CNSL Refinery for Biofuel

Cashew Nut Shell Liquid (CNSL)

Cashew nut tree is a flowering plant, belongs to the family of as poison sumac (Scientific name: Anticardium occidentale).

Nuts are the seed in the fruit and its shell has a high calorific value of 18.84 MJ/kg (Gaur & Reed 1995).

The oil from the shell is suitable for power generation by direct combustion but needs refinery process to remove particles.

The production per unit area in tropical countries is known to 800-1,000kg/ha.

BioHitech Refinery System

BioHitech refinery system produces Methylation free biofuel from the CNSL by the use of natural ore catalysts and centrifugal refinery systems.

Impurities in CNSL are effectively removed and continuous biofuel production is produced.

  1. Kinematic viscosity at 50 ℃: 23.72mm2/s
  2. No glycerin in biofuel.
  3. Sulfur content < 0.13%
  4. Acid value (pH): Neutral

Palm oil vs. CNSL

Palm Oil

  1. The oil is extracted from a fruit (not from a residue).
  2. Cultivation for oil increases CO2 generation.
  3. Deforestation by expanding cultivation area
    (destruction of environment and ecosystem).
  4. Conflicts with local residents
    (employment & human right issues).

CNSL

  1. 100% recycle of residue from the nut husk (waste).
  2. No extra cropping process to get raw material.
  3. Contract with farmers already in cashew nut business.
  4. No environmental issues.
  5. Stable raw material supply.
