Oct 01, 1996 Oct 01, 1996 The different steps for green coke calcination like: water evaporation, drying, VCM-evaporation, VCM burning, heating-up ramps, soaking period are calculated with a mathematical model. The results are compared with practical experiences for regular calcined coke production and with sampling programs during calcination process

    Aug 15, 2013 Aug 15, 2013 Green petroleum coke (GPC) is an oil refining byproduct that can be used directly as a solid fuel or as a feedstock for the production of calcined petroleum coke. GPC contains a high amount of volatiles and sulfur. During the calcination process, the GPC is heated to remove the volatiles and sulfur to produce purified calcined coke, which is

    Use of Thermally Desulfurized Shaft CPC for Anode

    Table 1 shows the results of a TDS trial in a rotary kiln with green petroleum coke (GPC) containing 4.6% S. The S loss under normal calcining conditions is 9–14% and it is important to note that this is not caused by TDS [1]. At higher calcining temperatures, the S loss increases to 30 and 47% due to TDS. This is accompanied by a drop in

    Coke Consumption - an overview | ScienceDirect Topics

    The volatile combustible matter of green coke ranges from as low as 6 to as high as 20 wt%, so for all these applications, the raw petroleum coke should be thermally upgraded prior to its use in a process called calcination to obtain CPC. Pet-coke calcining is therefore the process whereby “green coke” or raw petroleum coke is thermally

Static lab calcining always gives higher bulk densities than rotary kiln calcining since it is not possible to emulate the rapid heat up rate and devolatilization that occurs in a rotary kiln

    The process is carried out in a rotary kiln at temperatures exceeding 1300 deg C. Calcination of CPC is essentially a high temperature treatment in which the carbon to hydrogen ratio of RPC is increased from 20 to 1000 and above. Calcination is achieved by complete demoisturisation and

    Oct 01, 2015 We demonstrated a straightforward conversion of bio-oil distillate bottoms into calcined coke. The solid residue was subjected to calcination at 1200 C for 1 h under N 2 atmosphere. The dry calcined product contained 96–99% carbon, was free from sulfur ( 0.05% mass fraction), and contained a mass fraction of 0.2–1.1% ash

    Dec 20, 2014 The first rotary kiln for calcining GPC was used at Great Lakes Carbon in 1935,2 although rotary kilns had been used in the cement industry prior to that. Rotary kilns for CPC production are steel shells lined with high-temperature refractory brick; kilns can measure 30–85 m in length and 2.4–4.4 m in diameter
