The medicaments are dispersed throughout the solution by the bases. Petroleum jelly‚ which is one of the major components in producing ointments‚ is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25)‚ originally promoted as a topical ointment for its healing properties. After petroleum jelly became a medicine chest staple‚ consumers

Alkanes are saturated hydrocarbons. They contain only carbon-carbon and carbon-hydrogen single bonds. They are the least reactive of the organic compounds. The main source is crude oil. Hydrocarbon- a compound consisting only of hydrogen and carbon Saturated- Contain single carbon -carbon bonds only Unsaturated-contains a C=C bond Petroleum fraction- mixture of hydrocarbons with a similar chain length and boiling range The general formula for is CnH2n+2 (for ring alkanes is CnH2n)

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

depleted there is no more available for future needs. Also considered non-renewable are resources that are consumed much faster than nature can create them. Fossil fuels (such as coal‚ petroleum‚ and natural gas)‚ types of nuclear power (uranium) and certain aquifers are examples. Natural resources such as coal‚ petroleum‚ oil and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being consumed. Eventually natural resources will become too costly to harvest

produced from domestic‚ renewable resources. Biodiesel contains no petroleum‚ but it can be blended at any level with petroleum diesel to create a biodiesel blend. It can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel is simple to use‚ biodegradable‚ nontoxic. Biodiesel is better for the environment because it is made from renewable resources and has lower emissions compared to petroleum diesel. It is less toxic than table salt and biodegrades as fast as
