Residual oils (petroleum) Heavy Fuel oil [A complex combination of hydrocarbons, sulfur compounds and metal-containing organic compounds obtained as the residue from refinery fractionation cracking processes. It produces a finished oil with a viscosity above 2cSt. at 100 °C.] A complex combination of hydrocarbons, sulfur compounds and metal-containing organic compounds obtained as the residue from refinery fractionation cracking processes. It produces a finished oil with a viscosity above 2cSt. at 100°C. 649-045-00-3

Residual oils (petroleum), oxidized A complex combination of organic compounds, predominantly high molecular weight carboxylic acids, obtained by the air oxidation of a solvent deasphalted residual oil.

Lubricating oils (petroleum), used, noncatalytically refined A complex combination of hydrocarbons obtained by refining waste oils without catalytic treatment with hydrogen. It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C20 through C50 and produces a finished oil with a viscosity of at least 100 SUS at 100°F (19cSt at 40°C).

Lubricating oils (petroleum), C>25, hydrotreated bright stock-based A complex combination of hydrocarbons obtained by treating solvent deasphalted residual oil with hydrogen in the presence of a catalyst in two stages with dewaxing carried out between stages. It consists predominantly of hydrocarbons having carbon numbers predominantly greater than C25 and produces a finished oil with a viscosity of approximately 440cSt at 40°C. It contains a relatively large proportion of saturated hydrocarbons.

Residual oils (petroleum), hydrotreated solvent dewaxed Baseoil - unspecified 649-491-00-9

Clarified oils (petroleum), catalytic cracked Heavy Fuel oil [A complex combination of hydrocarbons produced as the residual fraction from distillation of the products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly greater than C 20 and boiling above approximately 350 °C (662 °F). This stream is likely to contain 5 wt. % or more of 4- to 6-membered condensed ring aromatic hydrocarbons.] A complex combination of hydrocarbons produced as the residual fraction from distillation of the products from a catalytic cracking process. It consists of hydrocarbons having carbon numbers predominantly greater than C20 and boiling above approximately 350°C (662°F). This stream is likely to contain 5 wt. % or more of 4- to 6-membered condensed ring aromatic hydrocarbons. 649-011-00-8
