Biochar Production, Characterization and Utilization

Pohořelý Michael, doc. Ing. Ph.D. ( poh...@vscht.cz)
Trakal Lukáš, Doc. Mgr. Ph.D.
Biochar is essentially charcoal, i.e., a carbon-rich porous material.
The work will be focused on the production, characterization and utilization of biochar.
The properties of biochars produced from different types of biomass will be characterized in cooperation with the institutes of the Academy of Sciences of the Czech Republic, primarily according to the European Standard EBC (European Biochar Certificate), international standardization IBI (International Biochar Initiative Biochar Standards), and the forthcoming Europen legislation 2016/0084 (COD). The additives will be further analysed using specific analytical methods (XRD, XRF, SEM-EDX, XPS, FTIR, Raman spectroscopy, NMR, porosimetry, thermal analysis methods etc.).
The use of the biochar will be investigated by laboratory tests and real applications in collaboration with CULS. The partners of the project are, besides the mentioned research institutions, also private farmers, the Botanical Garden in Prague, and the substrate producers.

Carbon black production from wastes with the aid of thermal plasma

Pohořelý Michael, doc. Ing. Ph.D. ( poh...@vscht.cz)
Jeremiáš Michal, Ing. Ph.D. ( jer...@vscht.cz)
Since the industrial revolution, carbon black (CB) production steadily increased to reach a current production of 12 million tons per year (2017). Last news on the Worldwide Carbon Black Market says the demand will continue to grow and it is expected a production of 20 million tons by the year 2020. [1] The current manufacturing processes of the CB could be classified into two categories: incomplete combustion and thermal decomposition of hydrocarbons. [2] Plasma processes for the production of carbon black have the advantage to produce in one step carbon black and H2 without direct emissions (CO2, SOx, NOx, etc.) connected with the combustion processes used for the standard production of carbon black. Also, indirect emissions can be prevented by the use of electricity produced by renewable sources (possibly off-peak electricity). The PhD project will explore the possibilities of the production of carbon black from waste materials. It will consist of a thorough literature review, and a 150 kW demonstration of carbon black production by thermal plasma from selected wastes under carefully selected conditions. The desired result is a proposal of a complex technological process of the production of CB from available and useful waste materials including an economical perspective.

Material compatibility in the environment of fuels containing a bio-component.

Macák Jan, doc. Ing. CSc. ( mac...@vscht.cz)
Matějovský Lukáš, Ing. Ph.D. ( luk...@vscht.cz)
Content of a bio-component (e.g. bio-ETBE, bioethanol, bio-butanol) changes significantly physical-chemical properties of automotive fuels. With the increasing content of a bio-component the polarity, conductivity and water absorptivity of the fuel increases. Consequently, corrosion aggressivity is increased. One of possibilities to supress corrosion degradation is application of corrosion inhibitors.
The subject of this work is corrosion and corrosion inhibition study in the environment of automotive fuels containing a bio-component.
