Abstract: A process for the preparation of low-molecular-weight olefins is characterized in that methanol and/or dimethyl ether together with recirculated hydrocarbons are brought into contact with a zeolite catalyst in order to convert methanol and/or dimethyl ether into low-molecular-weight olefins, and in that all or some of the reaction product, which remains after the resulting ethylene and propylene have been removed from the reaction product, is used as hydrocarbons for recirculation.

Abstract: PURPOSE:To obtain a high-quality artificial light-weight aggregate in a high yield by each setting an upper-limit burning temperature from water absorbing characteristics of an artificial light-weight aggregate and a lower-limit burning temperature from an unburned carbon amount contained in the artificial light-weight aggregate and burning a granulated article of coal ash at the set burning temperatures. CONSTITUTION:In burning of a granulated article of coal ash for laminating a granulated article of coal ash containing a coal content on a moving grate of a burning furnace isolated from the air and then producing an artificial light-weight aggregate by burning action with an oxygen-containing gas passing through the layer from upper side to the lower side, burning is carried out as follows: Lower-limit burning temperatures is set from water-absorbing characteristics of the artificial light-weight aggregate which is a burned article of the granulated article and an upper-limit burning temperature is set from an unburned carbon amount contained in the artificial light-weight aggregate and the granulated article is burned at the set temperatures. An optimum burning temperature area characteristic of each granulated article is precisely grasped and control of burning temperature, i.e., an O2 concentration control of a supply gas for burning is facilitated by measuring absolute dry specific gravity specified in JIS, an unburned carbon amount (carbon amount reduced on strong heating) contained in the artificial light-weight aggregate and water absorption important from the viewpoint of application of light-weight concrete. As a result, a high-quality artificial light- weight material can be produced in a higher yield.

Abstract: PURPOSE:To obtain an artificial light-weight aggregate satisfying excellent economicity as well as light aggregate weight, by adding inorganic powder having low apparent specific gravity to a main raw material composed of a clay mineral waste having self-sustaining combustibility, forming the mixture into a prescribed form and subjecting the product to self-sustaining combustion in a vertical kiln. CONSTITUTION:100pts.wt. of a main raw material composed of a clay mineral waste having self-sustaining combustibility (e.g. deposited sludge or coal ash) optionally added with 1-3% of pulp spent liquor or dust coal is added with 2-10pts.wt. of inorganic powder having low apparent specific gravity (

Abstract: PROBLEM TO BE SOLVED: To provide a method for recovering a superfine granular molybdenum sulfide catalyst contained in a liq. reaction product. SOLUTION: This method for recovering a superfine granular molybdenum sulfide catalyst contained in the distillation residue of a liq. reaction product includes (i) a combustion stage for burning the distillation residue at a temp. lower than the m.p. of the catalyst, (ii) a transfer stage for transferring the molybdenum oxide vapor formed in the combustion stage to its cooling and condensing stage and (iii) the cooling and condensing stage for cooling, condensing and solidifying the molybdenum oxide vapor transferred in the transfer stage.

Abstract: PURPOSE:To simply form a zeolite film without using a porous substrate or the like. CONSTITUTION:An independent zeolite film, consisting of zeolite alone, which is different from ratio of SiO2 and Al2O3 between the one face and the other face is obtained by performing hydrothermal synthesis for a hydrate gel containing Al2O3 and SiO2 and is >=50 in a molar ratio of H2O to SiO2 by using an autoclave under non-agitation at >=100 deg.C and

Abstract: PURPOSE:To obtain a high-quality artificial light-weight aggregate in a high yield by measuring softening characteristics of coal ash which becomes a main raw material and deciding a burning temperature based on the measured data in burning of a granulated article of coal ash. CONSTITUTION:In a burning method of a granulated material of coal ash carried out by laminating the granulated article of coal ash on a moving grate of a burning furnace isolated from atmosphere and burning the granulated article while forming a stream passing through the layer from the upper side to lower side, softening characteristics of coal ash which becomes a main raw material of the granulated article are measured and the granulated material is burned at a temperature capable of giving shrinkage ratio of the granulated article corresponding to 5-60% of maximum shrinkage ratio (shrinkage ratio in softening temperature).

Abstract: PURPOSE:To obtain feedstock for mullite ceramics in low costs by forming a mixture of deironated and decarbonized coal ash and alumina and firing the products. CONSTITUTION:Alumina is added to deironated and decarbonized coal ash, the mixture is formed and fired to give the subject material. The ash is reduced less than 2wt.% in iron and less than 0.5wt.% in carbon. The deironation treatment is carried out by using a magnetic separator, when needed, followed by treatment with hydrochloric acid or sulfuric acid. The decarbonization is effected in order to reduce carbon residue (including unchanged coal) by calcinating at 800 to 900 deg.C after deironation. Unsatisfactory pretreatment forms foams during the firing of the formed products. The residual iron causes colored (red brown) products with market value reduced.
