Abstract
The invention relates to a method for the production of n-alkanes from mineral oil fractions and fractions from thermal or catalytic conversion plants, containing cyclic alkanes, alkenes, cyclic alkenes and/or aromatics. The invention further relates to a catalyst for carrying out said method.
Claims21
A process for the manufacture of a reaction product comprising one or more n-alkanes from an initial product comprising one or more mineral oil fractions comprising 80 to 95% by weight aromatic compounds and 1 to 20% by weight olefin compounds or pyrolysis gasoline, said process comprising:
- converting one or more cyclic hydrocarbons with a zeolite catalyst having a spaciousness index SI≦20 and a modified constraint index CI*>1, where the one or more cyclic hydrocarbons include hydrocarbons produced by hydrogenation of the one or more mineral oil fractions,
- wherein during the converting
- the H2 pressure is 5 to 200 bar,
- the temperature is 150 to 550° C.,
- the concentration (WHSV) is 0.1 to 20 h−1, and
- the one or more cyclic hydrocarbons are converted to n-alkanes.
A process comprising
- treating one or more mineral oil fractions comprising from 80 to 95% by weight of one or more aromatic compounds and 1 to 20% by weight of one or more olefin compounds or pyrolysis gasoline, with a catalyst to form one or more n-alkanes,
- wherein said catalyst comprises a zeolite having a spaciousness index SI≦20 and a modified constraint index CI*>1, wherein the catalyst comprises from 0.0001 to 0.1% by weight of a metal selected from the group consisting of Pd, Rh, Ru, Ir, Os, Cu, Co, Ni, Pt, Fe, In, Mo, W, V and mixtures thereof.
