in biomass gasification is in the range of 0.1-1% of biomass weight as reported by Chin et al [31] and Khan et al [13]. Moreover, different parameters like particle size from 0.50 to 1 mm, temperature of 650-750°C, CaO to biomass ratio of 0.5-2 and percentage weight of coal bottom ash in biomass from 0.02 to 0.1 wt% were investigated to study their effect on conversion (X) and gasification rate (Rn).…”

Rescuing the Environment: Turning (Micro)plastics into Energy Through Gasification

“…Gasification is a thermochemical conversion scheme that converts carbonaceous materials into a synthetic gas (syngas), composed of carbon monoxide, hydrogen, methane, carbon dioxide and nitrogen (Balat et al 2009;Basu 2010). Sometimes using catalysts such as quartzite sand or Ni-based compounds promotes H 2 formation, while reducing methane (Ruoppolo et al 2012) or even endorses smaller activation energies (Chin et al 2014), enabling faster reactions and easier conversions. Catalysts like Ni-based, iron-based, calcined dolomites and magnesites, zeolites and olivine act in situ, advocating chemical reactions that alter syngas composition and heating value (Pinto et al 2015).…”

Influence of Glycidyl Methacrylate Grafting on the Mechanical, Water Absorption, and Thermal Properties of Recycled High-Density Polyethylene/Rubber Seed Shell Particle Composites

“…It has been reported that the plastic with the largest amount of consumption among polyolefins is high density polyethylene (HDPE), which constitutes one third of the world's plastic consumption (Chin et al 2014). With the over-exploitation of natural resources and energy as well as the globally pervasive consciousness of environmental protection, highvalued utilization of agricultural and forestry by-products to develop novel materials has become popular.…”
