Process to obtain biolubricants and bioparaffins by hydroprocessing mixtures of wax obtained from renewable resources and waxes of mineral origin

Abstract

Process for hydroconversion of loads of mixtures of waxes from renewable resources that may be made up of waxes of mineral origin or waxes of animal origin, that may be used in their pure form or mixed in any proportion, that may optionally be combined with loads of hydrocarbons of mineral origin, as is the case of waxes obtained from petroleum, by industrial treatment. This mixture flow is submitted to a hydrotreatment and hydroisomerization / hydrofinishing process and the referenced process takes place under the usual hydroconversion conditions, in the presence of a hydrogen stream and hydroconversion catalysts, resulting in obtaining products referred to as biolubricants and bioparaffins, that present characteristics of being biodegradable and less of an environmental pollutant.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is based upon, claims the benefit of, priority of, and incorporates by reference, the contents of Brazilian Patent Application No. PI PI 0605006-9 filed Nov. 30, 2006.FIELD OF THE INVENTION[0002]This invention belongs in the field of hydroconversion processing, more specifically to the hydroconversion of wax mixture loads obtained from renewable resources such as waxes of vegetable or animal origin, combined or not with waxes of mineral origin, such as waxes obtained from petroleum, to obtain products with biodegradable characteristics, that may be called biolubricant oils and bioparaffins.BACKGROUND OF THE INVENTION[0003]Growing concerns about the environment and the ever more restrictive regulations to control environmental pollution have caused researchers to search for innovative and economically viable alternative raw materials to use in the industrial and energy production context, for the purpose of obtaining raw ma...

Benefits of technology

[0024]One of the waxes from plants used in this process is from Carnauba, which is a plant with high economical and social value, low cost and potentially high profitability. Native palm acclimated to the region of northeast Brazil referenced to as a semi-arid region, is being explored especially on large properties through traditional association with subsistence cultures.

[0027]The best Carnauba waxes available on the market contain between 20% and 50% of Carnauba in combination with clarifying agents and natural oils, offering lubrication, good electrical properties and are in conformity with FDA (Food and Drug Administration) regulations. Its melting point is within a range of 83° C. and 86° C. Its principal application is in additives to increase the melting point and reduce plasticity.

Problems solved by technology

However, development of this technology has still not advanced much and this invention offers an innovative alternative for this purpose.
