The calcined pseudoboehmite samples with the addition of peptizing agent (HNO 3) were also characterized using the FT-IR spectroscopy of pyridine adsorption. As shown in Fig. 5 , the samples prepared with different HNO 3 /Al ratios exhibit sole Lewis acidity and no Brönsted acid sites were observed on these samples, verifying that the peptizing agent is not able to generate Brönsted acid
27/6/2019· This table of the conductivity and resistivity of many common materials will help you learn about the concepts and factors that affect conductivity. Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current.

1.1 This test method covers the X-ray fluorescence spectrometric determination of total sulfur and trace metals in samples of raw or calcined petroleum coke. Elements determined using this test method are listed in Table 1. 1.2 Detection limits, sensitivity, and
Needle-shaped petroleum coke (raw coke) of ultra-high power, high-power graphite electrode raw materials. Since the petroleum coke content of coking in China''s petrochemical plants is getting higher and higher, it has supplemented 4A-6# for a small amount of carbon (electrode paste, carbon brick, hode carbon block, etc.) products, most of which are used in the fuel industry. .
and RD of calcined petroleum coke (CPC) resulting from TDS has previously been attributed to an increase in micro-porosity [4]. The best analytical method to charac-terize this is high pressure mercury (Hg) intrusion porosimetry. The pore size distribution curves
The bed resistance of carbonaceous solids has been measuredinseveral different laboratory systems using a four-point probe technique, It is a function of gas velocity, column diameter, particle size and other properties of the bed material. Also, as temperature is
1.1 This test method covers the determination of bulk density of a representative 2 kg sample of calcined petroleum coke, after vibration to increase compaction, using a semi-automatic apparatus. 1.2 The procedure is applied, but not limited, to particles passing through a 4.75 mm opening sieve and retained on a 1.18 mm opening sieve.
compact coination coke cutting unit. A pilot hole is drilled down through the coke in the drum using high pressure water, and then the coke is cut out with a drilling bit with horizontal water nozzles. Roy Diwoky while at Standard Oil Whiting was one of the
Carbographite Industrial PTE.LTD - Professional graphite electrode,carbon electrode paste,carbon raiser,Calcined petroleum coke,Graphitized petroleum coke,Refractory supplier from China.
The calcined petroleum coke, obtained by carboniza-tion of heavy oil fractions and oil residue, is used as filler in the production of carbon anodes. Petroleum coke must be of optimum density, ensuring sufficient porosity for interaction with the binder, goodity and
Petroleum coke (petcoke) is a carbonaceous solid that delivered from oil refinery coker units or other cracking processes. Coking processes that can be employed for producing petcoke include contact coking, fluid coking, flexicoking and delayed coking. Other coke
G. Jacobs et al./Applied alysis A: General 188 (1999) 79–98 81 at which temperature the pressure increased substan-tially. After sublimation, the alyst was ramped to 130 C and held for 15min to ensure that virtually all of the Pt(AcAc)2 was sublimed. The
A method for preparing phosgene by using the alyst of claim 1 or the alyst obtained by the method of claim 4, wherein: carbon monoxide and chlorine gas are reacted in the multi-tubular reactor of a fixed bed packed with the alyst, wherein the alyst is
The collection of the approximately 240 kg of calcined petroleum coke was under the direction of R.B. Murzyn, Environmental Coordinator, VENCO. The gross sample was jaw crushed and subsequently pulverized using ceramic plates to pass a 250 µm (60
The ethanol dehydration to ethylene over alumina alysts prepared by solvothermal and sol-gel methods was investigated. Also, a commercial alumina was used for comparison purposes. The results showed that the alytic activity depends on the properties of
