This study presents a life cycle analysis to model these potential benefits by comparing a metallurgical coke technical pathway with technical pathways of gasification coke integrated with different chemical productions. The results show that producing gasification coke is a feasible technical pathway for the transformation and development of the coke industry. However, its economic feasibility depends on the price of cokes and coals. The gasification coke production has higher energy consumption and CO2 emissions because of its lower coke yield. Generally speaking, using gasification coke to produce F-T oils has higher economic benefits than producing methanol, but has lower energy efficiency and higher carbon emissions.

Paul Great Lakes Carbon Corporation Port Arthur, TX Prepared for presentation at the AIChE 1998 Spring National Meeting New Orleans, LA March 8-12, 1998 Topical Conference on Refinery Processing Tutorial Session: Delayed Coking Paper 29a Copyright 1998 Great Lakes Carbon Corporation UNPUBLISHED March 9, 1998 1 ABSTRACT Great Lakes Carbon Corporation has worked closely with refineries producing delayed coke in all forms, fuel grade (shot or sponge), anode grade (sponge), and electrode grade (needle) since start-up of the company's first calcining operation in 1937. With on-going research in the area of delayed coking since 1942, Great Lakes Carbon (GLC) has operated delayed coking pilot units including an excellent large-scale pilot unit with a coke drum 0.3 meter (1 ft) diameter by 2.1 meters (7 ft) long and has developed physical models which explain coke formation in coke drums. Knowledge of commercial delayed coking units as well as that of the GLC Pilot Delayed Coker is used in this tutorial paper to describe the formation and uses of the three types of structures of delayed petroleum coke: needle, sponge, and shot. Troubleshooting tips are included on many aspects of the delayed coking drum cycle including: steam stripping, water quenching, coke cutting, drum warm-up, and drum switching technique. Suggestions and descriptions of delayed coking unit hardware are included. The objective of this tutorial paper is to acquaint the non-refinery technologist and further the knowledge of refinery personnel with the delayed coking operation, delayed coking unit hardware, types of coke that can be produced, coke formation models, and the uses of petroleum coke.

Academic Editor: Keith Hohn Received: 30 December 2013 / Accepted: 12 September 2014 / Published: 26 February 2015 Abstract: Deactivation of heterogeneous catalysts is a ubiquitous problem that causes loss of catalytic rate with time. This review on deactivation and regeneration of heterogeneous catalysts classifies deactivation by type (chemical, thermal, and mechanical) and by mechanism (poisoning, fouling, thermal degradation, vapor formation, vapor-solid and solid-solid reactions, and attrition/crushing). The key features and considerations for each of these deactivation types is reviewed in detail with reference to the latest literature reports in these areas. Two case studies on the deactivation mechanisms of catalysts used for cobalt Fischer-Tropsch and selective catalytic reduction are considered to provide additional depth in the topics of sintering, coking, poisoning, and fouling. Regeneration considerations and options are also briefly discussed for each deactivation mechanism. Keywords: heterogeneous catalysis; deactivation; regeneration 1. Introduction Catalyst deactivation, the loss over time of catalytic activity and/or selectivity, is a problem of great and continuing concern in the practice of industrial catalytic processes. Costs to industry for catalyst replacement and process shutdown total billions of dollars per year. Time scales for catalyst deactivation vary considerably; for example, in the case of cracking catalysts, catalyst mortality may be on the order of seconds, while in ammonia synthesis the iron catalyst may last for 5–10 years.

  • AP 42 12.2 Coke Production
    12.2 Coke Production 12.2.1 General Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is "coked", or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke. Most metallurgical coke is used in iron and steel industry processes such as blast furnaces, sinter plants, and foundries to reduce iron ore to iron. Over 90 percent of the total metallurgical coke production is dedicated to blast furnace operations. Most coke plants are co-located with iron and steel production facilities. Coke demand is dependent on the iron and steel industry. This represents a continuing decline from the about 40 plants that were operating in 1987. 12.2.2 Process Description1,2 All metallurgical coke is produced using the "byproduct" method. Destructive distillation ("coking") of coal occurs in coke ovens without contact with air. Most U. S. coke plants use the Kopper- Becker byproduct oven. These ovens must remain airtight under the cyclic stress of expansion and contraction. Each oven has 3 main parts: coking chambers, heating chambers, and regenerative chambers. All of the chambers are lined with refractory (silica) brick. The coking chamber has ports in the top for charging of the coal. A coke oven battery is a series of 10 to 100 coke ovens operated together. Figure 12.2-1 illustrates a byproduct coke oven battery. Each oven holds between 9 to 32 megagrams (Mg) (10 to 35 tons) of coal. Offtake flues on either end remove gases produced. Process heat comes from the combustion of gases between the coke chambers.

  • Reasons for the Rapid Switch from Coal to Oil KOBORI, Satoru (Nagoya University)
    Japan’s Energy Policy During the 1950s (Kobori) Japan’s energy policy during the 1950s: reasons for the rapid switch from coal to oil KOBORI, Satoru (Nagoya University) Introduction The energy revolution, the switching of energy resources from domestic coal to foreign petroleum, was one reason underlying the golden age of 1960s capitalism. It universally affected developed countries. In 1959-1960, both the Organization for European Economic Co-operation (OEEC) and the Japanese government declared officially that cheap foreign oil made the energy revolution inevitable1; thereafter their coal mining industries began a long decline. However, we can also find various underlying factors of the energy revolution and attempts to alter its course. This paper specially examines the characteristics of Japan, which industrialized more rapidly than any other country at that time. Table 1 shows three important points distinguishing Japan. First, Japan was industrialized country that was most dependent on oil in 1973: Japan’s rate of energy self-sufficiency was lowest. Second, the Japanese energy revolution was more rapid than that of Italy, a similarly energy-dependent nation. Whereas oil’s share of energy use in Italy was already 31.78% in 1950, that in Japan was only 6.15%; this percentage was the lowest aside from that of West Germany. Third, Japan’s rapid energy revolution had occurred not only during the 1960s but also during the 1950s. The Japanese dependence on oil became 38.32%, which rivaled the dependency of Italy and the U.S., which had shown high dependence on oil even before WW II. Therefore, the purpose of this paper is to present analyses of the reasons for the rapid Japanese energy revolution, particularly addressing Japanese energy policy during the 1950s.
