Abstract
The invention relates to a method for producing latent heat storage material from linear alcohols by dehydrating to dialkyl ethers or to olefins, and hydrogenating to paraffins and dialkyl ether as a latent heat storage material.
Claims10
A method for the production of paraffins produced from linear alcohols, comprising:
- purifying fatty alcohols by distillation in order to obtain at the stage of the alcohol
- fatty alcohols that are more than 93% by mass linear,
- fatty alcohols that have more than 95% by mass even numbered chain lengths, and
- fatty alcohols that exclusively have a certain C-number at more than 95% by mass,
- followed by dehydrating of above linear fatty alcohols to obtain olefins and subsequently hydrogenating the olefins to obtain paraffins,
- wherein the paraffins are used as a phase change material absorbing heat when liquefying and emitting stored heat when solidifying.
