WebThe reason for hazy appearance is due to the precipitation of dissolved waxes. The presence of wax makes the oil appear cloudy at room temperature. The oil normally becomes cloudy in 5–6 h but with proper dewaxing the oil remains clear after 24h of storage at 0˚C. Dewaxing is carried out by chilling the oil up to 10-15°C into the crystallizers. WebHaving the right dewaxing catalysts minimizes yield loss and ensures on-spec renewable jet fuel. Isomerization catalysts make the difference. If the temperature gets sufficiently low, there is a risk of wax crystals in the processed feedstocks which can block fuel filters and lines. The resulting fuel starvation will mean engines stop running.
