Abstract

An integrated process for producing alkylbenzenes, sulfonated alkylbenzenes and/or alkylcyclohexanes from syngas is disclosed. The process involves subjecting syngas to Fischer-Tropsch conditions. Fractions rich in C.sub.6-8 and C.sub.18-26 hydrocarbons are isolated from the resulting product stream. The C.sub.6-8 fraction is subjected to catalytic reforming conditions to form aromatics. The C.sub.18-26 fraction may include sufficient olefins for use in an alkylation reaction with the aromatics. Optionally, the fraction may be subjected to dehydrogenation conditions to provide additional olefins. The resulting olefins are reacted with the aromatics in an alkylation reaction to yield alkylbenzenes. Unconverted olefins, paraffins, and aromatics can be obtained from the product stream via fractional distillation and recycled to form additional products. The alkylbenzenes can be hydrogenated to yield alkylcyclohexanes, which are useful as synlubes or as components in lube oil compositions. Alternatively, the alkylbenzenes can be sulfonated, and the resulting sulfonated alkylbenzenes used, for example, as detergents and/or dispersants.
