The present invention provides a processing method which can process biomass resources to a carbide having a uniformity and including a large amount of high-carbon charcoal, can hold down an initial cost while capable of executing a large amount of process (for example, 100 ton per day), has a low running cost while can suppress a fuel consumption to a significantly low level, and can continuously carbonize a object having a high water content, having an unstable shape and having a high viscosity such as a sewage sludge even being a simple structure. The carbonization processing method has the steps of (i) continuously supplying a processing object M which is not preliminarily treated, or a processing object M which is formed at a predetermined magnitude by a preliminary treatment such as a fragmentation, a water content reduction or the like, from an upstream side of a cylindrical rotary kiln in which a spiral carrier wall is provided in an inner peripheral surface in an entire length and an agitating wall cutting across the carrier wall is formed in the carrier wall in a middle portion from the upstream side at a predetermined unit amount while rotating the rotary kiln, (ii) blowing a flame in an inner portion of the rotary kiln from a downstream side in a carrying direction of the rotary kiln in the state (i), and stopping the blowing of the flame if the processing object M is ignited within the rotary kiln, (iii) supplying an air necessary for burning a combustible gas generated from the processing object M to an inner portion of the rotary kiln from a downstream side, and self burning the combustible gas without supplying any fuel, (iv) sucking a gas generated in the inner portion of the rotary kiln from the upstream side of the rotary kiln so as to detoxify and discharge, and (v) discharging the carbide of the processing object M from an outlet in the downstream side of the rotary kiln so as to cool by executing the operations in the (i) to (iv).

An exhaust gas cleaning method capable of maintaining an optimum NOx purification ratio in the continuously regenerative range of DPF in an exhaust gas cleaning system (1) having an NOx purification function and a PM purification function combined with each other and the exhaust gas cleaning system (1). In the exhaust gas cleaning system (1), NOx purification by an NOx occlusion / reduction type catalyst (42) and PM purification by a continuous regeneration type DPF (41) are preformed for exhaust gas from an internal combustion engine. When the temperature (Tent) of the exhaust gas flowing in the DPF (41b) exceeds the self-burning temperature (Tent0) of PM and the differential pressure increasing rate (dP) of a differential pressure across the DPF (41b) exceeds a specified determination value (dP0), at least either of a control to reduce the frequency of enriching the exhaust gas and a control to reduce the degree of richness is performed in a catalyst regenerative control for regenerating the NOx occlusion / reduction type catalyst (42).

The invention discloses self-promoted combustion type electronic paste and a preparation method thereof. The self-promoted combustion type electronic paste comprises a solid phase and an organic binding phase, wherein the solid phase comprises metal powder, a metal oxide, glass powder and a thermal decomposition oxidization agent, and the organic binding phase comprises resin, a solvent and an additive. The preparation method comprises the steps of (a) preparing the glass powder; (b) preparing the organic binding phase; and (c) preparing the paste. By material combination and a corresponding preparation method, the prepared paste has the following advantages that: 1, the thermal decomposition oxidization agent is added into the paste, the resin in the paste can be oxidized by the oxidization agent during the paste sintering process, the carbon content in a sintered film is reduced, and the performance stability of the paste after formation is improved; 2, K2O generated after decomposition of the thermal decomposition oxidization agent in the paste melts into the glass powder, and the glass property such as thermal expansion and dielectricity can be adjusted so that the demands of different substrates are satisfied; and 3, MnO2 is generated after the decomposition of the thermal decomposition oxidization agent in the paste, and the square resistance of the paste can be flexibly adjusted according to special demands.

The invention relates to a low-smoke halogen-free flame-retardant anti-aging cable material for cables. The cable material is characterized in that the cable material comprises the following components in parts by weight: 20-50 parts of EPDM (ethylene-propylene-diene monomer), 50-80 parts of EVM (ethylene vinyl acetate rubber), 2.5-5 parts of a vulcanizing agent, 1.5-6 parts of a vulcanizing additive, 2-8 parts of an anti-aging agent, 10-30 parts of a plasticizer, 0.5-1.5 parts of a coupling agent, 15-30 parts of a reinforcing agent, 20-40 parts of a filling agent, and 50-70 parts of a flame retardant. According to the invention, because raw materials which do not produce dense smoke in the process of self burning, and do not produce dense smoke during chemical reactions thereof, and can absorb smoke are selected, the smoke density of cables in the process of burning is effectively reduced.
