A new crystalline molecular sieve designated SSZ-95 is disclosed. In general, SSZ-95 is synthesized from a reaction mixture suitable for synthesizing MTT-type molecular sieves and maintaining the mixture under crystallization conditions sufficient to form product. The product molecular sieve is subjected to a pre-calcination step, and ion-exchange to remove extra-framework cations, and a post-calcination step. The molecular sieve has a MTT-type framework and a H-D exchangeable acid site density of 0 to 50% relative to molecular sieve SSZ-32.

A process for removing non-volatile, particulate mercury from crudes and condensates is disclosed. Particulate mercury in crudes can be removed by a process of first adding a halogen, such as I.sub.2. The halogen converts at least 10% of the particulate mercury into an oil-soluble mercury compound that cannot be removed by filtration or centrifugation. This oil-soluble mercury compound can then be removed by adsorption onto a solid adsorbent. The process can operate at near ambient conditions. The adsorption step can be carried out by mixing a particulate adsorbent in the halogen-treated crude and then removing it by centrifugation, desalting, filtration, hydrocyclone or by settling.
