Different zinc dialkyldithiophosphate (ZDDPs) exhibit different volatilities and have different effects on automotive emissions control alysts. The ZDDPs and their respective decomposition fragments that have low volatility will have a correspondingly lower detrimental effect on coustion emissions control systems, because there are simply fewer phosphorous atoms that will pass through the

Calorific value - COALspot

2017-4-18 · The calorific value Q of coal is the heat liberated by its complete coustion with oxygen. Q is a complex function of the elemental composition of the coal. Q can be determined experimentally using calorimeters. Dulong suggests the following approximate formula for Q when the oxygen content is less than 10%: Q = 337C + 1442(H - O/8) + 93S,

2017-11-2 · Calcium as an excellent reducing agent is being widely used in many metallurgical operations. Calcium is used as a reducing agent in the extraction of other metals like uranium [29, 30], zirconium [31], and tho-rium. It is also used in the preparation of TiC [32] and niobium powders [33]. Petroleum coke is used because

Experimental investigation on the flowability …

2016-3-11 · ABSTRACTThe flowability properties of two carbonaceous powers (anthracite coal and petroleum coke), including angle of repose (AOR), Hausner ratio (HR) and powder compressibility (C), etc., were determined. The effects of particle size, external moisture content (MC) and power type on powder flowability properties were investigated. The results indie that as the powder particle size
