The raw material oil for needle coke has a density of 1.00-1.40 g/cm3 at 15°C, a kinematic viscosity of 17 mm2/s or less at 100°C, and an asphaltene content of 8.5 mass% or less.

To provide a method for adjusting the water content of a raw material capable of adjusting the water content of the raw material to an appropriate water content according to the particle size, a method for producing coke, and an apparatus for adjusting the water content of the raw material.SOLUTION: The method for adjusting the moisture content of the raw material is a method for adjusting the moisture content of the raw material executed by a moisture adjusting device (14) in a moisture conditioning facility including a conveyance line for conveying the raw material pulverized by a pulverizer (2), a measurement device for measuring the particle size of the conveyed raw material, and a moisture conditioner (4) for conditioning the moisture of the raw material whose particle size is measured, and includes acquiring the particle size measured by the measurement device, and changing the target value of the moisture content of the raw material of the moisture conditioner based on the measured particle size.SELECTED DRAWING: Figure 1

The present invention relates to a charging port lid structure of a coke oven that prevents damage caused by high heat generated during the carbonization process of raw coal. The above lead structure may be characterized as a lead structure for opening and closing a charging port formed at the top of a carbonization chamber, comprising: a lead body having a hollow shape and a hole formed therein; and a plurality of reinforcing members installed along the circumference of the outer surface of the lead body.

Abstract Now a days management of waste plastics becoming very difficult for us. These plastics waste is indirectly affect to our environment. From century we use plastics, day by day we rapidly use plastics. Generally, people use plastic or different products of plastics on large scale. Plastics are most durable and affordable material. Increasing the use of plastics in our daily life that may cause biggest cancer for our earth because plastics are not a biodegradable material. Million- and million-years plastic remain same in our earth. It is difficult to stop using plastic but we initiatives could be taken to manage plastic waste in other useful resources. So, the approach is taken to recycle the plastics waste into construction material. Waste plastic was collected from waste pickers and plastic dumping yards mostly. Then other materials like fly ash and sand were collected. After measuring specific gravity of plastic, sand and fly ash, the quantity required for each item was determined as the size of cube was known. Plastic aggregates are formed by crushing the plastic blocks in a manner so that plastic aggregates passing through 12.5mm sieve and retain on 10mm sieve. The aim of this research work is to use plastic aggregates as substitute of traditional aggregates either in road construction. Several tests have been conducted in laboratory which also enhances the sustainability of plastic aggregates in road construction in future.

The present technology is generally directed to methods of increasing coal processing rates for coke ovens. In various embodiments the present technology is applied to methods of coking relatively small coal charges over relatively short time periods resulting in an increase in coal processing rate. In some embodiments a coal charging system includes a charging head having opposing wings that extend outwardly and forwardly from the charging head leaving an open pathway through which coal may be directed toward side edges of the coal bed. In other embodiments an extrusion plate is positioned on a rearward face of the charging head and oriented to engage and compress coal as the coal is charged along a length of the coking oven. In other embodiments a false door system includes a false door that is vertically oriented to maximize an amount of coal being charged into the oven.
