Catalytic hydrothermal treatment of wood biomass was performed at 280 degrees C for 15 min in the presence of K2CO3 with different concentrations and biomass/water ratio (thermal). Oil products were extracted from both liquid and solid portion by different solvents and analyzed them individually. The biomass to water ratio has an important effect on product(More)
Accumulation of electronic waste has increased catastrophically and out of that various plastic resins constitute one of the leading thrown out materials in the electronic machinery. Enrichment medium, containing high impact polystyrene (HIPS) with decabromodiphenyl oxide and antimony trioxide as sole carbon source, was used to isolate microbial cultures.(More)
A method to recover both Br and Br-free plastic from brominated flame retardant high impact polystyrene (HIPS-Br) was proposed. HIPS-Br containing 15% Br was treated in autoclave at 280 degrees C using water or KOH solution of various amounts and concentrations. Hydrothermal treatment (30 ml water) leads to 90% debromination of 1g HIPS-Br but plastic is(More)
The increasing concerns over the depletion of fossil resources and its associated geo-political issues have driven the entire world to move toward sustainable forms of energy. Pretreatment is the first step in any biochemical conversion process for the production of valuable fuels/chemicals from lignocellulosic biomass to eliminate the lignin and produce(More)
In the present study, a new feedstock, Pongamia glabra deoiled cake (PGDC), is reported for pyrolysis. Experiments were conducted in a laboratory scale fixed-bed pyrolyzer at temperatures ranging from 350 to 600°C with varying heating rates of 10, 20, 40°C/min in nitrogen atmosphere. The highest liquid yield of 30.60% was observed at 500°C with heating rate(More)
The present study aims to explore the physico-chemical properties of Mesua ferrea L. (Iron wood tree) deoiled cake (MFDC) and decomposition parameters for thermochemical methods of conversion. The physico-chemical characteristics of MFDC were investigated by bomb calorimetry, TG/DTA (10, 20 and 40°C min(-1)), elemental analysis (CHN) and FTIR spectroscopy.(More)
The kinetics of thermal decomposition of rice straw was studied by thermogravimetry. Non-isothermal thermogravimetric data of rice straw decomposition in nitrogen atmosphere at six different heating rates of 5-40 °C/min was used for evaluating kinetics using several model free kinetic methods. The results showed that the decomposition process exhibited two(More)
