  A Low Cost High Energy Density Carbon Black Fuel Mix For Heat Engines
Titel: A Low Cost High Energy Density Carbon Black Fuel Mix For Heat Engines
Auteur: Steinberg, Meyer
Verschenen in: Energy sources. Part A, Recovery utilization and environmental effects
Paginering: Jaargang 9 (1987) nr. 3 pagina's 161-171
Jaar: 1987
Inhoud: An efficient economically attractive process is described for production of carbon black and the by-product hydrogen from any carbonaceous raw material and especially from coal. The HYDROCARB process consists of two steps. The first step is the hydropyrolysis of coal to produce methane and the second step is the thermal decomposition of the methane to carbon black and hydrogen, part of which is recycled. The process is essentially a cracking of the coal to its elements C and H2, removal of oxygen as water, leaving behind the ash and sulfide residue. The carbon black can then be mixed either with a liquid hydrocarbon or an alcohol in a carbon-fuel-mix (CARBOL1NE-CFM) or with water to produce a carbon-water-mix (CARBOL1NE CWM). A 65% CWM fuel has been produced which has an energy density of 108,000 Btulgal. Addition of 50% carbon black to kerosene jet fuel increases its energy density from 140,000 to 170,000 Btulgal. Some of the rheological and combustion characteristics of carbon black, CWM, and CFM and its potential use in heat engines including diesels and turbines are described. Compared to conventional synfuel processes, the HYDROCARB process is much simpler and more economical.
