<p>Process for prodn. of methanol and opt. petrol from refuse, biomass and/or clarifier sludge, comprises (a) gasification by pyrolysis and oxidn., (b) taking off the gas contg. H2 and CO, (c) decomposing water into H2 and O2, (d) using the O2 in stage (a), (e) passing the gas mixt. from (b) to a methanol generator, in which (f) it is converted to methanol. Pref. heat generated in (a) and (f), and that from opt. exothermic conversion of the methanol to petrol, is used in (c). CO2 produced in (a) is separated, converted to CO and used in (f). Used for the elimination of solid wastes, with prodn. of liquid fuels. The process provides an alternative to scarce natural gas as a source of methanol and makes use of the thermal energy from pyrolysis etc.</p> |
