| PATENT CLAIMS |
Hydrocarbon alkylation process using a catalytic mixt contg a HF-agent complex, wherein the complex is formed from complexing agent contg Lewis base site contg Group 5A element & producing an acid soluble oil (ASO) by-prodt, wherein ASO is rejected from the process & the HF-agent complex is recovered & recycled to alkylation zone - Alkylating a hydrocarbon substrate with a hydrocarbon alkylation agent in the presence of HF & HF-agent complex in alkylation zone & producing reactor effluent stream contg alkylate & ASO - Separating the effluent stream into an acid effluent stream contg ASO, HF, & HF-agent complex & hydrocarbon effluent stream contg alkylate - Forming by-prodt stream from portion of acid effluent stream wherein by-prodt stream contains ASO, HF, & HF-agent complex & by-prodt stream has molar ratio of HF per Lewis base site > 5:1 - Selectively removing portion of HF & ASO from by-prodt stream to produce HF-enriched stream contg HF & ASO & an HF-depleted stream, wherein said depleted stream contains ASO, HF & complex & has HF/Lewis base = 3:1- 5:1 - Sepn HF-depleted stream into hydrocarbon phase enriched in ASO & an acid phase depleted in ASO & contg complex - Passing portion of hydrocarbon effluent stream & portion of HF-enriched stream to a fractionation zone & recovering from said zone a recycle stream contg HF & prodt stream contg alkylate & ASO - Recycling portion of acid phase & portion of recycle stream to alkylation zone - Rejecting the hydrocarbon phase from the process |
