Power production waste

High efficiency power production from biomass and waste

Two-stage gasification allows power production from biomass and waste with high efficiency. The process involves pyrolysis at about 550°C followed by heating of the pyrolysis gas to about 1300°C in order to crack hydrocarbons and obtain syngas, a mixture of H2, CO, H2O and CO2. The second stage produces soot as unwanted by-product. Experimental results are reported on the suppression of soot fo...

Combustion of Municipal Solid Waste for Power Production

Waste Heat to Power Systems

Waste heat to power (WHP) is the process of capturing heat discarded by an existing industrial process and using that heat to generate power (see Figure 1). Energyintensive industrial processes—such as those occurring at refineries, steel mills, glass furnaces, and cement kilns—all release hot exhaust gases and waste streams that can be harnessed with wellestablished technologies to generate el...

Polyhydroxyalkanoates production from waste biomass

Polyhydroxyalkanoates (PHAs) is a group of biopolymers that are extensively researched for such purpose due to the biocompatibility with mammal tissue and similar properties with conventional plastic. However, commercialization of PHA is impended by its high total production cost, which half of it are from the cost of pure carbon source feedstock. Thus, cheap and sustainable feedstocks are pref...

Utilization of Alumina Waste and Silica Waste for Geopolymer Production

This research studies the utilization of alumina waste and silica waste for geopolymer production. Alumina waste was obtained from aluminium thermal metallurgy industry, silica waste was obtained from silicone recycle industry in Thailand. This present study aimed at investigating the basic physical and chemical properties of waste materials and also the optimal proportion in geopolymer product...
