Process for producing shaped fuel and the shaped fuel per se

摘要

The present invention relates to obtain mold to produce solid fuel from waste. The mixture and waste containing binder that the fuel of molding includes drying and crushing solid fuel are from crude oil processing industry, such as greasy filth and/or recycle engine oil. The fuel also enumerates group and is selected from following groups (weight with % relative to mixture): lignosulfonates from 2 to 7% or molasses and/or the dehydration from 3 to 8% activated sludge and/or the clay from 3 to 10% and/or the original paraffin from 1 to 6%. % of the ratio between 10 and 32 weight adhesives of mold component is fed, surplus is selected from the group by ground solid fuel: wood sawdust, peat, dehydration fertilizer, dehydration clay pigeon rubbish, coke or coal dust, coal sludge, or mixtures thereof lignin. This method production moulded fuel includes mixed grinding solid fuel and adhesive, moulds the mixture, dries mechanograph (brick) with pressure of the brick between 1 and 30 MPa, temperature is lower than 300 °C. In the second embodiment, the fuel of molding includes the mixture of drying and crushing solid fuel thickened sludge, and the plant from wastewater treatment. There is the moisture content of a thickened sludge to represent the shaped fuel of from 13 to 18 weight % in 5 and 14%, surplus is selected from the group by ground solid fuel: timber or the waste of plant, lignin, peat, coke or coal dust, or mixtures thereof textile waste. This method production shaped fuel includes that ingredient mixes the activated sludge being concentrated solid fuel with the ground, the mechanograph of the dry molding of said mixture according to second embodiment. The activated sludge of the concentration is used for the water content of mixture under the pressure of 70 and 80 weight % and mixture molding, 0.Between 1 and 25 MPa. The mechanograph is that further progress is dry, is 50 °C and 180 in temperature and continues 1.5 to 0.4 hours or the mechanograph are to be dried at room temperature for lasting 5 to 30 hours.
