Description

Technical field

The present invention relates to a marine fuel comprising a plastic pyrolysis material which comprises a residual component from a secondary oil processing, a mixture of gas oils and a material derived from the pyrolysis of used plastics.

BACKGROUND OF THE INVENTION

In most refineries, the existing marine fuels are produced from petroleum products, in particular from the residual component from secondary oil processing processes and gas oil blends, ie exclusively fossil sources. The disadvantage of existing marine fuels is that they contain too much undesirable sulfur, which burns with high air pollution. The planned requirements to reduce unwanted greenhouse gas emissions from marine fuel combustion will support the new International Maritime Organization's rule from 2020 to reduce the permissible sulfur content in fuel oils from 3.5% by weight. to 0.5 wt%, which is a reduction of about 80 to 86%. One possibility of reducing the content of this undesirable component is the addition of alternative or renewable raw materials that do not contain sulfur.

Said disadvantages are at least partially eliminated by marine fuel containing material from the pyrolysis of plastics according to the invention.

The essence of the technical solution

A marine fuel containing plastic pyrolysis material is characterized in that it contains 55 to 65 wt. % residual components from secondary oil processing, 22 to 26 wt. % of a mixture of gas oils and 8 to 22 wt. material derived from the pyrolysis of waste plastics.

The advantage of marine fuel containing plastic pyrolysis material according to the technical solution is that it contains a material made from unwanted waste - used plastics, thus also efficiently utilizing waste materials.

Another advantage of marine fuel containing plastic pyrolysis material according to the technical solution is that it meets the basic quality parameters given by the relevant standard [ISO 8217: 2017 Petroleum products - Fuels (class F) - Specifications of marine fuels] for conventional marine fuel listed in the following tables.

Examples of technical solutions

Example 1

Marine fuel containing plastic pyrolysis material contains 64.5 wt. % residual components from secondary oil processing, 25.5 wt. % blend of gas oils and 10 wt. plastic pyrolysis material.

For marine fuel containing 10 wt. of the material from pyrolysis of plastic were determined the basic qualitative properties. The results are shown in the following table (Table 1).

- 1 GB 33561 U1

Table 1 - Basic quality characteristics of marine fuel containing 10 wt. material of plastic pyrolysis for ISO-F-RMK 380 category

Parameter Unit Value ISO 8217 requirement Density at 15 ° C [kg-m ³ ] 997 max .. 1010 Kinematic viscosity at 50 ° C [mm ² -s'] 340 max .. 380 TSA [wt%] 0.02 max 0.10 MCRT [wt%] 18.07 max 20.00 Point of ignition [° C] 73 min. 60 Content of AI + Si [mg-kg ’] 5 max. 60 Contents [mg-kg ’] 258 max .. 450 Parameter Unit Value ISO 8217 requirement Contents Na [mg-kg ² ] 24 max 100 Ash content [wt%] 0,073 max 0.150 Acid number [mg KOH / g] 0.5 max 2.5

Notes on tables:

TSA (Total Sediment Accelerated) is the total sediment content of marine fuels after chemical aging.

MCRT (Micro Carbon Residue Testing) is a measurement that indicates a tendency to coke formation.

The acid number is a measure of the acidity given by the amount of potassium hydroxide in milligrams required to neutralize acids per gram of sample analyzed.

From these results it is evident that marine fuel containing 10 wt. The material from plastic pyrolysis has qualitative parameters corresponding to the relevant standard and can therefore be used as fuel for maritime transport.

Example 2

Marine fuel containing plastic pyrolysis material contains 57.5 wt. % residuals from secondary oil processing, 22.5 wt. % blend of gas oils and 20 wt. plastic pyrolysis material.

For marine fuel containing 20 wt. of the material from pyrolysis of plastic were determined the basic qualitative properties. The results are shown in the following table (Table 2).

-2 GB 33561 U1

Table 2 - Basic quality characteristics of marine fuel containing 20 wt. material from pyrolysis of plastics for ISO-F-RMG 180 category

Parameter Unit Value ISO 8217 requirement Density at 15 ° C [kg-m ³ ] 990 max .. 991 Kinematic viscosity at 50 ° C [mm ² -s'] 180 max 180 TSA [wt%] 0.01 max 0.10 MCRT [wt%] 16.13 max 18.00 Parameter Unit Value ISO 8217 requirement Point of ignition [° C] 74 min. 60 Content of AI + Si [mg-kg] 4 max. 60 Contents [mg-kg ² ] 230 max .. 350 Contents Na [mg-kg ² ] 21 max 100 Ash content [wt%] 0,066 max 0.150 Acid number [mg KOH / g] 1.0 max 2.5

From these results it is evident that marine fuel containing 20 wt. The material from plastic pyrolysis has qualitative parameters corresponding to the relevant standard and can therefore be used as fuel for maritime transport.

It is further evident from both examples that increasing the addition of plastic pyrolysis material reduces density, viscosity, TSA, MCRT, selected metal content and ash content, thereby improving the quality of marine fuel containing plastic pyrolysis material.

Industrial applicability

Marine fuel containing plastic pyrolysis material according to the invention is industrially usable as fuel for shipping.
