Abstract
Abstract Process for the simultaneous hydrogenation and deodorisation of at least one product from the group consisting of fats and oils, wherein said product is treated with carbon dioxide at a temperature of from 100° to 250°C and a pressure of from 150 to 300 atmospheres in the presence of a hydrogenation catalyst, and hydrogen. The fats and oils hydrogenated and deodorised in this process are used in the manufacture of margarine.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
72 words
A process for the simultaneous hydrogenation and deodorisation of at least one product from the group consisting of fats and oils, wherein said product is contacted with carbon dioxide in an amount effective for the deodorisaton and containing hydrogen in an amount effective for the hydrogenation, at a temperature of from 100° to 250°C and a pressure of from 150 to 300 atmospheres in the presence of a catalyst for the hydrogenation.
Claim 2
Dependent Claim
72 words
A process for the simultaneous hydrogenation and deodorisation of at least one product from the group consisting of fats and oils, wherein said product is contacted with carbon dioxide in an amount effective for the deodorisaton and containing hydrogen in an amount effective for the hydrogenation, at a temperature of from 100° to 250°C and a pressure of from 150 to 300 atmospheres in the presence of a catalyst for the hydrogenation.
