Abstract

C + H2O = CO + H2 – Syngas of Fischer-Tropsch process.

4 C +4 H2O = 4 CO + 4H2, combined with reversible Boudouard reaction – 2CO = C +CO2 at mild conditions, so

4C + 4 H2O = 2 C + 2 CO2 + 4 H2, and with Sabatier reaction – CO2 + 4H2 = CH4 + 2H2O, so totally

2 C + 2 H2O = CH4 + CO2 + 108.0 kJ, created by 0.275 C combustion in the air, can be summarized for economics estimation in

2.275 C + 2 H2O = CH4 + 1.275 CO2.

Being supposed domestic cost USD 100.0/ /ton of C for Central Europa, CH4 is 2.275 * 12 * 100 / 16  = USD 170/ ton CH4, so  USD 120/ 1000 m3 .

If CO2 is USD 30 /ton, so CH4 is USD 46.0 /1000 m3

CV-2023

 CV-2023, David Judbarovski, systems engineering, principle inventor, Israel cooperation and consulting Being very productive principle inventor and investigator on a firm basis of my work in wide spectra engineering and economics, I am sure that energy and production have to be and are ready to be green & cheap & abundant & inexhaustible, while all materials and parts and tools for that purpose can be recyclable. Short professional CV I was born in former USSR in 1939. 1962 –I was graduated as Dipl.-Eng. in Mechanics and Technology with emphasis on control and automation in chemical industry and mathematic simulation. 1962 –I was starting my professional career in systems engineering, at first with emphasis on applied mathematics methods. Through my life I had a duty experience in course in: (1) air traffic control, (2) microbiological industry, (3) pulp and paper industry, (4) technology of microelectronics, (5) capital construction, (6) typical design, (7)...

Russian black business

  Кремль продолжает продвижение кампании по отбеливанию имиджа России за рубежом. И заявления "хороших" россиян, которых Запад вытащил из российских тюрем в рамках обмена, – часть этой спецоперации. "Россия и Путин — это не одно и то же", "санкции должны быть направлены на преступников и режим Путина, а не на граждан РФ", да и вообще Украине "надо садиться за стол переговоров" с Россией.   Нет, это не очередное изложение заявки сумасшедших кремлевских вождей или их пропаганды.   Это первые   заявления   освобожденных из российских тюрем российских "оппозиционеров", сделанные 2 и 3 августа в Германии.  Они сильно возмутили украинское и европейское общество
