Definitions
- the invention relates to a process for the treatment of organic solids as a fuel for fixed bed gasifier according to claim 1 and a method for operating a fixed bed gasifier for producing a product gas with such treated organic solids according to claim 16.
- EFB fibrous waste
- fibrous organic solids such as plants - claim 3. These may be both renewable resources and plant waste, the z.
- fibrous organic solids such as plants - claim 3.
- these may be both renewable resources and plant waste, the z.
- the production of alcoholic beverages or as so-called EFB in palm oil production is obtained.
- the following organic solids can be prepared:
- Seagrass, algae Particularly effective is the treatment of fibrous grassy solids, such as A-round Donax, Napier grass, Switch grass, Miscanthus, hay, straw; fibrous fruit peel such as mangosteen, jackfruit, durian, breadfruit, prickly pear, coconut, banana, cocoa peel, pineapple, citrus fruit; Palm fibers such as coconut, date, hemp palm; and fibrous fruit kernels, such as mango kernels, coconut, avocado.
- fibrous grassy solids such as A-round Donax, Napier grass, Switch grass, Miscanthus, hay, straw
- fibrous fruit peel such as mangosteen, jackfruit, durian, breadfruit, prickly pear, coconut, banana, cocoa peel, pineapple, citrus fruit
- Palm fibers such as coconut, date, hemp palm
- fibrous fruit kernels such as mango kernels, coconut, avocado.
- the preferred range is between 50g and 200g of organic solids per liter of fresh water. It is desired to minimize the fresh water consumption - claim 8.
- the amount of the additive is between 1 and 10 percent by weight based on the mass of organic solids - claim 9.
- the mixture of water, additive and organic solids is preferably heated to a temperature of 40 ° C to 80 ° C and preferably to 50 ° C to 70 ° C and - claim 10.
- the heat for heating the mixture of water, additive and organic solids is preferably provided by waste heat from the fixed bed gasifier - claim 1 1.
- the residence time of the organic solids in the liquid is preferably between 1 and 20 hours and preferably between 1 and 5 hours - claim 12.
- the residence time can be reduced by mechanical stirring of the mixture of water, additive and organic solids - Claim 13.
- the fiber length after the crushing step is between 1 cm and 10 cm, and preferably between 3 cm and 5 cm - claim 14.
- EFB was comminuted to a fiber length between 3 cm and 5 cm in the comminution step.
- EFB was comminuted to a fiber length between 3 cm and 5 cm in the comminution step.
- 1 g quicklime (CaO) was added to 11 seawater and 10g EFB.
- the mixture of EFB, seawater and additive was heated to about 60 ° C and the EFB was soaked for 20 hours.
- the EFB was removed and mechanically dried to a water content of about 50w% and then thermally to a water content of about 15 w%.
- This dried EFB was then pelleted.
- These pellets are used as pourable biomass particles in a fixed bed gasifier according to WO 2016/091835 A1.
- the use was unproblematic.
- the ash melting point rose above 1 100 ° C compared to untreated EFB and the ash content fell below 10w% of the EFB used.
- the coconut palm is found on almost every tropical or subtropical island. This plant and especially the fibrous fruiting bodies are thus an ideal fuel for the decentralized energy supply of remote islands.
- the use of coconut waste in many places offers the potential to replace the existing power supply with diesel generators.
- Especially the fibrous fruit husks of coconut fall, especially in the decentralized production, as waste. These make up about 35% by weight of the fresh coconut.
- the coconut fibers are used to make fabric materials, briquettes and fertilizer. However, this is only possible with the central processing of the nut. With the above method, the very low melting ash components of the coconut fibers can be stabilized. This applies to both the fruit fibers and the trunk of the palm itself.
- seawater is heated to about 75 ° C in a ratio of 1/100 coconut fibers are added (for example, 10g to 1 liter) and in turn in a ratio of 1 to 10 based on the biomass share CaO, z. B. in the form of cement, added to the mixture.
- This mixture is brewed for 5 hours.
- the result is a soft ash without formation of melt.
- Such a raw material can be processed decentrally in small mills into pellets and used with the biomass gasifier described in the patent for the provision of electricity and also entire decentralized power grids in the island operation.
