Hydrotreatment

Process for improving quality by catalytic hydrogenation, forming essentially linear n-paraffins.

Hydroisomerization

Catalytic process for transforming linear n-parafines under hydrogen into isomers of identical composition with a slightly branched carbon chain.

Corrosion-resistant alloy

Alloys with enhanced corrosion resistance (stainless steels, nickel-chromium-molybdenum alloys).

Pyrolysis

Pyrolysis, or thermolysis, is the chemical decomposition of an organic compound by significantly raising its temperature to obtain other products it did not contain.
