Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because

joints‚ which means that they have a cavity in the joints that contains synovial fluid. Joints are not just made of bone‚ because if they were‚ friction would keep them from moving smoothly. The body uses cartilage and the synovial fluid to reduce friction in joints. Osteoarthritis happens when cartilage wears away over time and exposes bone to bone and increases friction‚ which is very painful. Synovial fluid is a fluid-like material that is present in many of the joints of the body. It serves the

Most organism are active in a limited temperature range The role of Enzymes in metabolism‚ their chemical composition and specificity on substrates Role of enzymes * Enzymes are organic catalysts. They are protein molecules that increase the rate of the reactions in living organisms. * Without enzymes‚ metabolic reactions at body temperatures would be too slow to produce sufficient energy to maintain life * Intracellular enzymes are used in the cells

Although a significant distinction exists between liquids and gases‚ both types of fluids obey the same laws of motion. In most cases of interest‚ a fluid can be regarded as continuum‚ i

ACCOUNT BALANCES For many purposes‚ it is necessary to determine the balance in an account. This is accomplished by adding the debits‚ credits‚ and determining the difference between the two sums. An account is said to have a debit balance if the sum of the debit entries to that account exceeds the sum of the credit entries. Conversely‚ an account has a credit balance if the sum of the credit entries exceeds the sum of the debit entries. Asset accounts normally have debit balances inasmuch as
