Most known acidic zeolites rapidly deactivate within a few minutes and have selectivities primarily for cracked products with low yields of gasoline and diesel fuel range hydrocarbons. All previous catalysts have little variation in oligomerization selectivity and give nearly identical yields with zeolite crystal size and number of Bronsted acid sites. There is a need for a catalyst that converts small olefins into larger fuel range hydrocarbons suitable for diesel and jet fuels.

Researchers at Purdue University have developed a modified boron catalyst containing zeolite that has higher oligomerization selectivity for conversion of small olefins into higher molecular weight hydrocarbons. This zeolite gives significantly higher yields of oligomerized products with less cracked products, leading to higher yields of fuel products. This catalyst offers a longer life and can produce diesel range hydrocarbons at higher pressures. When operated at higher pressures, higher yields of high quality diesel and jet fuels resulted.

Advantages:
-Longer life
-Improved stability
-Improved selectivity
-Decreased cracking
-Higher output
-Higher quality

Potential Applications:
-Oil companies
-Technology companies
-Fuel production plants
-Jet and diesel fuels
