CZ32461U1 - Marine fuel containing material from the pyrolysis of tires - Google Patents

Description

Technical field

The technical solution relates to marine fuel containing tire pyrolysis material, which comprises a residual component from secondary oil processing, a mixture of gas oils and material derived from the pyrolysis of used tires.

BACKGROUND OF THE INVENTION

The Marine Environment Protection Committee (MEPC), acting under the auspices of the International Maritime Organization (IMO), adopted in April 2018 a strategy to reduce the greenhouse gases produced by the combustion of marine fuels. The aim is to reduce CO2 emissions by at least 40% by 2030 and up to 70% by 2050, in line with the 2015 UN Conference on Climate Change (COP21 - 2015 United Nations Climate Change Conference). The reduction of total greenhouse gas production (GHG - GreenHouse Gases) is set at at least 50% by 2050. The IMO envisages adopting a new greenhouse gas strategy by 2023.

In most refineries, the existing marine fuels are produced from petroleum products (residual components from secondary oil processing processes and gas oil blends), ie exclusively fossil sources. Their disadvantage is that they do not meet the planned requirements to reduce unwanted greenhouse gas emissions by reducing the content of those fuel components that come from non-renewable (fossil) sources.

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

The essence of the technical solution

Marine fuel containing tire pyrolysis material is characterized by containing

52.5 to 59.5 wt. % residual components from secondary petroleum processing, 22.5 to 25.5 wt. % gas oil mixture and 15 to 25 wt. material derived from waste tire pyrolysis.

The advantage of marine fuel containing tire pyrolysis material according to the technical solution is that it contains material made from unwanted waste - used tires, thereby efficiently utilizing waste materials.

Another advantage of marine fuel containing tire 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.

Examples of technical solutions

Example 1

Marine fuel contains 59.5 wt. residual components from secondary oil processing,

25.5 wt. % blend of gas oils and 15 wt. of pyrolysis of tires.

For marine fuel containing 15 wt. material from pyrolysis of tires were determined basic qualitative properties. The results are shown in the following table (Table 1).

Table 1 - Results of determination of parameters of marine fuel containing 15 wt. of pyrolysis of tires

Parameter Unit Value ISO 8217 requirement Density at 15 ° C [kg-m- ³ ] 660 max .. 700 Kinematic viscosity at 50 ° C [mnri-s ¹ ] 998 max .. 1010 TSA [wt%] 0.07 max 0.10 MCRT [wt%] 19.25 max 20.00 Point of ignition [° C] 79 min. 60 Content of AI + Si [mg-kg ² ] 7.2 max. 60 Contents [mg-kg ² ] 213 max .. 450 Contents Na [mg-kg ² ] 21.3 max 100 Ash content [wt%] 0.1 max 0.150 Acid number [mg KOH / g] 0.15 max 2.5

Comment:

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 the acids per gram of sample analyzed.

From these results it is evident that marine fuel containing 15 wt. of tire pyrolysis 20 has qualitative parameters corresponding to the relevant standard and can therefore be used as fuel for maritime transport.

Example 2

Marine fuel contains 52.5 wt. residual components from secondary oil processing,

22.5 wt. % blend of gas oils and 25 wt. of pyrolysis of tires.

For marine fuel containing 25 wt. material from pyrolysis of tires were determined basic qualitative properties. The results are shown in the following table (Table 2).

Table 2 - Results of Determination of Marine Fuel Parameters Containing 25 wt. of pyrolysis of tires

Parameter Unit Value ISO 8217 requirement Density at 15 ° C [kg-m ³ ] 600 max .. 700 Kinematic viscosity at 50 ° C [mnri-s ¹ ] 992 max .. 1010 TSA [wt%] 0.05 max 0.10 MCRT [wt%] 18.80 max 20.00 Point of ignition [° C] 72 min. 60 Content of AI + Si [mg-kg ² ] 6.4 max. 60 Contents [mg-kg ² ] 188 max .. 450 Contents Na [mg-kg ² ] 18.8 max 100 Ash content [wt%] 0.09 max 0.150

Parameter Unit Value ISO 8217 requirement Acid number [mg KOH / g] 0.12 max 2.5

From the above results it is evident that marine fuel containing 25% by weight of tire pyrolysis material has qualitative parameters corresponding to the relevant standard and can therefore be used as marine fuel.

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

Industrial applicability

Marine fuel containing tire pyrolysis material according to the invention is industrially useful as fuel for shipping.
