| Summary, etc. |
Ethylene is an unsaturated hydrocarbon which undergoes numerous reactions and is a higWy unstable molecule, hence ethylene is not feasible to be use as fuels for car engines. Ethylene is volatile thus extra precautions must be taken when storing, handling and transporting ethylene. So it is wise if ethylene is converted to higher hydrocarbons liquid for safe handling, and might as well produce liquid hydrocarbons within the ranged of gasoline composition. Banned on plastics due to environmental effect will lessen the consumption of ethylene, thus results in abundance of ethylene and reduce the market price of ethylene due to low demand. This will promote a process to convert ethylene into liquid hydrocarbons through oligomerization process. The objective of this research is to study the performance of ethylene oligomerization over zeolite catalyst to produce higher hydrocarbons liquid. Due to time constraint, zeolite was not synthesized instead zeolite-A was purchased and selected as the catalyst for oligomerization of ethylene at elevated temperatures. Performance of ethylene conversions to liquid hydrocarbons (LHC) is via a single step reaction in a fixed-bed-micro reactor over 1 gram of zeolite-A catalyst. Ethylene (99.9%) purity react at atmospheric pressure and temperature start at 400°C with ethylene flow rate of 50 ml/min. Characterization using XRD and FTIR analysis reveal that zeolite-A is a small pore catalyst and will only allowed linear hydrocarbon to enter the pore and will not produce molecules with 6 or more carbons as molecules of this size will not fit into the small pores of zeolite. It was also predicted that zeolite-A has lower acid site than ZSM-5 and thus will reduce the ability of oligomerization process, and also being observed that coking occurred when temperature increase to 800°C, which conclude that product selectivity factor has higher possibility to limit oligomerization of ethylene to higher hydrocarbons liquid. -Author |
