Chemical Composition Of Palm Oil Fuel Ash

There are two types of palm ash waste which are palm oil fuel ash pofa and boiler ash.

Chemical composition of palm oil fuel ash. Laboratory analysis conducted centered on properties of sundried raw pofa passing through 150μ 75μ 38μ test sieves and of the fine ground. Unburned carbon which is a major part of unburned residue in gpofa was removed by heat treatment at 500 c. Palm oil fuel ash is the product of burning palm oil husk and palm kernel shell in the palm oil mill. Some of the ash forming constituents occur naturally in crude oil.

The ash content of a fuel is a measure of the amount of inorganic noncombustible material it contains. Pofa is rich in sio 2 therefore is a good pozzolanic material. The ground palm oil fuel ash gpofa and ground river sand grs were used to replace the portland cement by gpofa or grs at 10 20 30 and 40 by weight of cementitious materials whereas the water to binder ratio w b was 0 35 for the mixes of cement pastes. 5 recently pofa has been demonstrated as a nourishing fertilizer for.

Pofa reduces drying shrinkage as well as workability of concrete. Pofa obtained from oil palm india limited kottayam in kerala was used in the investigation. Others are present as a result of refining or contamination during storage or distribution. This research investigates the influence of calcination temperatures of palm oil fuel ash pofa on the properties of the raw precursor and its hardened binder after alkali activation.

Ultrafine and nano pofa increase the compressive strength of concrete. The raw pofa obtained from palm oil mill is treated at 500 c 600 c and 700 c for approximately 6 h. 2009 indonesia was the largest producer of palm oil 16 surpassing malaysia in 2006 producing more than 20 9 million tones. The specific gravity of palm oil fuel ash was 1 65 the chemical composition of pofa was tested at department of mining geology thiruvananthapuram.

Ash ranges from 0 1 0 2. This paper presents the physico chemical properties of palm oil fuel ash pofa a biomass residue while justifying its use as composite sorbent when admixed with kaolin clay for the purpose of designing composite sanitary landfill liner. The palm oil fuel ash pofa was ground in a ball mill to produce ground pofa gpofa. Approximately 10 million tons per year in malaysia 4 and 104 tons per year in thailand.

Meanwhile the chemical composition of boiler ash detected the existence of minerals and metal such as al mg cr and fe 19. Palm oil is the second most important crop after rubber as source of income and for export. 3 usually this biomass is used as a boiler fuel to produce heat or electricity producing a large amount of palm oil fuel ash pofa waste. In 2008 malaysia produced 17 7 million tons of palm oil on 4 500 000 hectares of.
