Embodiment 1

[0166] according to figure 1 , raw materials of biological origin and plastics are supplied continuously in two parallel paths via silos and heating screws to the disperser and from there directly to the reactor. No catalyst was added. Do not add carrier oil after system start-up.

[0167] From the tests carried out the following balance was obtained:

[0168] Mass balance: 800 kg of dry biomass + 200 kg of dry mixed plastic yields 300 kg of product oil, equivalent to 360 liters of product oil (17.5% yield of biosource, 80% yield of plastic, product oil density 0.833kg / L). There is no need to add additional carrier oil, because the oil production method of the present invention is balanced. The difference to 1000 kg consists of the effluent of gas, product water and char.

[0169] Energy balance: 800kg×5kWh / kg+200kg×12kWh / kg6400kWh input calorific value; 360L×10kWh / L=3600kWh output oil calorific value; 3600kWh / 6400kWh=56.3% energy yield. The energy difference compared to ...

Embodiment 2

[0171] according to figure 2 , raw materials of biological origin and plastics are supplied continuously in two parallel paths via silos and heating screws to the disperser and from there directly to the reactor. No catalyst was added (neither in R1 nor R4). Do not continue to add carrier oil after system start-up.

[0172] The bottom phase is continuously withdrawn from R1 (100-1000 L / h; solid consistency: 5-20% by mass, temperature: 50-380 °C) and hydrogenated in R4 at a positive pressure of 0-10 bar (ultrasonic parameters: frequency: 18 -30kHz, power parameters: 300-3000W / L). The resulting reaction product is recycled to reactor R1.

[0173] According to the tests carried out, the formation of char was reduced compared to Example 1.

Abstract

The invention relates to a method for producing fuels from solid biomass and plastics, characterized in that in a first step biomass and plastics are dispersed at 300-400 DEG C in the presence of recycled carrier oil; in a second step the obtained mixture is brought to reaction at 300-400 DEG C; in a third step the arising gaseous, liquid, and solid products are separated from each other and optionally further processed; wherein the ratio of biomass to plastic is in the range of 80:20 to 10:90 wt % and wherein the method is conducted without externally supplying carrier oil and wherein the method is conducted without externally supplying catalyst. The invention further relates to systems for carrying out the method.

Description

technical field [0001] The present invention relates to a method for producing fuel from a mixture comprising biomass and plastic and a system for carrying out the method. Background technique [0002] Various methods have been proposed according to the prior art for the production of fuels from raw materials of biological origin, however, these methods have various disadvantages. [0003] Wieser (WO 2006 / 131293) describes a catalytic process for the production of fuels from biologically derived raw materials using carrier oils. [0004] Koch (EP 1538191) describes a process for the preparation of fuels from residual materials by catalytic depolymerization using a specific reactor. The disadvantage of this method is, inter alia, that specific reactors which are susceptible to disturbances have to be used. [0005] Goessler et al. (WO 2010 / 031803) describe a method for obtaining fuel from a mixture containing biomass and heavy oil. A disadvantage of this method is, inter a...
