121 Effect of reaction temperature on coking deactivation of a modified HY zeolite catalyst for alkylation of benzene with propylene was investigated.

122 Company Set coking, coal, electricity, iron alloy, chemical industry, railway transportation and international trade, etc. , as one industry.

123 In this paper, the current practising and developing biochemical techniques of removing phenol from coking and gasworks wastewater are introduced.

124 The method of removal of thiophene in coking benzene and lightbenzene by chloromethylation is studied.

125 The relationship between coking and deactivation of ZSM-5 type zeolite catalyst has been reviewed systematically.

126 The price of coking coal under the contracts will surge initially by about 55 per cent, according to one Japanese steelmaker.

127 Some waste plastics are added to mixed coal and coking with a small coke oven, then tar yield, coke yield, coke granularity, coke intensity of I rotational kettle and coke ash is analyzed.

128 The anthracite with proper size was mixing to use in coal- to- coke conversion, not only increasing the coking power, but also cutting down the coal consumption with the better economic benefits.

129 The coking and deactivation of virgin naphtha aromatization catalyst are studied on isothermal reactor.

130 Township enterprises in trade , in commerce, mining, coking, quarrying, food service industry.

131 The present quality standard for metallurgical coke and its concrete execution, and the demand of coking and iron-making industries to it are narrated and analyzed simply, some suggestions offered.

132 The Australian state accounts for more than 50 per cent of coking coal supply to the global seaborne market, on which steel mills in Asia, and to a lesser extent,[sentencedict.com/coking.html] western Europe rely.

133 Castries oil is a high-residual carbon, high-asphaltene crude oil. Its vacuum residue is prone to producing shot coke during coking processing.

134 It can be used in various operations of heavy and residual oil coking process.

135 A composite catalyst has been commercially used for the hydrocracking of Daqing heavy gas oil containing 50% of coking gas oil.

136 Through the test and comparison of ethylene cracking of hydrogenated delayed coking gasoline and regular grade straight-run gasoline, it is showed that the former can be used as ethylene stock.

137 The smoke suppressing effect of organic barium salt, a product of the reaction between barium bioxide and naphthenic acid in coking gasoline, as a diesel oil additive was studied.

138 The method avoids product fractionation in the prior coking fractional distillation column, thereby greatly reducing investment and operation cost.

139 Under the heavy duty operation, the internal coking of tube caused by local tube over heating is an universal problems for delayed coking furnace.
