The flow of spent catalyst to the regenerator is regulated by a slide valve in the spent catalyst line. Since the cracking reactions produce some carbonaceous material (referred to as catalyst coke) that deposits on the catalyst and very quickly reduces the catalyst activity, the catalyst is regenerated by burning off the deposited coke with ...
Paradox was originally formed in late 1989 by members of the Danish group Trilogy (Bad Boy, Black Hawk, Tas, Pcsu, QRD) and the French group M.A.D (Olivier, Stinger, The Surge, Clash, Tagada). They began by cracking Amiga software. The original group shut down voluntarily in 1991 when the most active members joined Quartex, but was later reborn ...
Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminium industries and is particularly valuable because the electrodes must be replaced regularly. Needle coke is produced exclusively from either fluid catalytic cracking (FCC) decant oil or coal tar pitch.
The digital security firm Sophos exposed the scam, which begins with the following message making the rounds on Facebook: "I am part of the 98.0% of people that are NEVER gonna drink Coca Cola ...

Scams and confidence tricks are difficult to classify, because they change often and often contain elements of more than one type. Throughout this list, the perpetrator of the confidence trick is called the "con artist" or simply "artist", and the intended victim is the "mark".
The "spent" catalyst then flows into a fluidized-bed regenerator where air (or in some cases air plus oxygen) is used to burn off the coke to restore catalyst activity and also provide the necessary heat for the next reaction cycle, cracking being an endothermic reaction. The "regenerated" catalyst then flows to the base of the riser, repeating ...
From 2020 to 2022, an organized criminal group stole and then resold catalytic converters through the United States. The regional theft rings sent their stolen catalytic converters to DG Auto Parts in Freehold, New Jersey, who removed the precious metals from them and ground them into dust.
