An outstanding organic chemist and organizer of science in the Donetsk region (to the 100th anniversary of Academician LM. Lytvynenko)

January 12 marks the 100th anniversary of the birth of a prominent Ukrainian scientist in the field of physical and organic chemistry, a talented organizer of science, winner of the State Prize of Ukraine in Science and Technology (1993, posthumously), winner of the L.V. Pisarzhevsky Prize of the NAS of Ukraine (1969), the organizers and first rector (1965-1968) of the Donetsk National University, one of the founders and first chairman (1971–1978) of the Donetsk Scientific Center, founder and director (1975-1983) of the Litvinenko Institute of Physical Organic and Coal Chemistry of the NAS of Ukraine, Doctor of Chemical Sciences (1961), Professor (1962), Academician of the NAS of Ukraine (1965) Leonid M. Lytvynenko.

Application prospects of Irkutsk region thermal coals

The purpose of the paper is to assess application directions and prospects of Irkutsk region power generating coals for the needs of electric and heat power engineering with regard to the possible export of elect rical energy to the countries of South-East Asia, and use as raw materials for coal chemistry needs. The research is carried out using the methods of system analysis involving analysis and synthesis, formalization and concretization, structuring and restructuring, classification. It is the first time when the category of local power generating coals is distinguished under the analysis of the balance reserves of thermal coals. Their feature is low-quality and remoteness from settlements and transportation lanes. Their resource estimate is also given – 0.54 billion tons. An estimate of the recoverable reserves of local coals is obtained: it is 260 million tons. The potential level of local coal production is calculated. A retrospect of consumption trends of regional thermal coals is given and possible application directions are considered in the long run. It is shown that the most demanded direction is the use of coals for energy needs, mainly at thermal power plants. The calculated volumes of coal consumption of two export TPPs, Mugunskaya and Ishideiskaya, are respectively 11 and 6 million tons. According to the authors' calculations, the percentage of electrical energy generation at coal -fired TPPs depending on its export variant implementation can increase by 1.5 – 2.1 times as compared with the level of 2019. Availability of significant reserves of power generating coals in the region makes them a reliable source of energy resources for the electric and thermal power industry, including the export of electrical energy and a promising raw material for the needs of coal chemistry. Potential capacity of coal mining is estimated at 50-60 million tons per year, including 6.5 million tons of local coals. Production potential of coal significantly exceeds its demand both at present and in the future.

Survey of zinc metal processing capability with coal-chemistry activated carbon by chemical K2CO3

Seed coat macadamia preparation of activated carbon with chemical agent K2CO3 from macadamia shells as per ratio: K2CO3: distilled water = 1:1:10ml, optimal temperature condition 6500C and burning time 60 minutes. Efficiency removal of zinc (II) in wastewater efficiency (53.42%) with the concentration of 25ppm, conducted a survey at pH = 4.5 with 1.8g/l of carbon, treated in 100 minutes. Survey results have similarities with other studies and are applicable to application removal of zinc (II) in wastewater.
