Pyrolysis of jute stick for bio-oil production has been investigated in a continuous feeding fluidized bed reactor at different temperatures ranging from 300 degrees C to 600 degrees C. At 500 degrees C, the yields of bio-oil, char and non-condensable gas were 66.70 wt%, 22.60 wt% and 10.70 wt%, res...

Activated carbons have been prepared from jute sticks by chemical activation using ZnCl(2) and physical activation using steam for the removal of Brilliant Green dye from aqueous solution. The activated carbons and charcoal prepared from jute sticks were characterized by evaluating the surface chemi...

The char derived from pyrolysis of jute stick for bio-oil production was activated by physical method using steam. The yield of activated carbon was varied with the variation of activation temperature and steam flow rate. About 50% activation burn-off of char at 750°C with 75 mg/min steam flow rate ...

Charcoal was prepared from coconut shell and activated at three temperatures 300, 350 and 400°C in constant flow of air or nitrogen. Adsorption of oxalic acid and maleic acid from their aqueous solution on charcoal was studied. Oxalic acid gave Langmuir type of adsorption isotherm indicating monolay...

High specific surface area activated carbon has been produced from the chemical activation of jute stick using H 3 PO 4 as an activating agent at different temperatures in the range 673–973 K. The BET surface area of the activated carbon was measured by nitrogen adsorption methods. The maximum speci...

Arsenic removal from water in the form of As(ΙΙΙ) and As(IV) was investigated using activated carbon obtained from jute stick using H 3 PO 4 . Arsenic contaminated water was treated in two ways: (1) batch feeding system and (2) continuous flow system through a column filter. Removal of arsenic in co...
