Disclosed herein are a fuel composition comprising a fuel oil added with at least two kinds of soaps selected from cerium, neodymium and lanthanum soaps and a fuel additive comprising an organic solution that contains at least two kinds of soaps selected from cerium, neodymium and lanthanum soaps.

Fuel composition and fuel additive

A process for producing an alkanesulfonic acid is described, which comprises causing sulfur dioxide and oxygen to act on a saturated hydrocarbon under illumination with light in a substantially water-free reaction system, wherein photo-sulfoxidation of the saturated hydrocarbon is performed as a reaction mixture in the reaction system is held in contact with sodium sulfite.

Process for producing alkanesulfonic acids

A catalyst suitable for cracking heavy oils can be obtained by baking nickel-containing ore at a temperature between about 850.degree. C and about 1200.degree. C.

Catalyst for treating heavy oils

A raw synthetic caking coal having a volatile matter content of 20 - 70%, H/C (atomic ratio) of 0.60 - 1.20 and a maximum fluidity of greater than 40 ddpm is produced by coking heavy hydrocarbons. Synthetic caking coal having a volatile matter content of 20 - 40%, H/C (atomic ratio) of 0.60 - 0.75, a maximum fluidity of greater than 40 ddpm and a Free-Swelling-Index of greater than 3 is produced from the raw synthetic caking coal by stripping said raw synthetic caking coal with steam or light hydrocarbons.

Process for producing synthetic caking coal and binder pitch

Synthetic coking coal is produced by coking heavy hydrocarbons at a temperature greater than the temperatures which initiate cracking in the coker, and by removing the gaseous and liquid products from the coker at accelerated velocities. The thermally cracked oil produced in the coking reaction can be hydrodesulfurized to produce a low sulfur fuel oil.
