The alkanes dehydrogenation reaction is a reaction involving the breaking of ( ) bonds, and its general formula is ( ). 64. To increase the ethylene yield in the pyrolysis products,. The common methods adopted are ( ), ( ), ( ). 65. When production requirements dictate a reduction in the feed rate to the pyrolyzer, the amount of dilution steam decreases accordingly; the purpose of this is ( ). 61. ( ) and ( ) are effective means of liquefying gases. Cooling and pressurization 62. The purpose of using secondary steam injection in the pyrolysis furnace is ( ). Preventing coking of the feedstock during heating and gasification in the convection section. 63. The alkanes dehydrogenation reaction is a reaction involving the breaking of ( ) bonds, and its general formula is ( ). C–H CnH2n+2 CnH2n+ H2 64. To increase the yield of ethylene in the pyrolysis products. The common methods adopted are ( ), ( ), ( ). Increase the pyrolysis temperature, reduce the residence time, and lower the hydrocarbon partial pressure. 65. When the feed rate to the pyrolyzer needs to be reduced due to production requirements, the amount of dilution steam is correspondingly ( ), and the purpose of this is ( ). Improve prevention of increased secondary reactions resulting from prolonged residence time due to reduced feed rate
61 Cooling and pressurization 62 Preventing coking of the feedstock during heating and gasification in the convection section 63 C—H, C2H2n+2, C2H2n+H2 64 Increasing the cracking temperature, reducing the residence time, and lowering the hydrocarbon partial pressure 65. Increase to prevent increased secondary reactions due to prolonged residence time caused by a reduced feed rate

61. (Cooling) and (pressurization) are effective methods for liquefying gases. 62. The purpose of using secondary steam injection in the cracking furnace is to prevent coking of the feedstock during heating and gasification in the convection zone. 63. The alkanes dehydrogenation reaction is a reaction involving the breaking of ( ) bonds, and its general formula is (C—H → C2H2n+2 + H2). 64. To increase the ethylene yield in the pyrolysis products,. The common methods adopted are (increasing the pyrolysis temperature), (reducing the residence time), and (lowering the hydrocarbon partial pressure). 65. When production requirements dictate a reduction in the feed rate to the pyrolyzer, the amount of dilution steam is increased accordingly; this is done to prevent an increase in secondary reactions resulting from the longer residence time caused by the reduced feed rate.
