The phosphorus and potassium contents of the char obtained from thermal conversion forest residues can limit its utilization as an alternative fuel reducing agent to substitute coal/coke in steelmaking industry. In this study, ash transformation release K P during single-pellet different types (i.e., bark, twigs, bark+twigs) were investigated with aid a vertical tube furnace (Macro-TGA) at temp...

The normal supply of energy is related to the stable development economy and society. Forecasting consumption helps prepare for energy. In study forecasting, different scholars have used forecasting models. This paper uses five-year data in Beijing-Tianjin-Hebei region grey fractional FGM(1, 1) model analyze next six years. Then, three places predicted. advantage score that it can get more accu...

Alga-lysing bacteria have been paid much attention to in recent years. In this study, the alga-lysing strain P05 which was isolated from an immobilizing biosystem was immobilized by coke and elastic filler, forming two biological reactors. The removal efficiencies of algae, NH4(+)-N and organic matter using the two reactors were studied. The results showed that strain P05 was an ideal algal-lys...

Extracts of soots obtained from various sources were applied to the skin of mice in an effort to identify carcinogens in these mixtures and to link these materials to the etiology of human cancer. Samples of coal chimney soot, coke oven materials, industrial carbon black, oil shale soot, and gasoline vehicle exhaust materials have been examined by this method. The studies reported here have bee...

Pyrolysis of low density polyethylene (LDPE) by equilibrium fluid catalytic cracking (FCC) was studied in a stirred reactor under different process parameters. In this work, the effect of process parameters such as degradation temperature (420-510°C), catalyst/polymer ratio (0-60%), carrier gas type (H2, N2, ethylene, propylene, Ar and He), residence time and agitator speed (0-300 rpm) on the c...

A new method for the determination of the spatial distribution of metal surface area within bimodal micro-/meso-porous solids has been developed. This novel technique involves incorporating a nonane pre-adsorption stage between two successive chemisorption experiments. This method has been used to probe the distribution of platinum amongst the micropores and mesopores of a range of bi-functiona...

Reaction of the airways to inhaled Berodual was evaluated in two groups of metallurgists surveilled by systematic, complex medical examinations for appx. 25 years: 31 coke oven and 31 cold-rolling mill workers. All subjects under examination were active smokers, smoking more than 20 cigarettes a day. The frequency of ventilatory disorders (central bronchi obturation, small bronchi obturation, a...
