Embodiment Construction

[0029]A characteristic of this invention refers to the nature of the paraffin load used which is from waxes obtained from renewable sources, mixed with mineral waxes.

[0030]The wax load obtained from a renewable source is submitted to successive treatments over different types of catalysts, each destined to perform a specific function in each stage of the process.

[0031]In a broad sense, the process of the invention for hydroconversion of a mixture of loads of waxes from renewable sources treated together with a load of mineral waxes includes the following procedures and operational conditions:[0032]a) hydrotreatment of a stream made up of a mixture in a proportion in mass of waxes obtained from renewable sources of between 1% and 100% and mineral waxes of between 99% and 0% wt / wt. This stream is hydrotreated in a hydrotreatment reactor, under the usual conditions of hydrotreatment which involve an operating pressure within a range of between 7 MPa and 15 MPa, temperature of the catal...

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...
