(Laboratory Manuel 2017) which will be done using a spectrophotometer. This is a method measuring both how much of a chemical substance is absorbed and the intensity of the light passing through the sample solution. (Vo, K. (2015). This also measures the concentration of NADPH which is a ...
precursors that can readily evolve to polycyclic aromatic hydrocarbons (PAHs), the typical coke species, through cyclization17and cross-linked mechanism18,19, accelerating catalyst deactivation20. Therefore, such dual-role of HCPs impedes achieving superior light olefins selectivity while maintaining long c...
The highlight of the event was when the Coke Ambassadors, together with key Coke representatives in each venue, poured buckets of ice in the coolers – which made the temperature drop to 3˚ Celsius. It was a eureka moment as the audience realized that the key to getting the perfect Coke...
An attempt is made to find a simple method for dealing with a typical diffraction problem, which would throw some light on the following questions: the rea... HM Nussenzveig - 《Philos.trans.roy.soc.london.ser.a》 被引量: 38发表: 1957年 An integrated experimental environment for distribute...
Specific steps include: replacing fuel oil (light oil) with clean coal, petroleum coke, and natural gas in the power, petroleum and petrochemical, [...] undpcc.org 具体步骤包括:用清洁煤、石 油焦(炭) 和天然 气取代燃油 (轻质油),用于发 电、石油和石化、冶金、建材行业和交通业;加 快...
gas. Low-caloric-value gas requires a relatively long residence time, whereas high-caloric-value gas requires a measurably shorter residence time. A high proportion of very heavy hydrocarbons and, perhaps, coal dust requires a long residence time; light hydrocarbons require a shorter residence time...
Its structure is blocky and its color is light black. It is a fuel and reducing agent for ferroalloys, fertilizers, calcium carbide, blast furnace injection, and other applications. As a new type of fluidized bed boiler fuel, it has a relatively high fixed carbon content; low ash, aluminum...
The textures of bio-coal, coke, and bio-cokes were investigated using a light optical microscope (LOM, Nikon ECLIPSE E600 POL, Tokyo, Japan). The samples were mounted in epoxy resin and the surfaces were polished before the studies. The chemical composition of coke prepared in the laboratory...
In recent years, several new techniques have been developed to produce propene, including catalytic cracking of heavy oil and light olefins, olefin disproportionation, naphtha catalytic cracking, propane dehydrogenation, methanol to olefins, etc. [7,8]. Among the above techniques, the catalytic ...
The liquid output of the flash separator consists mainly of condensed water, methanol, and solubilized compounds due to the high pressure, while the recycled gas stream mainly contains light compounds (CO, CO2, H2, N2). A second flash separator under a pressure of 2 bar is used to separate...
