| 摘要 |
The invention relates to fuel, in particular to suspended aqueous-alchoholic fuel on the basis of black coal, and can be used for production of liquid fuel, suitable for transportation by pipeline from production station to combustion place. The task of the invention – to increase suspension sedimentation stability and rheological stability over time. The claimed content of aqueous-alcoholic coal suspension, containing (wt.%): coal 55-65; alcohol of the fractions C- C20-40; rheological additive – sodium salt of sulfonaphthaleneformaldehyde (dophene) 0.6-0.9; stabilizer - sodium carbonate 0.1-0.4; water – the rest. The claimed aqueous-acloholic suspensions are specified by high sedimentation stability (10-12 days) and rheological stability (effective viscosity is 1.3-1.5 Pa·s for 10-12 days). |
