HYDROCRACKED BASE OILS
HYDROCRACKED BASE OILS
The main advantages of Hydrocracked Base Oils over the traditional solvent neutral are as follows:
Chemical structure stability Chemical structure independent from crude oil quality
Stability Excellent oxidation stability in the presence of suitable additives
Low sulphur content Sulphur content lower than 0.01%wt
Low nitrogen content Very low content of nitrogen compounds (traces)
Low aromatics Cut-down of aromatics content
Light colour Hydrocracked oils have light colour
Non-toxic They do not contain potentially carcinogenic poly-aromatic hydrocarbons.

HC BASE OILS
1. HC BASE OILS
HC base oils are classified according to ATIEL (API) into Group I (HC 22),
Group I”+” ( HC 68) and Group II HC 20 and HC 46).
HC base oils find their use in wide variety of automotive and industrial oils; in industrial area they are especially suitable in hydraulic, turbine and compressor oils formulation. Together with appropriate additives it is possible to meet the most demanding requirements of present lubrication and extent machine component lifetime.
Main advantages:
• low volatility
• very low sulphur and nitrogen content
• light colour
• high oxidation stability and affinity for additives
• viscosity index up to 115

HC VERY HIGH VISCOSITY INDEX BASE OILS
2. HC VERY HIGH VISCOSITY INDEX BASE OILS
VHVI HC base oils are classified Group III according to ATIEL (API).
VHVI HC base oils represent modern technology for top lube oil production. These oils have excellent affinity for additives, performance packages, viscosity modifiers, depressants, etc. VHVI HC are ideal base for formulation of high quality oils particularly for latest vehicle specifications and also for modern industrial hydraulic, turbine, compressor, gear, and other application.
VHVI HC base oils are fully comparable with VHVI and XHVI oils on the world market.
Main advantages of VHVI HC for production of high quality engine oils:
• very low volatility close to synthetics (PAO)
• very high viscosity index
• excellent low temperature performance
• good thermal and oxidation stability
• very low content of aromatics and poly-aromatics
• very high degree of sulphur and nitrogen compounds reduction
• high saturated hydrocarbons level

HC LOW-VISCOSITY OILS
3. HC LOW-VISCOSITY OILS
HC low viscosity oils are successfully used in metal-working, hydraulic and shock absorber fluids, automatic transmission fluids, transformer and insulating oils, mould release oils etc.Main advantages:• very narrow distillation cuts, 15-35 °C wide• low aromatics content• very low sulphur and nitrogen content• low volatility• light colour• naturally low pour and cloud point• relatively environmentally friendly• biodegradability 40-45 % according to CEC-L-33-A-93, 40-60 % OECD 301B

N BASE OILS
4. N BASE OILS
N base oils can be classified as Group I” +” due to low sulphur content, higher saturated hydrocarbons content and high viscosity index.
Typical characteristics of N base oils:
• high degree of sulphur and nitrogen compounds reduction
• light colour
• low volatility
• higher viscosity index than typical for group I
• higher content of saturated hydrocarbons than typical for group I
N base oils are especially recommended for formulations of both engine and industrial oils, e.g. for hydraulic, compressor, preserving, hardening and other oils.
